Mineralogical Magazine 52, no. 365 (April 1988): 237–40. http://dx.doi.org/10.1180/minmag.1988.052.365.10.

AbstractEcandrewsite, the zinc analogue of ilmenite, is a new mineral which was first described from the Broken Hill lode in 1970 and discovered subsequently in ores from Little Broken Hill (New South Wales) and the San Valentin Mine, Spain. The name ‘ecandrewsite’ was used in a partial description of the mineral in ‘Minerals of Broken Hill’ (1982), thereby establishing the Little Broken Hill locality, specifically the Melbourne Rockwell Mine, as the type locality. Microprobe analysis of ecandrewsite from the type locality gave ZnO 30.42 (wt.%), FeO (total Fe) 11.37, MnO 7.64, TiO2 50.12, total 99.6%, yielding an empirical formula of (Zn0.59Fe0.24Mn0.17)1.00Ti0.99O3 based on 3 oxygen atoms. All compositions from Little Broken Hill and the San Valentin Mine are ferroan manganoan ecandrewsite. The strongest lines in the X-ray powder diffraction data are (d in Å, (hkil), I/Io):2.746, (104), 100; 2.545, (110), 80; 1.867, (024), 40; 3.734, (012), 30; 1.470, (3030), 30; 1.723, (116), 25. Ecandrewsite is hexagonal, space group RR3¯ assigned from a structural study, with a = 5.090(1), c = 14.036(2)Å, V = 314.6(3)Å3, Z = 6, D(calc.) = 4.99. The mineral is opaque, dark brown to black with a similar streak, and a submetallic lustre. In plane polarized light the reflection colour is greyish white with a pinkish tinge. Reflection pleochroism is weak, but anisotropism is strong with colours from greenish grey to dark brownish grey. Reflectance data in air between 470 and 650 nm are given. At the type locality, ecandrewsite forms disseminated tabular euhedral grains up to 250 × 50 µm, in quartz-rich metasediments. Associated minerals include almandine-spessartine, ferroan gahnite and rutile. The name is for E. C. Andrews, pioneering geologist in the Broken Hill region of New South Wales. Type material consisting of one grain is preserved in the Museum of Victoria (M35700). The mineral and name were approved by the IMA Commission on New Minerals and Mineral Names in 1979.

AbstractHoganite, copper(II) acetate monohydrate, and paceite (pronounced ‘pace-ite’), calcium(II) copper(II) tetraacetate hexahydrate, occur as isolated crystals embedded in ferruginous gossan from the Potosi Pit, Broken Hill, New South Wales, Australia. They are associated with goethite, hematite, quartz, linarite, malachite, azurite, cerussite and cuprian smithsonite. Hoganite is bluish green with a pale blue streak and a Mohs hardness of 1½; it possesses perfect {001} and distinct {110} cleavages and has a conchoidal fracture. Chemical analysis of hoganite gave (wt.%) C 23.85; H 3.95; Cu 31.6; Fe 0.4; O (by difference) 40.2, yielding an empirical formula of C4H7.89O5.07Cu1.00Fe0.01. The simplified formula is C4H8O5Cu or Cu(CH3COO)2.H2O, the mineral being identical to the synthetic compound of the same formula. Single-crystal X-ray data for hoganite are: monoclinic, space group C2/c, a = 13.162(3), b = 8.555(2), c = 13.850(3)Å, β = 117.08(3)°, Z = 8. The density, calculated from single-crystal data, is 1.910 g cm−3. The strongest lines in the X-ray powder pattern are [dobs (Iobs) (hkl)] 6.921 (100) (011); 3.532 (28) (202); 6.176 (14) (200); 3.592 (11) (1̄22); 5.382 (10) (2̄11); 2.278 (10) (204); 5.872 (9) (002). Hoganite (orientation presently unknown) is biaxial positive with α = 1.533(2), β = 1.541(3), γ = 1.554(2), 2V(meas.) = 85(5)°, 2V(calc.) = 76.8°, dispersion is r < v, medium (white light); it is strongly pleochroic with X = blue, Y = pale bluish, Z = pale bluish green and absorption X > Y > Z. The mineral is named after Graham P. Hogan of Broken Hill, New South Wales, Australia, a miner and well-known collector of Broken Hill minerals.Paceite is dark blue with a pale blue streak and a Mohs hardness of 1½; it possesses perfect {100} and {110} cleavages and has an uneven fracture. Chemical analysis of paceite gave (wt.%) C 21.25; H 5.3; Ca 9.0; Cu 14.1; O (by difference) 50.35, yielding an empirical formula of C8H23.77O14.23Ca1.02-Cu1.00. The simplified formula is C8H24O14CaCu or CaCu(CH3COO)4.6H2O, the mineral being identical to the synthetic compound of the same formula. Unit-cell data (refined from X-ray powder diffraction data) for paceite are: tetragonal, space group I4/m, a = 11.155(4), c = 16.236(17)Å, Z = 4. The density, calculated from refined cell data, is 1.472 g cm−3. The strongest lines in the X-ray powder pattern are [dobs (Iobs) (hkl)] 7.896 (100) (110); 3.530 (20) (310); 5.586 (15) (200); 8.132 (8) (002); 9.297 (6) (101); 2.497 (4) (420); 3.042 (3) (321). Paceite is uniaxial positive with ω = 1.439(2) and ɛ = 1.482(3) (white light); pleochroism is bluish with a greenish tint (O), pale bluish with a greyish tint (E), and absorption O ⩾ E. The mineral is named after Frank L. Pace of Broken Hill, New South Wales, Australia, an ex-miner and well-known collector of Broken Hill minerals.

AbstractNyholmite, Cd3Zn2(AsO3OH)2(AsO4)2·4H2O, from the Block 14 Opencut, Broken Hill, New South Wales, Australia, is a new Cd-Zn arsenate species, isostructural with the minerals of the hureaulite group. The mineral occurs in a quartz-garnet-arsenopyrite matrix as white globules, tufted aggregates of fibrous crystals and radiating hemispheres of thin, colourless, bladed crystals. Associated minerals are goldquarryite, lavendulan-sampleite, scorodite-strengite and gypsum. Individual crystals are up to 0.2 mm in length and 0.05 mm across. The mineral is transparent to translucent with a vitreous lustre. It is brittle with an uneven fracture and a white streak. The Mohs hardness is 3–3.5 and the calculated density is 4.23 g cm–3 for the empirical formula. Electron microprobe analyses yielded CdO 34.58, ZnO 9.72, MnO 3.59, CuO 3.39, Al2O3 0.20, CaO 0.16, PbO 0.37, As2O5 34.55, P2O5 6.29 totalling 92.85 wt.%. The empirical formula, based on 20 oxygen atoms, is Ca0.03Pb0.02 Cd2.80Al0.04Zn1.24-Cu0.44Mn0.53[(AsO4)3.13(PO4)0.92]Σ4.05H1.91·3.79H2O. Nyholmite is monoclinic, C2/c, a = 18.062(4) Å, b = 9.341(2) Å, c = 9.844(2) Å, β = 96.17(3)°, V = 1651.2(6) Å3 (single-crystal data, at 123 K). The six strongest lines in the X-ray powder diffraction pattern are [d(Å),I,(hkl)]: 8.985,30,(200); 8.283,85,(110); 6.169,25,(111); 4.878,25,(002); 3.234,100,(2, 420); 3.079,65,(222, 511); 2.976’45’(113). The crystal structure was solved by Patterson methods and refined using 2045 observed reflections to R1(F) = 3.73%. The structure is characterized by a kinked, five-membered chain of edge-sharing Mφ6 (φ = unspecified anion) octahedra, or pentamer, that extends in the a direction. The pentamers link by sharing corners to form a sheet in the (001) plane. Pentamers are also linked, via corner-sharing, by (As,P)O4 groups forming thick slabs in the (001) plane. The slabs link in the c direction by cornersharing between octahedra and tetrahedra to form a dense heteropolyhedral framework. Moderate to weak hydrogen-bonding provides additional linkage between the slabs.

Full textAbstract:
AbstractSpecimens of honey-brown to pinkish-brown globular carbonates encrusting concretionary goethite–coronadite from the oxidized zone at Broken Hill, New South Wales, have compositions in the rhodochrosite–smithsonite series. This may be the first extensive natural occurrence of this solid-solution series. Growth of the carbonates occurred in zones which have near uniform composition. The ratio MnCO3/(MnCO3 + ZnCO3) for each zone bears a linear relationship to the measured d spacing for the 104 X-ray reflections. Because cerussite is the only other mineral associated with the Zn-Mn carbonates and because of an absence of detailed locality information, the paragenetic significance of these minerals cannot be determined. The solutions depositing them may have been derived from the near-surface equivalents of the Zinc Lode horizons.

Abstract Microprobe analysis of marshite and miersite from Broken Hill, Australia, demonstrate extensive solid solution between the end-members CuI and AgI, indicating the possibility of a complete solid-solution series. Unit-cell parameters increase from 6.054 Å for marshite to 6.504 Å for miersite, closely following Vegard's Law. The Cu content of iodargyrite is generally below the limit of detection, but one zoned crystal contained 0.28 wt.% Cu. Crystallization of either miersite or iodargyrite at Broken Hill appears to be dependent upon the local availability and ratio of copper, silver and iodine ions.

Full textAbstract:
This dissertation examines the evolution of the mining industry in three British dominions during the late nineteenth and early twentieth centuries. Adopting a case study approach, it describes the establishment and growth of mining in Rossland, British Columbia; Broken Hill, New South Wales; and Waihi, New Zealand.
Separate chapters trace developments in each area, focussing on the emergence of organised labour, the growth of mining companies and the sophistication of mining operations. These underline the need to consider diverse themes, maintaining that the mining industry's pattern of growth can be understood only by adopting such a broad approach. Following the three case studies, the final chapters of the dissertation offer a comparative analysis of Rossland, Waihi and Broken Hill. The study emphasises the similarities of these three communities, especially the cycle of growth, and identifies a crucial common denominator.
Despite differences in climate, in the type and nature of the ore deposit and in the scale of mining activity, all three areas experienced a common trajectory of initial boom followed by subsequent retrenchment. The changing character of the resource base forced this fundamental alteration of productive relations. In each region, the mineral content of the ore declined as the mines went deeper. In addition, with depth the ore tended to become more difficult to treat. Faced with a decline in the value of the product of their mines, companies had to adopt sweeping changes in order to maintain profitable operations. This re-structuring was accomplished in a variety of ways, but the most significant factors, common to Rossland, Broken Hill and Waihi, were the heightened importance of applied science and economies of scale. Both developments underlined the growing importance of the mining engineer and technological innovations, principally in milling and smelting operations. In addition, new non-selective extractive techniques reduced the significance of skilled underground labour.
The re-structuring of the industry not only had similar causes but also had a similar effect. The comparative chapter on labour relations, for example, argues that these managerial initiatives were closely associated with militant episodes in each community. While the leading companies in Rossland, Waihi and Broken Hill successfully reduced their working costs, they all faced the same ultimate end. Their long-term success or failure reflected the skill with which they coped with the inevitable depletion of their ore body.
The common experience of Rossland, Waihi and Broken Hill demonstrates the importance of placing colonial development within a larger context. Regional historians should make greater use of the comparative approach, rather than continuing to focus on the unique and the particular.Arts, Faculty of

Full textAbstract:
This study reports the discovery of a suite of primary lead bromine-substituted chlorides and bromine-iodine substituted oxy-hydroxychlorides which have subsequently exsolved from a sulfogen melt. The implications are that halogens have substituted into sulfide ores at peak metamorphic conditions, during partial melting and exsolved.They provide a direct view of the chemical evolution of the Broken Hill partially melted ore system and may be used as an indicator of coeval melting. The presence of halogens and low melting point chalcophile elements (LMCEs) in these ores suggest that they were introduced together and are a protolith feature. It appears that halogens in the Broken Hill ore deposit were associated with the ores from the outset. Partial melting, melt residue fractionation, enrichment and subsequent mobilisation is predicted. Lead halide compounds have been found in other styles of mineralisation such as Cannington Pb-Zn-Ag ore deposit in NW Queensland and the magmatic Merensky Reef, Bushveld layered complex, South Africa. The highest halogen concentrations recorded in the Broken Hill ore deposit are also confined to the coarse-textured pegmatitic galena. This suggests, that the galena host and a suite of lead halides, represent a bulk composition or final fractionate of a sulfide melt preserved in the post-metamorphic ore deposit at Broken Hill. The halogens have affectively lowered the melting point of the ores at Broken Hill, allowing exsolution of lead halide exsolution lamellae and halide-bearing compounds. A high halogen solubility in galena at regional metamorphic temperatures of ~800{u00B0}C, is a prerequisite for a lowered eutectic. Observed eutectic intergrowth textures, globular textures and low dihedral angle relationships in the ores provide cogent evidence of melting and likely coexisted with an immiscible silicate melt at Broken Hill. Halogen fractionation and partitioning between silicates and sulfides is modeled. Remobilization of massive sulfide orebodies may result from the process of in situ partial melting and liquidus undercooling. Indeed, the lode pegmatite and sulfide ore lithologies at Broken Hill are considered coeval. Halogens are also recorded in the ores of the regional Thackaringa-type deposits of the Consols and Junction Mine lodes. This style of mineralisation is modelled as melt derived. Geochemical and isotopic links are made between the Broken Hill ore deposit and the Thackaringa-type deposits through mobilisation of (LMCEs) and halogens, via F{u2084} fault conduits. The economic implications for partial melting of both styles of mineralisation are profound. Previous experimental work by Mavrogenes et al. (200I), Frost et at. (2002), Kalinowski (2002), Sparks and Mavrogenes (2005) and Wykes and Mavrogenes (2005) provide evidence that partial melting of sulfides occurred. Experimental work in this thesis demonstrates that the solubility of galena in a lead sulfide-halide melt ' sulfogen melt' increases with temperature at a constant pressure of 5 kbar. The behaviour of PbCI{u2082}-PbI{u2082}-PbBr{u2082}-PbS mixtures under high Pressure Temperature define an identifiable eutectic, cotectic relationships as low as 200{u00B0}C, which are well below peak metamorphism conditions of 800{u00B0}C and 5 kbar at Broken Hill. This demonstrates that it is possible for halogen-bearing ore to partially melt and to persist to temperatures well below peak metamorphic conditions. One single experiment performed herein has determined significant melting point depression of pure galena. A general relationship between temperature increase and dissolution of galena into melt above the solidus is established. Melting the PbCl{u2082}-PbI{u2082}-PbBr{u2082}-PbS mixture experimentally suggests a general increase in grain size and in increase in halogen concentration within coarse-grained pegmatitic galena at Broken Hill. The coarse-grained pegmatitic galena is modeled as a product of fractionated and evolved high temperature melts. Thus sulfide melts will accumulate in areas of highest temperatures. A correlation between morphology, temperature and halogen content is established. The Pressure Temperature conditions which formed solid solutions of lead halide and galena phenocrysts in both natural and experimental systems are equivalent. Therefore metamorphic sulfide melting at Broken Hill is fundamentally and theoretically proven to have taken place.

Secondary minerals, formed at low temperature, are the product of the oxidation of primary sulphide ore bodies. The formation and mineralogy of oxidized zones, which phases are stable and which are not, and how toxic heavy metals become incorporated into the crystal structures of the constituent minerals have implications for the heavy metal mobility in the environment and in the disposal of heavy metal and the remediation of contaminated sites This thesis presents an inverstigation of the the crystal chemistry of a suite of Cd, Pb, Zn, Cu, Se and As oxysalt minerals from Broken Hill, NSW; the new mineral species plimerite, nyholmite, liversidgeite and edwardsite, as well as gartrellite, munakataite, osakaite and cadmian serpierite. Crystal structures were studied using single-crystal X-ray diffraction data, in conjunction with the results from electron microprobe analysis, powder X-ray diffraction, infrared absorption spectroscopy, Raman spectroscopy and Mössbauer spectroscopy. The crystal structures are classified according to the mode of polymerization of strongly bonded coordination
polyhedra: chains, sheets or frameworks. The chemical compositions of the minerals and their stabilities are discussed in terms of a combinination of hierarchical ordering, bond-valence theory and the valence-matching principle. For the first time in natural minerals, extensive solid solutions involving cadmium have been observed. Solid solutions between Cd and Zn (in nyholmite), Cd and Ca (in serpierite), and Cd and (Pb+Ca) (in sampleite-lavendulan-zdenekite and conichalciteduftite)
are examined. The minerals examined in this study have implications for the mobility of heavy metals in the environment and in remediation of heavy metal contaminated sites.Thesis (Ph.D.) -- University of Adelaide, School of Earth and Environmental Sciences, 2010

Full textAbstract:
Lead contamination is one of an extensive list of chronic environmental hazards
which are being faced by an increasing number of communities worldwide. The
potential biophysical effects of young children's exposure to relatively low levels of
lead are widely recognised. In response to this awareness, policies and programs are
being designed and implemented with the aim of reducing potential lead exposure.
In addition to their significance for children's biophysical health, the success of these
policies also have implications for the well-being of the children, families, and
communities involved. This thesis argues that an understanding of the ways in which
communities respond to environmental lead contamination is important for the
development and implementation of appropriate interventions.
This thesis examines community responses to chronic environmental lead
contamination in Broken Hill, Australia, a community which is also dealing with
mining industry retrenchments. It examines the nature of cognitive and behavioural
coping responses, and the resulting effects on the health and well-being of the
community and community members. It also examines how responses to the
retrenchments interact with the community responses to lead contamination in a
cumulative manner, and how mediating factors interact with the community response
process. In order to shed light on this complex process, this interdisciplinary study
draws together environmental stress and coping, social impact assessment, public
health, and community responses to environmental contamination theory.
Fieldwork conducted over nine months during six visits included the use of
participant observation and in-depth interviews with parents with young children,
retrenched workers and their families, and other Broken Hill residents. Interviews
were also held with representatives of organisations. The research method proved to
be useful for meeting the research aim, and for respecting research participants and
the sensitive nature of the research topic. After becoming aware of the lead contamination, community members responded
with cognitive minimisation of the lead contamination threat, containment of the
threat to the family level, predominant use of private rather than public responses,
and individual rather than collective coping strategies. The lead contamination,
mediated by this coping process, had the effect of increasing stress and stigma for
parents and families of young children most directly affected, reducing stress and
stigma for other community members, increasing cooperation between local
organisations, and weakening of community social networks.
This process was mediated by the characteristics of the contaminant, characteristics
of individuals, aspects of the social setting, and responses of organisations. The
nature of the lead contamination, and individual residents' perceptions of its
controllability interacted with the community response process. The aspects of the
social setting which affected the community response process are cultural
assumptions, beliefs and values, stigma, relationships between the mining company
and the community, social support and undermining, social influence, and economic
factors. Responses of organisations, including intervention programs, were also
important. Responses to the mining retrenchments interacted within the community
response process.
A model of community responses to chronic environmental lead contamination in
Broken Hill is developed. This thesis argues that health policy needs to focus on
positive health and well-being, and should be guided by three principles- a focus on
the community rather than individual and family levels, the aim of supporting
parents, and communication. Such a reoriented approach will support the efforts of
communities and community members to cope with chronic environmental lead
contamination in an effective and equitable manner.

Abstract The Cadia district of New South Wales contains four alkalic porphyry Au-Cu deposits (Cadia East, Ridgeway, Cadia Hill, and Cadia Quarry) and two Cu-Au-Fe skarn prospects (Big Cadia and Little Cadia), with a total of ~50 Moz Au and ~9.5 Mt Cu (reserves, resources, and past production). The ore deposits are hosted by volcaniclastic rocks of the Weemalla Formation and Forest Reefs Volcanics, which were deposited in a submarine basin on the flanks of the Macquarie Arc during the Middle to Late Ordovician. Alkalic magmatism occurred during the Benambran orogeny in the Late Ordovician to early Silurian, resulting in the emplacement of monzonite intrusive complexes and the formation of porphyry Au-Cu mineralization. Ridgeway formed synchronous with the first compressive peak of deformation and is characterized by an intrusion-centered quartz-magnetite-bornite-chalcopyrite-Au vein stockwork associated with calc-potassic alteration localized around the apex of the pencil-like Ridgeway intrusive complex. The volcanic-hosted giant Cadia East deposit and the intrusion-hosted Cadia Hill and Cadia Quarry deposits formed during a period of relaxation after the first compressive peak of the Benambran orogeny and are characterized by sheeted quartz-sulfide-carbonate vein arrays associated with subtle potassic, calc-potassic, and propylitic alteration halos.
