Full textAbstract:
The intracratonic Officer Basin of central Australia was formed during the Neoproterozoic, approximately 820 m.y. ago. The eastern third of the Officer Basin is in South Australia and contains nine unconformity-bounded sequence sets (super-sequences), from Neoproterozoic to Tertiary in age. Burial history is interpreted from a series of diagrams generated from well data in structurally diverse settings. These enable comparison between the stable shelf and co-existing deep troughs. During the Neoproterozoic, subsidence in the north (Munyarai Trough) was much higher than in either the south (Giles area) or northeast (Manya Trough). This subsidence was related to tectonic as well as sediment loading. During the Cambrian, subsidence was much higher in the northeast and was probably due to tectonic and sediment loading (carbonates over siliciclastics). During the Early Ordovician, subsidence in the north created more accommodation space for the last marine transgression from the northeast. The high subsidence rate of Late Devonian rocks in the Munyarai Trough was probably related to rapid deposition of fine-grained siliciclastic sediments prior to the Alice Springs Orogeny. Rates of subsidence were very low during the Early Permian and Late Jurassic to Early Cretaceous, probably due to sediment loading rather than tectonic sinking. Potential Neoproterozoic source rocks were buried enough to reach initial maturity at the time of the terminal Proterozoic Petermann Ranges Orogeny. Early Cambrian potential source rocks in the Manya Trough were initially mature prior to the Delamerian Orogeny (Middle Cambrian) and fully mature on the Murnaroo Platform at the culmination of the Alice Springs Orogeny (Devonian).

Full textAbstract:
The Amadeus Basin is divided into a number of structural provinces that developed during the Palaeozoic Alice Springs Orogeny, the course of which is described in terms of: Early Palaeozoic preorogenic crustal extension and basin development; Late Ordovician-Carboniferous NE-SW compressional orogenesis; and Late Carboniferous-(?)Early Permian NW-SE compression.The Southern Province is composed largely of Proterozoic formations that had been deformed during the Petermann Ranges Orogeny. The Central Anticlinal Province is a shear zone of four en echelon trends. The Parana Hills and Mereenie trends have a left lateral orientation to each other and formed during the first phase of orogenesis; the Gardiner Range and James Range trends are right lateral and formed during the second stage. Structures in the Northern Province were created by decollement within the evaporite-bearing Bitter Springs Formation and, to a lesser extent, in the Cambrian Chandler Formation, and by collapse of the basin fill under the burden of the Brewer Conglomerate in a style similar to the formation of diapirs along the northern front of the Pyrenees. The MacDonnell Homocline is a mountain front tip line that resembles the Triangle Zone of the Canadian Rocky Mountains. The Allambi Thrust Zone separates the Northern Province from the Camel Flat Platform that bears diapiric salt walls derived from the Chandler Formation.The varying stress field and revised time scale for orogeny may be of significance to evaluation of reservoir fracture patterns and source rock maturation curves.

Full textAbstract:
Apatite Fission Track Analysis (AFTA) combined with maturity data has revealed that four (possibly five) cooling events affected the northern margin of the Amadeus Basin since the Early Carboniferous. A consistent regional thermal history framework is developed, with recognition of cooling events beginning in the Carboniferous/Early Permian (between ~360 and 290 Ma), the Early Jurassic (~200 Ma), Late Cretaceous (between ~80 and 70 Ma) and Tertiary (between ~ 25 and 20 Ma). We suggest the first of these reflects uplift and erosion associated with the Alice Springs Orogeny, while Early Jurassic cooling reflects uplift and erosion associated with the Fitzroy Movement. Uplift and erosion in the Late Cretaceous probably relates to the breakup of Australia and Antarctica (opening of the Tasman Sea) at about this time. Later uplift and erosion in the Miocene may reflect Neogene collision of the Australian and SE Asian Plates in the region of the Banda Arc.In Tyler–1 (northern Amadeus Basin), maturation modelling using paleotemperature constraints from AFTA and VR equivalent data suggests the main source rock horizon (Ordovician Horn Valley Siltstone), went through the dry gas window during burial associated with the latter stages of the Alice Springs Orogeny. Basinward (south) of this foreland wedge, the influence of Devonian-Carboniferous loading decreases enabling oil expulsion from the Horn Valley Siltstone to have charged the Mereenie Structure. This was later partially displaced by gas.To date the Neoproterozoic sequences have yielded only dry gas (at Dingo field, Ooraminna–1 and Magee–1) which could be due to original source rock characteristics, but more likely to high maturity levels in the main depocentres. Previous notions that the Ordovician petroleum system was probably only active in the northern portion of the basin appear correct, but gas charged traps at the level of the Neoproterozoic should be ubiquitous.

Full textAbstract:
The Neoproterozoic to Late Paleozoic-aged Amadeus Basin is a large (~170 000 km2) east–west-trending basin, bounded to the south by the Musgrave Province and to the north by the Arunta Block of the Northern Territory. Commercial oil and gas production is established in the northern part of the basin but the southern part is still a frontier exploration area. Vintage and new seismic reflection data have been used with well data along the south-eastern Amadeus Basin to construct a new structural and depositional model. Three major phases of deformation controlling deposition have been identified. The first phase is characterised by a SW–NE trending structural fabric and is thought to be older than the deposition of the first sediments identified above basement (Heavitree and Bitter Springs formations). The second phase corresponds to the Petermann Orogeny (580–540 Ma) and trends in a NW–SE orientation. The third phase is the Alice Springs Orogeny (450–300 Ma) and is oriented W–E to WNW–ESE in this part of the basin. This tectono-stratigraphic model involving three distinct phases of deformation potentially explains several critical observations: the lack of Heavitree reservoir at Mt Kitty-1, limited salt movements before the Petermann Orogeny (~300 Ma after its deposition) and salt-involved structures that can be either capped by the Petermann Unconformity and overlying Cambrian to Devonian sediments, or can reach the present day surface. Finally, this model, along with availability of good quality seismic data, opens new perspectives for the hydrocarbon exploration of the Amadeus Basin. Each of the tectonic phases impacts the primary petroleum system and underpins play-based exploration.

Full textAbstract:
The Georgina Basin is an intracratonic basin on the central-northern Australian craton. Its southern portion includes a highly prospective Middle Cambrian petroleum system which remains largely unexplored. A plethora of stratigraphic names plagued previous exploration but the lithostratigraphy has now been rationalised using previously unpublished electric-log correlations and seismic and core data.Neoproterozoic and Lower Palaeozoic sedimentary rocks of the southern portion of the basin cover an area of 100,000 km2 and thicken into two main depocentres, the Toko and Dulcie Synclines. In and between these depocentres, a Middle Cambrian carbonate succession comprising Thorntonia Limestone and Arthur Creek Formation provides a prospective reservoir-source/seal couplet extending over 80,000 km2. The lower Arthur Creek Formation includes world class microbial source rocks recording total organic carbon (TOC) values of up to 16% and hydrocarbon yields up to 50 kg/tonne. This blanket source/seal unconformably overlies sheetlike, platform dolostone of the Thorntonia Limestone which provides the prime target reservoir. Intra- Arthur Creek high-permeability grainstone shoals are important secondary targets.In the Toko Syncline, Middle Cambrian source rocks entered the oil window during the Ordovician, corresponding to major sediment loading at this time. The gas window was reached prior to structuring associated with the Middle Devonian-Early Carboniferous Alice Springs Orogeny, and source rocks today lie in the dry gas window. In contrast, high-temperature basement granites have resulted in overmaturity of the Arthur Creek Formation in the Dulcie Syncline area. On platform areas adjacent to both these depocentres source rocks reached peak oil generation shortly after the Alice Springs Orogeny; numerous structural leads have been identified in these areas. In addition, an important stratigraphic play occurs in the Late Cambrian Arrinthrunga Formation (Hagen Member) on the southwestern margin of the basin. Key elements of the play are the pinchout of porous oil-stained, vuggy dolostone onto basement where top seal is provided by massive anhydrite while underlying Arthur Creek Formation shale provides a potential source.

Full textAbstract:
Recent petroleum exploration in EP 186 and EP 187 in the north-western Officer Basin has greatly increased knowledge of the regional stratigraphy, structure and petroleum prospectivity of the region. This exploration programme has involved the drilling of two deep stratigraphic wells (Dragoon 1 and Hussar 1) and the acquisition of 1438 km of seismic data. Integration of regional gravity and aeromagnetic data with regional seismic and well data reveals that the Gibson Sub-basin primarily contains a Proterozoic evaporitic sequence. In contrast, the Herbert Sub-basin contains a Late Proterozoic to Cambrian clastic and carbonate sequence above the evaporites. This sequence, which was intersected in Hussar 1, is identified as the primary exploration target in the Western Officer Basin. The sequence contains excellent reservoir and seal rocks in association with mature source rocks. Major structuring of the basin has also been caused by compressive movements associated with the Alice Springs Orogeny. The northwestern Officer Basin thus has all of the ingredients for the discovery of commercial hydrocarbons.

This item is only available electronically.The Arunta Inlier preserves a complex structural history, subject to a series of igneous, metamorphic and deformational events from the Paleoproterozoic to the mid-Paleozoic. U-Pb detrital zircon ages from Paleoproterozoic and Neoproterozoic sediments at Ormiston Gorge coincide with the timing of various tectonic phases in the Arunta Inlier. First order interpretations suggest that the Northern Arunta Inlier was the source of the oldest zircons recorded at ~1820 Ma, coinciding with the timing of the Stafford Event. The Strangways Orogeny at ~1770 Ma and 1730 Ma is the earliest deformation preserved in the Central Arunta Inlier and is probably the source of zircons accumulated in these sediments. Zircons post-dating the Strangways Orogeny are likely sourced from the Southern Arunta Inlier, coinciding with the Argilke Tectonic Event at ~1680 Ma, the Chewings Orogeny at ~1600 Ma, the Anmatjira Uplift Phase at 1500-1400 Ma and the emplacement of the Teapot Granite Complex at ~1140 Ma. The Neoproterozoic Heavitree Range Quartzite sediments represent initial deposition in the Amadeus Basin, which forms the remnant of a once much larger intracratonic basin in central Australia known as the Centralian Superbasin. The Arunta Inlier was exhumed from beneath the Centralian Superbasin during the Devonian-Carboniferous Alice Springs Orogeny, forming a series of subbasins including the Amadeus, Ngalia and Georgina Basins. North-south crustal compression during this Orogeny reactivated a series of steep north-dipping Mesoproterozoic fault structures including the Redbank shear zone and the Ormiston thrust zone. The northern Amadeus Basin is characterised by coupled basement and cover deformation, producing a series of basement-rooted south-propagating thrusts, which penetrate the basal Heavitree Range Quartzite. Structural cross-sections constructed across the Ormiston region propose a series of splay thrusts within the Ormiston thrust zone, with the basement and Heavitree Quartzite heavily deformed. The conformably overlying Bittersprings Formation comprises salts and evaporates, interpreted as a detachment layer. 40Ar/39Ar muscovite dating of mylonitic shear zones at Ormiston Gorge have constrained ‘peak deformation’ conditions in the region to a minimum age of 350 ± 3 Ma. Mineral assemblages formed in the surrounding areas reflect greenschist to lower amphibolite facies metamorphism, with temperatures reaching at least 350°C.

Full textAbstract:
This item is only available electronically.The 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.
