Hearon, IV Thomas E. "Analysis of salt-sediment interaction associated with steep diapirs and allochthonous salt| Flinders and willouran ranges, south australia, and the deepwater northern gulf of Mexico." Thesis, Colorado School of Mines, 2014. http://pqdtopen.proquest.com/#viewpdf?dispub=3602617.
Повний текст джерелаThe eastern Willouran Ranges and northern Flinders Ranges, South Australia contain Neoproterozoic and Cambrian outcrop exposures of diapiric breccia contained in salt diapirs, salt sheets and associated growth strata that provide a natural laboratory for testing and refining models of salt-sediment interaction, specifically allochthonous salt initiation and emplacement and halokinetic deformation. Allochthonous salt, which is defined as a sheet-like diapir of mobile evaporite emplaced at younger stratigraphic levels above the autochthonous source, is emplaced due to the interplay between the rate of salt supply to the front of the sheet and the sediment-accumulation rate, and may be flanked by low- to high-angle stratal truncations to halokinetic folds. Halokinetic sequences (HS) are localized (<1000 m) unconformity-bound successions of growth strata adjacent to salt diapirs that form as drape folds due to the interplay between salt rise rate (R) and sediment accumulation rate (A). HS stack to form tabular and tapered composite halokinetic sequences (CHS), which have narrow and broad zones of thinning, respectively. The concepts of CHS formation are derived from outcrops in shallow water to subaerial depositional environments in La Popa Basin, Mexico and the Flinders Ranges, South Australia. Current models for allochthonous salt emplacement, including surficial glacial flow, advance above subsalt shear zones and emplacement along tip thrusts, do not address how salt transitions from steep feeders to low-angle sheets and the model for the formation of halokinetic sequences has yet to be fully applied or tested in a deepwater setting. Thus, this study integrates field data from South Australia with subsurface data from the northern Gulf of Mexico to test the following: (1) current models of allochthonous salt advance and subsalt deformation using structural analysis of stratal truncations adjacent to outcropping salt bodies, with a focus on the transition from steep diapirs to shallow salt sheets in South Australia; and (2) the outcrop-based halokinetic sequence model using seismic and well data from the Auger diapir, located in the deepwater northern Gulf of Mexico. Structural analysis of strata flanking steep diapirs and allochthonous salt in South Australia reveals the transition from steep diapirs to shallowly-dipping salt sheets to be abrupt and involves piston-like breakthrough of roof strata, freeing up salt to flow laterally. Two models explain this transition: 1) salt-top breakout, where salt rise occurs inboard of the salt flank, thereby preserving part of the roof beneath the sheet; and 2) salt-edge breakout, where rise occurs at the edge of the diapir with no roof preservation. Shear zones, fractured or mixed `rubble zones' and thrust imbricates are absent in strata beneath allochthonous salt and adjacent to steep diapirs. Rather, halokinetic drape folds, truncated roof strata and low- and high-angle bedding intersections are among the variety of stratal truncations adjacent to salt bodies in South Australia. Interpretation and analysis of subsurface data around the Auger diapir reveals similar CHS geometries, stacking patterns and ratios of salt rise and sediment accumulation rates, all of which generally corroborate the halokinetic sequence model. The results of this study have important implications for salt-sediment interaction, but are also critical to understanding and predicting combined structural-stratigraphic trap geometry, reservoir prediction and hydrocarbon containment in diapir-flank settings.

Повний текст джерелаMany regional disconformities or 'sequence boundaries' have now been identified throughout the late Proterozoic Wilpena sediments of the Adelaide Geosyncline, South Australia. The most prominent of these appears near the base of the Wonoka Formation and has been related to the formation of incised valleys or 'canyons'. Early interpretations of these canyons suggested they were of submarine origin, cut and filled in a deepwater environment. However, more recent work has focused on a subaerial model whereby the incisions were cut fluvially. Work was carried out on the Waukarie Creek Canyon Complex in the Southern Flinders Ranges. Observations gained from field mapping tend to favour a subaerial origin for canyon development. Some localities were found that provide evidence that there was some tectonic activity, expressed by deformation of sediments, prior to the formation of the Wonoka canyons. Palaeocurrents from flute casts and current ripples show that numerous reversals were found throughout the canyon, substantiating a tectonic influence on the formation of the canyons. This activity may be approximately coeval with the Beardmore Orogeny of Antarctica. The compressional Cambro-Ordovician Delamerian Orogeny subsequently deformed the sedimentary prism in a complex array of north-south trending tight folds and reverse faults.

Повний текст джерелаPrevious investigations into the Ediacara Member of the late Proterozoic Rawnsley Quartzite in the Flinders Ranges have produced differing interpretations of the depositional environment. Studies at Nilpena Hills indicate that deposition was influenced by back barrier lagoonal conditions with the intermittent influx of fluidised sands which mantled lagoonal muds. Re-interpretation of the Ediacara assemblage shows a hitherto unrecognised benthonic bias. This abundance of sessile, benthonic forms supports a sub-tidal depositional environment. However, the increase in the numbers of motile forms compared with sessile forms, preserved towards the top of the member, accords well with one of two inferred shallowing upward cycles within the sequence. A recent re-evaluation of the nature of the Precambrian-Cambrian boundary in the Flinders Ranges suggests a conformable relationship between the Pound Subgroup and the overlying Early Cambrian beds. This is at odds with previous interpretations, which proposed that a regional disconformity occurs at the boundary. Mapping at Mt. Scott Range, Puttapa Syncline and Red Range provided ample evidence that several periods of at least partial lithification occurred within the Pound Subgroup, before the onset of Cambrian deposition. Erosive downcutting marks the contact of the Pound Subgroup-Uratanna Formation at Mt. Scott Range, Red Range and Puttapa Syncline. Erosive downcutting of the Parachilna Formation into the Uratanna Formation was mapped at Mt. Scott Range. The Pound Subgroup-Parachilna Formation contact was mapped as a disconformity which becomes a high angle unconformity near the Beltana Diapir.

Повний текст джерелаThis study creates three regolith-landform maps of the Paralana Creek catchment on the north-eastern margin of the Flinders Ranges using three readily available remotely sensed data types: a 2D digital elevation model, an airborne gamma ray radiometric response image, and a QuickBird satellite image, each method providing data about different aspects of the landscape. The regolith-landform map based on the digital elevation model provided an overview of the major landforms, with a basic understanding of the regolith and landform types. The regolith-landform map based on the airborne radiometric image provided data about the concentration and distribution of radioelements within the landscape, as well as a basic understanding of regolith and landform types and processes within the study area. The regolith-landform map based on the QuickBird image provided the most data about the regolith-landform units of the area, as well as current and previous landscape processes and evolution. Using these remote sensing methods this study created three regolith-landform maps, as well as identifying regolith-landform units, how landforms affect regolith type, distribution and succession, along with radioelement composition, transport and distribution within the study area. Map interpretation used the understanding of the landscape gained from all three maps in combination.

Повний текст джерелаThe widespread shrub species Eremophila freelingii, of inland Australia, has successfully expressed elevated U contents in both leaf and twig samples at workings of known mineralisation in the Mt. Painter region, South Australia. Leaf material produced reasonable contrast in U concentrations and good success rate at expressing buried mineralisation with approximately 75 of all samples returning a U concentration greater than or equal to analytical detection limit (DL). A comparison of leaf with twig material from E. freelingii makes this study unique. Elements generally occur in higher concentration in twig tissues than leaves, although twigs have a greater tendency to host detrital (dust) inputs. The highest U concentration came from the high-grade historic Hodgkinson U-prospect (0.25% U3O8). Overall leaves contained 0.05 – 0.24 ppm U and twigs contained 0.08 – 0.41 ppm U (1.04-5.86 times higher). Twigs also hosted Re up to 266 times the DL when leaves produced values below the DL. Re elevations in leaf tissue is characteristic of the intrusive granites; Pinnacles and Needles. Beryllium is also unique to Hodgkinson and the Pinnacles and Needles sites. A few traditional U pathfinder elements have an association with U in plant tissues including; Y, Ce, La on a regional scale, and more exclusively at Four Mile West. Other elements; Li and Be displayed associations with U in twigs limited to the Hodgkinson prospect. Mineralisation in the Four Mile West sequence occurs in the Eyre Formation (Four Mile U-prospect) and in the Namba Formation (Beverley U deposit). E. freelingii displays elevations in U situated over these units at concentrations above the regional biogeochemical average. Other popular commodities, Au and Ag, were present in low concentrations and returned values ≥ DL in 25.3% and 57.8% of all samples respectively. The Four Mile West sequence hosts the highest Au concentrations, while the hematite breccias host the elevated Ag results. Elevated Zn concentrations are also characteristic of the hematite breccias. Copper showed high variation (3.12 – 32.02 ppm) in all samples but these results do not appear to be closely associated with geological setting. The wide range of element accumulation E. freelingii is able to display would stimulate further research with this species in biogeochemical exploration.

Повний текст джерелаThe origin of small manganese deposits from the central Southern Flinders Ranges, has not previously been adequately discussed. The region comprising these sedimentary manganese accumulations incorporates a sinuous folded sequence of thick variegated clastic and carbonate sediments deposited within the Adelaide Geosyncline, the stratotype basin for the Adelaidean sediments delineated. Extended exposure of the craton to the west provided a dominant source of both sedimentary detritus and manganese ore constituent. Paragenesis involved leaching of manganese from this source region, transport into the aqueous system and subsequent precipitation in favourable shallow-marine environments meridionally within the Adelaide Geosyncline. Cyclic eustatic fluctuations increased potential ionic manganese concentration, with remobilization and concentration during transgressive oxygen deficient phases and oxidation and precipitation during alternate regressive more oxygenated phases. The precipitation of particulate manganese-oxides, from pre-existing particulate and dissolved manganese from an enriched reservoir, was controlled by the interactive responses of a number of features: estuarine circulation, anoxic-oxic water stratification, and sediment-water interface relationships, at specific geomorphological sites on a stable shallow-marine continental platform. Retention of the precipitated manganese resulted from rapid burial by regressive sands and silts, with little post-genetic supergene alteration of the deposit observed.

Повний текст джерелаThe Elatina Formation is exposed in outcrops throughout South Australia, most notably represented by distinct glaciogenic deposits in central and northern Flinders Ranges. As the formation reflects low latitude glaciation, it has previously been used as a benchmark study in the development of the Snowball Earth hypothesis. Pichi Richi Pass in the central Flinders Ranges is an excellent example of the Elatina Formation, however significant uncertainties exist regarding the local sequence stratigraphy and interpretation of the depositional environments. A detailed facies analysis and 3D model of the Elatina Formation at Pichi Richi Pass was established to demonstrate the variability and distribution of the depositional system. The Elatina Formation consists of four lithostratigraphic units, with eight facies identified within two of the units. The facies were established from lithological properties, and then associated based on descriptions and interpretation of their depositional processes. The results reflect thick non-glaciogenic layers interbedded with thin glaciogenic layers. The non-glaciogenic layers were deposited in coastal, deltaic and fluvial settings, while the glaciogenic units were deposited in a glaciofluvial environment. As most of the Elatina Formation in Pichi Richi Pass appears to be deposited under moving water, it suggests that the palaeoenvironment of the Elatina Formation is not consistent with prolonged glacial conditions like that of Snowball Earth. Rather, it denotes variable glacial periods characterised by glacial advance and retreat.

Повний текст джерелаThe coincidence between the timing of the subsidence of a trough-like structure adjacent to Wilpena Pound and the initiation of canyons associated with the late Proterozoic Wonoka Formation in other parts of the Flinders Ranges provides circumstantial but not necessarily compelling evidence for a tectonic control being involved with the formation of the canyons. The trough, here termed The Wilpena Trough, is characterised by the presence of a deep central sag and shoulder sags bounded by steep north-easterly trending faults. Other canyons may have marginal faults; and the numerous reversals of current indicators within them, rather than simple unidirectional current trends as expected with turbidite erosion, substantiate a tectonic influence in their generation. Small scale faulting in the Wearing Dolomite Member of the Wonoka Formation reflects the dominantly extensional regime in which the Wilpena Trough was formed. A phase of warping prior to deposition of the Wonoka Formation may have provided the necessary trigger to produce stress zones in strata, where growth faults controlling the sedimentation in the Wilpena Trough were initiated. After deposition of the Wearing Dolomite Member in a shallow water palaeoenvironment, Units 2 and 3 of the Wonoka Formation were deposited in deeper water settings on a shelfal slope. This idea supports a submarine environment prior to subsidence of the Trough. Measured stratigraphic thickness changes give a precise timing for the initiation of fault movement that caused thickened packages of sediments. Major fault movement and corresponding sediment subsidence became active near the Unit 2/Unit 3 transition and dominated the deposition of Unit 3 through to Unit 7. Units 4 to 9 represent a wedge of prograding shelf sediments. Unit 10 is a shallow transgressional sequence and a sequence boundary has been proposed of the base of this unit, due to the marked change in sedimentary style. Stable carbon and oxygen isotope data from the sediments of the Wonoka Formation in the central Flinders Ranges shows an initial low negative plot which is succeeded by an interval showing a strong negative excursion which then makes a shift back to low negative values. A possible correlation between the late Proterozoic units in the Adelaide Fold Belt and the eastern Officer Basin enables the data from the Wonoka Formation to be added to information which Pell (1989) obtained from the Rodda Beds to show a continuous trend from the negative excursion to a broad positive one. Comparison with the corresponding overseas data provides a potential tool for late Proterozoic inter-regional basin correlation.

Повний текст джерелаCarbon, oxygen and strontium isotope stratigraphy has increased the resolution of Proterozoic stratigraphic correlation. Isotopic analysis was performed on the late Proterozoic Wonoka Formation canyon and carbonate platform sequences. Highly depleted and homogenised carbon and oxygen isotopes characterise the canyon fill (13C = -8 to -7%o, (18O = - 17 to -15%o PDB ) whilst a major positive excursion was observed in the Wonoka Formation carbonate platform sequence ((13C = -8 to -0.5%o, (18O = -15.0 to -7.0%o PDB). These values correlate closely with other established isotopic trends throughout the Adelaide Geosyncline. However, similar aged late Vendian strata throughout the world show low positive values. Strontium isotopic analysis revealed relatively 87Sr enrichment in the carbonate platform deposits compared to the canyon sequence. This was attributed to the input of 87Sr enriched terrestrially derived strontium. The 87Sr/86Sr ratio of the Wonoka Formation correlates closely with established late Proterozoic seawater trends. Therefore, a primary strontium isotopic composition is implied for the Wonoka Formation. Major and trace element geochemical analysis (Ca, Mg, Sr, Fe, Mn, and Rb) was performed to assess the diagenetic alteration of the late Proterozoic strata. Samples with low Mn/Sr, high Ca/Sr, high strontium, and low rubidium have the highest probability of preserving a primary geochemical signal. Most samples from the Pichi Richi region analysed plotted under the altered Mn/Sr (<2) and Ca/Sr (<2000) values. The high remnant strontium-concentrations of the Wonoka Formation suggest neomorphism from an aragonitic precursor. Micritic carbonate of the Wonoka Formation was probably a primary marine precipitate of aragonite derived from late Proterozoic supersaturated seas. Therefore, the majority of sediment diagenesis probably occurred in the marine phreatic zone, resulting in the observed primary isotopic composition.

Повний текст джерелаThe Mount Painter Province in the Northern Flinders Ranges, South Australia is composed of Palaeoproterozoic to Mesoproterozoic basement overlain by 7-12 kilometres of Neoproterozoic to Cambrian sedimentary rocks and is associated with high lateral geothermal gradients. During the Early Paleozoic, deformation and metamorphism reached greenschist to amphibolite facies during the ~500 Ma Delamerian Orogeny. This study focuses on the subsequent thermal history of the area by studying an E-W profile through the Mount Painter Province using the widely used techniques of structural mapping, micro-structural analysis and 40Ar/39Ar thermochronology to characterise and date deformation and cooling (as a proxy for exhumation). The E-W trending profile, known as the Hamilton Fault, is south dipping oblique slip with a normal and dextral component overprinted by younger brittle structures and brecciation which is seen in the structural and micro-structural analysis.. It is proposed to have a very active past and there is evidence of movement in the Adelaidean due to an apparent formation offset of ~600 m. The regional context of the Hamilton Fault having a dextral and normal component suggests an ε3 uplift, an ε2 extension SW to NE and ε1 NW-SE shortening. This is similar in character to the N-S shortening which is seen in the Alice Springs Orogeny (ASO). Results from the 40Ar/39Ar thermochronology show the basement metasedimentary rocks have cooling ages of around ~350 Ma between 300 to 400 °C and 312 Ma at 150 °C. Interestingly, the younger Adelaidean metasedimentary rocks have an older cooling age of 390 Ma between 300 to 400 °C. The thermochronology data suggests differential cooling has occurred. The observations suggest that exhumation is driven following the Delamerian folding event and forced the earlier cooling of shallower samples at a slower rate and later cooling of the deeper samples at a faster rate, a process caused by differential tilting. The cooling paths are well represented in this example as shown by converging cooling paths. Overall I attribute this subsequent thermal history and structural similarity to the ASO, a major widespread dramatic orogenic event which has not been widely recognized as a significant tectonic event in the Adelaide Fold Belt.
