Повний текст джерелаInjuries to people living and working on farms in New South Wales continue to be a significant burden on the health system, Workers’ Compensation system, agricultural industries and farming families. Strategies to reduce the number and severity of injuries suffered by farmers and people working on farms rely on accurate information. Unfortunately there is no one dataset available to describe the circumstances surrounding farm injuries and the size of this burden in Australia. Hence, a number of different data sources are required to provide a picture of farm injuries. To date, there has been very little critical examination of what value each of these datasets provides to describing farm injuries. This Thesis aimed to: • Undertake surveillance of injuries occurring to people on farms or during agricultural production in NSW using data from an Emergency Department, NSW Hospital Separations information, NSW Workers’ Compensation Claims, and ABS Deaths data. • Critically examine the utility of Emergency Department, Hospital, Workers’ Compensation, and ABS Deaths Data for the surveillance of farm injuries in NSW. • Critically examine data classification systems used in Emergency Department, Hospital, Workers’ Compensation, and ABS Deaths data collections to describe the breadth of farm injuries in NSW. • Define the priority areas for farm injury prevention initiatives in NSW based on the information obtained from the examination of the data from Emergency Department, Hospital, Workers’ Compensation, and ABS Deaths. • Evaluate the effectiveness of the NSW Rollover Protective Structure (ROPS) rebate scheme and examine the utility of the data currently available in NSW to measure the performance of the program. Four datasets, Tamworth Emergency Department, Hospital Separations, Workers’ Compensation and the Australian Bureau of Statistics (ABS) Deaths data were used to provide information on the surveillance of farm injuries, describe the breadth of classifications used to describe farm injuries, and define priorities for the prevention of farm injuries. There were 384 farm-related injuries which presented to the Emergency Department at the Tamworth Base Hospital between 1 September 1997 and 31 August 1998. Emergency Department data collected in this study used the Farm Injury Optimal Dataset (FIOD) for classification, which allowed for a comprehensive picture of the circumstances surrounding the injury event. The three most common external causes of injury were related to horses, motorcycles, and animals. Commonly people were working at the time of injury. Children represented 21% of the people injured. The average number of injuries per 100 farms per annum was 34.7. An examination of hospital discharge data for NSW was undertaken for the period 1 July 1992 to 30 June 2000 where the location of the injury was a farm. Classification of cases in this dataset conformed to the International Classification of Disease (ICD) versions 9 and 10. There were 14,490 people who were injured on a farm during the study period. The three most common external causes of injury were motorcycles, animals being ridden and agricultural machinery. Children represented 17% of all farm injury cases. The rate per 1,000 farms ranged from 19 to 42 per annum. An examination of Workers’ Compensation claims for agricultural industries in NSW between 1 July 1992 and 30 June 2001 was undertaken. The ‘Type of Occurrence’ classification system was used to code the claims. There were 24,332 claims of which the majority were males (82%). The incidence of injury / disease in agriculture per annum varied from 37 per 1,000 workers to 73 per 1,000 workers. The rate per 1,000 agricultural establishments varied from 54 to 76. The average cost of a claim was $10,880 and the average time lost per claims was 9.2 weeks. There were 81 deaths and 3,158 permanent disabilities. The three most common agents were sheep / goats (5%), ferrous and non-ferrous metals (5%), crates / cartons / boxes / etc (5%). Using ABS deaths data to examine the deaths of people working and living on farms was limited to males whose occupation was recorded as ‘farmer and farm manager’ and ‘agricultural labourer and related worker’. There were 952 deaths over the period 1 January 1991 and 31 December 2000. The information provided a consistent series of cases over time. Areas where prevention should be directed included motor vehicle accidents; falls; agricultural machinery; other machinery; firearms; poisoning; and drowning. Using any one of the datasets alone to examine people injured on farms not only underestimates the number of people injured, but also misses particular types of agents involved in farm injuries. Each of the datasets used in this Thesis provides a different perspective of farm injury in NSW. By examining the information together, there are a number of areas which are consistently represented in each dataset such as falls and agricultural machinery. While no one dataset provided all the information that would be useful for the prevention of injuries, the available information does provide direction for the development of prevention strategies. The overall weakness of the information provided is that it misses a number of risk factors that contribute to farm injuries such as fatigue and training. The lack of appropriate denominator information also makes it difficult to directly compare the datasets and estimate the size of the problem. There are a number of additional coding categories that could be included in each dataset that would provide a better understanding of the different groups at risk of sustaining an injury on a farm or during agricultural work. These coding categories include activity at time of injury, admission to hospital, and occupation. An example of the use of data to determine the effectiveness of a farm injury prevention program is the ‘NSW Rollover Protective Structure (ROPS) Rebate Scheme’ evaluation. Tractor rollover deaths have been identified as an issue for prevention by Farmsafe Australia; however, such deaths were not identified in any of the datasets used in this Thesis due to coding limitations in the ABS data. In this Thesis information about the evaluation of the ‘NSW ROPS Rebate Scheme’ is presented. The scheme was successful in fitting 10,449 ROPS to tractors and the following lessons were learnt: when providing a rebate, the administration (i.e. sending the cheque) needs to be done well; advertising is important and should be co-ordinated, increase the awareness of the risk(s) the intervention is aiming to prevent and effectiveness of subsequent solution (s); the program should ensure there is an increased awareness of the outcome the intervention is aiming to prevent; if regulation is part of the program, enforcement needs to undertaken; and should address any barriers to uptake. The information provided in this Thesis highlights the substantial burden that farm injury places on the agricultural and rural sector of NSW. While there is no one data source that can describe the circumstances and the burden of farm injuries, the currently available datasets do provide an insight into the circumstances of farm injuries and the burden these injuries place on health, Workers’ Compensation, agricultural industries and farming families.

Повний текст джерелаResponsible Government began in New South Wales in 1856. Direct participation by women began 70 years later in 1925 with the election of Millicent Preston-Stanley. Her first speech questioned whether Parliament was a fit place for women. Another significant milestone was reached after another 70 years when female MLAs in the Fifty-first Parliament constituted 15% of the Legislative Assembly and female MLCs made up 33% of the Legislative Council. In the 1990s there was no formal barrier to the participation of persons on the basis of their sex but no scholarly study had addressed the question of whether the Parliament’s culture was open to all gender orientations. This study examines the hypothesis that the Parliament informally favoured some types of gender behaviour over others. It identifies ‘gender’ as behaviour rather than a characteristic of persons and avoids the conflation of gender with sex, and particularly with women exclusively. The research used interviews, observation and document study for triangulation. The thesis describes the specific context of New South Wales parliamentary politics 1995-1999 with an emphasis on factors that affect an understanding of gender. It explores notions of representation held by MPs, analyses their personal backgrounds and reports on gender-rich behaviours in the chambers. The study concludes that gender was a significant factor in the behaviour of Members of the Parliament. There were important differences between the ways that male and female MPs approached their roles. Analysis of the concept of gender in the Parliament shows that some behaviours are more likely to bring political success than are others. The methodology developed here by adapting literature from other systems has important strengths. The data suggest that there is a need for many more detailed studies of aspects of gender in parliaments.

Geomorphology, archaeology and geoarchaeology: introduction and background -- Surface stone artefact scatters: why can we see them? -- Geomorphic controls on spatial patterning of the surface stone artefact record -- A temporal framework for interpreting surface artefact scatters in Western NSW -- Synthesis: stone artefact scatters in a dynamic landscape.
Surface scatters of stone artefacts are the most ubiquitous feature of the Australian Aboriginal archaeological record, yet the most underutilized by archaeologists in developing models of Aboriginal prehistory. Among the many reasons for this are the lack of understanding of geomorphic processes that have exposed them, and the lack of a suitable chronological framework for investigating Aboriginal 'use of place'. This thesis addresses both of these issues. -- In arid western NSW, erosion and deposition accelerated as a result of the introduction of sheep grazing in the mid 1800s has resulted in exposure of artefact scatters in some areas, burial in others, and complete removal in those parts of the landscape subject to concentrated flood flows. The result is a patchwork of artefact scatters exhibiting various degrees of preservation, exposure and visibility. My research at Stud Creek, in Sturt National Park in far western NSW, develops artefact and landscape survey protocols to accommodate this dynamic geomorphic setting. A sampling strategy stratified on the basis of landscape morphodynamics is presented that allows archaeologists to target areas of maximum artefact exposure and minimum post-discard disturbance. Differential artefact visibility at the time of the survey is accommodated by incorporating measures of surface cover which quantify the effects of various ephemeral environmental processes, such as deposition of sediments, vegetation growth, and bioturbation, on artefact count. -- While surface stone artefact scatters lack the stratigraphy usually considered necessary for establishing the timing of Aboriginal occupation, a combination of radiocarbon determinations on associated heat-retainer ovens, and stratigraphic analysis and dating of the valley fills which underlie the scatters, allows a two-stage chronology for huntergatherer activity to be developed. In the Stud Creek study area, dating of the valley fill by OSL established a maximum age of 2,040±100 y for surface artefact scatters. The heatretainer ovens ranged in age from 1630±30 y BP to 220±55 y BP. Bayesian statistical analysis of the sample of 28 radiocarbon determinations supported the notion, already established from analysis of the artefacts, that the Stud Creek valley was occupied intermittently for short durations over a relatively long period of time, rather than intensively occupied at any one time. Furthermore, a gap in oven building between about 800 and 1100 years ago was evident. Environmental explanations for this gap are explored, but the paiaeoenvironmental record for this part of the Australian arid zone is too sparse and too coarse to provide explanations of human behaviour on time scales of just a few hundred years. -- Having established a model for Stud Creek of episodic landscape change throughout the late Pleistocene and Holocene, right up to European contact, its veracity was evaluated in a pilot study at another location within the region. The length of the archaeological record preserved in three geomorphically distinct locations at Fowlers Gap, 250 km south of Stud Creek, is a function of geomorphic dynamics, with a record of a few hundred years from sites located on channel margins and low terraces, and the longest record thus far of around 5,000 years from high terrace surfaces more remote from active channel incision. But even here, the record is not continuous, and like Stud Creek, the gaps are interpreted to indicate that Aboriginal people moved into and out of these places intermittently throughout the mid to late Holocene. -- I conclude that episodic nonequilibrium characterizes the geomorphic history of these arid landscapes, with impacts on the preservation of the archaeological record. Dating of both archaeological and landform features shows that the landscape, and the archaeological record it preserves, are both spatially and temporally disjointed. Models of Aboriginal hunter-gatherer behaviour and settlement patterns must take account of these discontinuities in an archaeological record that is controlled by geomorphic activity. -- I propose a new geoarchaeological framework for landscape-based studies of surface artefact scatters that incorporates geomorphic analysis and dating of landscapes, as well as tool typology, into the interpretation of spatial and temporal patterns of Aboriginal huntergatherer 'use of place'.

Повний текст джерелаThis thesis is about the substantial service Karitane provided in the teaching of mothercraft to guide parents in the care of their young children in New South Wales. At first called the Australian Mothercraft Society, it emerged in New South Wales as a voluntary organisation in 1923, closely allied to New Zealand’s Plunket Society founded in 1907 by Sir Truby King. Karitane was at its most active in the 1940s when it provided over a quarter of Sydney’s residential mothercraft services. Its beginnings were overshadowed by conflict and the New South Wales Department of Public Health did not acknowledge Karitane until the 1960s. Until then Karitane was absent from the public record of services for mother and baby in NSW. Sydney’s Eastern Suburbs community and the Karitane Products Society in New Zealand supported Karitane before it integrated into New South Wales’ government supported health services. Throughout it delivered on its aims of teaching mothers ways of caring for infants, disseminating knowledge about the care of young children and preparing specialist nurses. The main theme of this thesis is the ‘moving frontier’ that is the boundary between the voluntary providers of health services and governmental provision of health services. Karitane’s development has depended on the politics of health care at Commonwealth, State and local levels. The secondary themes derive from the competition for scarce resources amongst the professional groups involved; doctors, nurses and health service administrators. Karitane’s experience has not been unique; it has followed a trajectory common to voluntary organizations providing personal care services through the twentieth century and it has conformed to trends in public health. Sometimes Karitane led the trends and sometimes it trailed; it adapted to circumstances but it retains a degree of independence. Shining through all the problems with resources are the human experiences of appreciative mothers who used Karitane’s services and the dedicated staff and supporters who provided mothercentred help with the care of infants. The mother/infant relationship continues to be a central concern for public health. This study of Karitane gives a longitudinal perspective on the contribution of a small band of skilled people with a clear mission to provide services to assist mothers with their babies and young children.

Повний текст джерелаMineral carbonation, the reaction of Mg-, Ca- or Fe-rich silicates or oxides with CO₂ to form stable, environmentally benign carbonates, is a promising strategy to mitigate rising CO₂ concentrations in the atmosphere and the associated adverse climate effects. Serpentinite, considered as a highly suitable feedstock for mineral carbonation, due to its high Mg-content and worldwide abundance, naturally transforms into Mg-carbonate, providing insight into the carbonation process. Understanding of these natural analogues to mineral carbonation is an important step in the implementation and optimisation of processes for industrial carbon storage in minerals. This study characterises the natural carbonation of serpentinite and associated ultramafic rocks in the Great serpentinite Belt (GSB), New South Wales, Australia. Based on the formation of the Attunga magnesite deposit and the carbonation of ultramafic mine tailings at the Woodsreef Asbestos Mine, and in comparison to the well document hydrothermal formation of silica-carbonate rock, it provides a record of the textural, geochemical and mineralogical evolution during natural carbonation and identifies the conditions and mechanisms promoting natural storage of CO₂. Nodular, cryptocrystalline magnesite at Attunga occurs in irregular veins and stock-works that are spatially associated with the weathering horizon. Textures and stable oxygen isotope signatures of the magnesite are in accordance with a supergene formation from meteoric waters at surfacial temperatures. Low δ¹³C signatures suggest C3 photosynthetic plants as the main carbon source and a typical shift of stable isotopic composition towards low δ¹³C and high δ¹⁸O can be observed in other weathering-affected carbonate occurrences in the study area. The supergene character of the precipitating fluids is confirmed by low radiocarbon concentrations of the magnesite and the previously suggested incorporation of carbon from decarboxylation of sub-ducted sediments into this type of deposit can be excluded. Some textural evidence indicates the presence of a pre-existing, possibly hydrothermal, magnesite deposit, which has been overprinted by dissolution and re-precipitation during weathering, but textural observations on the outcrop- and micro-scale indicate that weathering of the serpentinite host rock is the major magnesite mineralisation-process. Consequently, the formation of the Attunga magnesite has occurred during Quaternary weathering of the serpentinite host rock and a pre-existing magnesite deposit and is best described by a low temperature hypogene-supergene genetic model involving meteoric waters, which acquire CO₂ from the soil zone. Progress of carbonation at Attunga is strongly dependent on access of CO₂-bearing fluids, which initially is structurally controlled, but dominated by dissolution-derived porosity during progressive stages of alteration. Incipient weathering of tectonised serpentinite by moderately acidic, meteoric waters induces initially incongruent dissolution of least stable minerals (olivine, andradite, diopside and lizardite) and creates a range of porous and reactive alteration products, such as the deweylite assemblage. Progressive dissolution of the serpentinite host rock leads to a concomitant rise in Mg²⁺ concentrations and pH, which, together with the presence of pre-existing magnesite nucleation sites and minor evaporation of fluids, promote carbonate precipitation. Desiccated surfaces and secondary porosity suggest that, magnesite formation has progressed via dehydration of a basic, hydrated precursor carbonate such as hydromagnesite. Late stage precipitation of opal-A, derived from complete serpentine disintegration and advanced carbonation, clogs pore spaces and leads to subsequent cessation of carbonation at Attunga. Serpentinite-carbonation at Attunga occurs by both direct replacement in pervasive alteration zones and in a two step process, involving dissolution of serpentine and precipitation of carbonate in separate rock volumes. Weathering creates a permeability front in advance of the reaction front, which enhances fluid infiltration and reactivity for subsequent carbonation. The amount of net CO₂ sequestration and the rates of carbonation can be estimated based on radiocarbon age constraints and textural observations. Since closure of the Woodsreef Asbestos Mine in 1983, recessive weathering of fine grained material has led to the formation of extensive carbonate-rich crusts on the surface of the mine tailings pile. A relationship between the mode of carbonate occurrence, the mineralogy and the isotopic fingerprint of carbonates of the collected samples can be observed. Hydrated Mg-carbonate hydromagnesite is the main component of vertical carbonate crusts and has precipitated from evaporating meteoric waters incorporating atmospheric CO₂, as reflected in high δ¹⁸O, δ¹³C and F¹⁴C signatures, respectively. Bedrock carbonate, which has formed during alteration of the serpentinite bedrock before mining, is present in the form of low and variable concentrations of magnesite, dolomite and calcite. It is characterised by moderately high δ¹⁸O, low δ¹³C and F¹⁴C, a signature typical for ‘weathering-derived’ magnesite deposits in the GSB. The carbonate fraction of deep cement samples, collected from 70 and 120 cm below the surface, representing the bulk tailings material at depth, predominantly consists of pyroaurite. Despite stable isotope signatures similar to bedrock, the deep cement samples contain significant radiocarbon. Pyroaurite, forming under different conditions as hydromagnesite, may thus represent an additional trap for atmospheric CO₂ in the Woodsreef mine tailings. The radiocarbon content of crust samples strongly suggests atmospheric CO₂ as the dominant carbon source, but δ¹³C is lower than expected for carbonate that forms in exchange equilibrium with atmospheric CO₂. This could either be a result of admixing of carbon from a modern, organic carbon source, such as microbial respiration, or of kinetic isotope effects during uptake of atmospheric CO₂ into moderately high pH waters. The distribution of carbonates and SiO₂-phases, together with the absence of isotopic mixing trends between bedrock carbonate and atmospheric-derived carbonate, strongly suggest that, dissolution and re-precipitation (‘recyling’) of bedrock carbonate is not a dominant process in the Woodsreef tailings. Cations for carbonate precipitation are instead derived from the dissolution of serpentine minerals (lizardite and chrysotile) and brucite. Quantitative methods are used with X-ray diffraction data to estimate the abundance of the two major carbonate minerals hydromagnesite and pyroaurite and to constrain minimal and maximal carbonation rates, considering only the former or both minerals together, respectively. The formation of weathering-derived magnesite deposits, carbonate crusts on mine tailings and silica-carbonate rock reflect several sets of conditions promoting natural carbonation and accordingly produce texturally, geochemically and mineralogically distinct carbonation products. Both the formation of the Attunga magnesite deposit and the carbonate crusts on mine tailings at Woodsreef are closely associated with weathering of serpentinite, i.e. dissolution of serpentine minerals in CO₂-bearing meteoric water and precipitation of hydrated magnesite precursor minerals at ambient temperatures and pressures in a system that is open with respect to CO₂. Distinct isotope signatures reflect a higher degree of fluid evaporation and the recent sequestration of atmospheric CO₂ into carbonates at Woodsreef, as opposed to organically-derived carbon stored during Quaternary weathering at Attunga. The rates of carbonation at Attunga are higher than the background uptake rate of CO₂ by chemical weathering, but, due to the higher surface area of the tailings and possibly to the presence of reactive brucite and chrysotile, they are significantly slower than carbonation at Woodsreef. The reactive surface area of coherent, non-disintegrated serpentinite at Attunga is initially created by faulting and fracturing during tectonic activity and physical weathering, but dominated by dissolution reactions during later, more advanced stages of alteration. Silica-carbonate rocks in the GSB form due to hypogene serpentinite alteration at temperatures of 165 to 225 °C by distinct metamorphic/magmatic fluids in a closed system with respect to CO₂. It is likely that the abundance and massive character of the silica-carbonate rock in the GSB reflects the more effective natural carbonation of serpentinite at elevated temperatures and reaction rates. Each of the studied natural analogues has the potential for application to a process of enhanced industrial storage of CO₂ in serpentinite rocks. The development of porosity and fluid access during low temperature weathering-carbonation of coherent serpentinite at Attunga bears important implications for in-situ mineral carbonation. The acceleration of natural carbonation rates and the direct sequestration of atmospheric CO₂ in carbonate crust on the mine tailings at Woodsreef represent a promising strategy for a low-cost, low energy CO₂ storage process. Silica-carbonate rock formation occurs under conditions that are optimal for injection of hot CO₂-bearing fluids during in-situ carbonation, and, due to elevated temperatures and pressures, resembles ex-situ mineral carbonation approaches.

Повний текст джерелаThis present contribution addresses the most important impediment for a large scale implementation of sequestering CO₂ by mineralisation, the energy cost of dehydroxylation of serpentinite ores. The current work, based on a practical heat activation strategy, provides reasonable energy and cost estimates of the thermal treatment of serpentine. A practical heat activation strategy comprises prograde heating to yield a material containing 20 % OHres and employs heat integration to recover ~80 % of the sensible heat from the dehydroxylated mineral. This study also reconfirms that crystallinity primarily controls magnesium availability. Once dehydroxylated, overheating must be avoided to prevent the material from recrystallising. Significant loss of crystallinity commences by ~ 50 % OHres, peaks at about 20 % OHres, and terminates beyond 5 % OHres. Besides limiting crystallinity, entrapment of liberated water and the formation of hematite must be minimised or altogether eliminated. The fluidisation of the reactor bed and the use of CO₂ as purge gas combined with prior demagnetisation circumvent these limiting factors. Furthermore, the rapid thermal treatment of 75 µm particles allows for optimal conditions of temperature and rate of dehydroxylation and presents a practical means to increase the throughput and minimise reactor size. Examination of the prior studies on the dehydroxylation of serpentine minerals identified the knowledge gaps that require addressing. This review surveys the key concepts, including the chemical and physical transformations involving the proposed mechanisms, thermal stability, reaction kinetics, the formation of intermediates and products, associated heat requirements, factors that influence the reaction, as well as associated enhancements in both dissolution and carbonation. The review finds the activation processes must avoid recrystallisation of disordered phases to forsterite and enstatite, and minimise the partial pressure of water vapour, which engenders reverse reaction. In particular, this current study determined the suitability of the serpentinite resource from the Great Serpentinite Belt in New South Wales for thermal activation using thermal, X-ray and spectroscopic techniques. Experimental investigations designed to evaluate the thermal behaviour and structural transformations of serpentine minerals include thermogravimetry-derivative thermogravimetry, mass spectrometry, X-ray diffraction and magic angle spinning nuclear magnetic resonance. We focussed on antigorite as the model serpentine mineral for these studies, however, we include the other serpentine minerals, lizardite and chrysotile as well as partially serpentinised samples in subsequent energy measurements by thermogravimetry-differential scanning calorimetry. We first analysed the changes in antigorite’s derivative thermogravimetric curves (DTG) and deduced factors affecting the mass loss profiles to serve as guide in both fundamental studies and in the design of a scale-up dehydroxylation reactor. The imposed heating rate, type of purge gas, type of comminution and sample mass all influence the dehydroxylation curve. However, the results show no influence of material of construction of the heating vessel and flow rate of the purge gas. We report an important effect of oxidation of Fe²⁺ under air purge gas that occurs prior to dehydroxylation and leads to formation of hematite skins on serpentinite particles, slowing down subsequent mass transfer and increasing the processing temperature. Design considerations of a practical scale up reactor for activating serpentinite ores for storing CO₂ by carbonation ought to comprise rapid heating, proper size reduction, prior demagnetisation and fluidisation of the powdered bed. We then demonstrate the optimisation of heat treatment of antigorite, to provide a benchmark of an extreme case of activation among serpentine minerals. Antigorite was investigated non-isothermally via thermogravimetry-mass spectrometry and in-situ X-ray powder diffraction, its thermal reaction sequence elucidated and reaction kinetics subsequently modelled. Here we describe a predictive framework expedient to the thermal processing of serpentinites for the mineralisation of CO₂. We successfully modelled an optimised thermal dehydroxylation strategy for antigorite using a three-dimensional phase boundary reaction model (R3), with activation energy Ea of 160 kJ mol⁻¹ and a frequency factor A of 5.7 ± 4.1 × 10⁵ s⁻¹ (5.7 × 10⁵ s⁻¹ for dynamic and 1.6 × 10⁵ s⁻¹ for static stage). This strategy translates to a fast and efficient thermal processing in an optimally-sized calcining vessel. Furthermore, the results imply that activation of the more common serpentine minerals lizardite and chrysotile would be significantly less energy intensive as their dehydroxylation proceeds at lower temperatures than that of antigorite. We also investigated the local chemical environment of thermally treated antigorite to elucidate the structural transformations that take place during its dehydroxylation. A combination of ²⁹Si and ²⁵Mg magic angle spinning nuclear magnetic resonance (MAS NMR) spectroscopy, phase compositional analysis and morphological observations served to characterise these transformations. The results indicate that, whilst the octahedral sheet remained relatively immobile, the tetrahedral sheet demonstrated a range of movements. This progressive break-up of the silicate sheet leads to various SiO₄ tetrahedral polymerisation and the formation of two intermediate phases, dehydroxylate 1 and dehydroxylate 2. These metastable phases possess similar Mg octahedral environment, but differ in the local configuration of SiO₄ tetrahedra. The results suggest that crystallinity plays a significant role in antigorite dehydroxylation wherein partially amorphised regions dehydroxylate preferentially. For applications to mineralisation of CO₂, once dehydroxylated, the formation of new crystalline phases must be minimised in order to maximise the loss of crystallinity. The combined chemical, morphological and physical evidence implies that significant loss of crystallinity commences at about 50 % OHres until about 5 % OHres. Finally, we present realistic cost estimates based on a practical heat activation strategy for serpentinites. By comparing serpentinites from the Great Serpentinite Belt to those found in Coolac Serpentinite Belt, we found the former more suitable for heat activation under a practical heat activation strategy. Based on the research findings, the thermal activation of serpentine minerals from the Great Serpentinite Belt (GSB) presents a practical option to New South Wales for the mineralisation of CO₂. Heat activation of the GSB serpentinites is best performed via prograde heating to about 680 °C to yield an active material with 20 % OHres and requires an energy input of at least 541 MJ (tSerpentinite)⁻¹. The operational cost of thermally activating GSB serpentinites is about AU$ 1.25 per tonne of available active serpentine and with a corresponding CO₂ penalty of about 7 %.

Повний текст джерелаSulfur- and lead-isotope signatures for 64 deposits/systems located in the Central and Easternn Subprovinces of the Lachlan Orogen in eastern New South Wales were characterised in the present study. Here are presented four new ⁴⁰Ar/³⁹Ar dates, 644 new sulfur- and 105 new leadisotope analyses, plus a collation of 386 unpublished and 277 published sulfur isotope and over 560 unpublished and published lead isotope analyses for middle Silurian to Early Carboniferous mineralisation. Measured δ³⁴S values for 22 VHMS deposits range between -7.4‰ to 38.3‰. S-isotope values for Currawang East, Lewis Ponds, Mount Bulga, Belara and Accost (Group 1) range from - 1.7‰ to 5.9‰ with the ore-forming fluids for this group of deposits likely to have been reducing and sulfur derived largely from magmatic sources. By contrast, S-isotope signatures for sulfides from Black Springs, Calula, Captains Flat, Commonwealth, Cordillera, Gurrundah, Kempfield, Peelwood mine, Sunny Corner, The Glen, Wet Lagoon and Woodlawn (Group 2) have average δ³⁴S values between 5.4‰ and 8.1‰. These deposits appear to have formed from ore fluids that were more oxidising than those for Group 1 deposits, representing a mixed contribution of sulfur derived from partial reduction of seawater sulfate, in addition to sulfur from other sources. Four deposits, Elsinora, John Fardy, Mount Costigan and Stringers, have heavier average δ³⁴S signatures (10.1‰ to 13.2‰) than Group 2 deposits, suggesting that these deposits included a greater component of sulfur of seawater origin. The S-isotope data for barite from Black Springs, Commonwealth, Stringers, Gurrundah, Kempfield and Woodlawn range from 12.6‰ to 38.3‰. Over 80% of the δ³⁴S values are between 23.4‰ and 30.9‰, close to the previously published estimates for the composition of seawater sulfate during Late Silurian to earliest Devonian times, providing supporting evidence that these deposits formed concurrently with a Late Silurian volcanic event. New Pb isotope data for eleven VHMS deposits included in the present study support earlier Pb-isotope studies which indicate that lead was largely sourced from the host sequence. However, the data for Black Springs, Elsinora and Commonwealth indicate that some lead, included in these deposits, was sourced from units forming basement to the Silurian troughs. Sulfur isotope values for thirteen orogenic gold systems range between -7.5‰ and 16.1‰ (excluding outliers). The Wyoming One–Myall United system has an average δ³⁴S value of -5.5‰ and a primitive mantle-derived lead isotope signature implying that sulfur and gold were sourced from a fractionated mantle-derived intrusion. The δ-isotope data for Adelong, Bodangora, Calarie, Hargraves, Hill End, London–Victoria, Sebastopol, Sofala–Wattle Flat and Stuart Town are all very similar with average δ³⁴S values close to 0‰ (range -2.8 to 3.4‰). Sulfur in these deposits was derived from reduced fluids, sources from magmatic reservoirs either as a direct input or through dissolution and recycling of rock sulfide. For deposits hosted by the northern HET it is suggested that sulfur and gold were sourced from mantle-derived units located beneath the HET rather than the siliclastic fill of the trough itself. Windeyer and Napoleon Reefs have heavier S-isotope signatures suggesting a greater contribution of sulfur derived from reduced seawater sulfate reservoirs. Springfield, located adjacent to the northern HET, has the heaviest S-isotope signature (15.4 δ³⁴S‰) for orogenic gold deposits included in the present study. For this deposit it is suggested that HET-derived basinal fluids containing reduced seawater sulfate migrated along faults and leached gold from Ordovician mantle-derived units forming basement to that area. Seven sulfide-rich orogenic base metal deposits were included in the present study. Average δ³⁴S values for Currawang South, Frogmore, Montrose, Ruby Creek, Wallah Wallah vary between 3.5‰ and 6.0‰ (Group 1), with Kangiara, and Lucky Hit–Merrilla, having heavier average δ³⁴S values (10.0‰ and 8.2‰ respectively — Group 2). Group 1 deposits are small, and S-isotope signatures suggest significant sulfur was sourced from magmatic reservoirs; whereas, Group 2 deposits are larger and δ³⁴S signatures indicate a larger component of sulfur was derived from reduced seawater sulfate reservoirs. The Pb-isotope data for these deposits suggest that the majority of the lead was derived from older Ordovician and Silurian crustal reservoirs. The data for Mount Werong and Merrilla support a Middle Devonian Pb-model age; whereas, those for Wallah Wallah point to an Early Carboniferous Pb-model age. Browns Reef, in the Central Subprovince, is now interpreted to be a syn-deformational orogenic base metal deposit, for which the S-isotope data are similar to Group 2 orogenic base metal deposits and Pb-isotope data suggest lead was sourced from the fill of the Rast Trough. Five epithermal systems were included in the present study. Bauloora, Bowdens and those in the Yerranderie district are intermediate-sulfidation epithermal systems; whereas, Yalwal and Pambula are low sulfidation epithermal systems. Yerranderie, Yalwal, Pambula and Bauloora have δ³⁴S values close to 0‰. Sulfur in these deposits was derived largely from a magmatic reservoir. The Yerranderie system is zoned with respect to S-isotope distribution and shows mineralogical zonation along the Yerranderie Fault. Yalwal is zoned with 0‰ S-isotope values correlating with sericitic alteration assemblages and heavier S-isotope values (up to 17.9 δ³⁴S‰) correlating with assemblages that include minerals characteristic of argillic alteration. Sixteen middle Silurian to Early Devonian intrusion-related deposits were included in the present study. Collector, Dargues Reef, Mayfield, Ryans, Tallawang, Whipstick and Yambulla are located east of the I–S granite line, with Dargues Reef, Majors Creek, Mayfield, Whipstick and Yambulla hosted by or adjacent to their causative intrusion. These deposits have S-isotope signatures close to 0‰ (range -3.6‰ to 3.0‰) similar to that for granites east of the I–S line (range -1.5‰ to 4.9‰). The Pb-isotope data for these deposits includes both crustal- and mantle-derived lead. Deposits distal to their causative intrusions (Collector and Ryans) have heavier S-isotope signatures (7.7‰ and 4.3‰ respectively) indicating that some sulfur was probably sourced from the host sequence. The majority of lead, for these deposits, was sourced from the host sequence and/or older reservoirs. The S-isotope data for Tallawang suggest that the sulfur was largely sourced from the host sequence. Eight deposits are located to the west of the I–S line. Nasdaq, Phoenix, Tara, Rye Park and Mineral Hill have heavier S-isotope signatures (range: 2.6‰ to 7.3‰) which overlap with the range of values typical of granites located to the west of the I–S line (1.9 to 9.6‰) supporting the interpretation that the majority of sulfur was derived from the causative intrusion. The Pb-isotope data for Nasdaq, Mineral Hill and Tara suggest that lead originated from the host sequence or from older lead reservoirs; whereas, at Rye Park and Phoenix lead was probably sourced from the causative intrusion. Ardlethan and Browns Creek deposits have near 0‰ S-isotope signatures, lower than the range of δ³⁴S values for granites west of the I–S line which is accounted for by mantle-derived volatiles and a possible biogenic sulfur component. The Pb-isotope data for these two deposits are consistent with a lead sourced largely from the causative intrusion; although, some mantlederived lead is probably present. Red Hill has the highest S-isotope signature (13.7‰) indicating that the majority of sulfur was sourced from a seawater sulfate reservoir. ⁴⁰Ar/³⁹Ar dating showed that intrusion-related mineralisation at Tara formed at 420 ± 2 Ma; VHMS-related mineralisation at The Glen (Glen E deposit) formed at 418.2 ± 2.2 Ma; and that the Yerranderie and Bauloora intermediate sulfidation epithermal systems formed at 372.1 ± 1.9 Ma and 371 ± 13 Ma (respectively). New dating plus a review of timing constraints to Tabberabberan and Kanimblan cycle-related mineralisation highlighted metallogenic events at ~430 Ma (intrusion-related), ~420 Ma (intrusion- and VHMS-related) and a mid Devonian epithermal event. The timing of orogenic-related mineralisation is diachronous across the study area with the majority of orogenic gold systems in the west forming during the Middle Devonian Tabberabberan Orogeny; whereas, similar mineralisation in the northern HET formed during the Early Carboniferous Kanimblan Orogeny.
