Rig Seismic Geophysical and Geological Research Cruise off Western and Southeastern Tasmania

R/V Rig Seismic carried out Bureau of Mineral Resources (BMR) research cruise 78 on the Tasmanian margin from 24 March to 18 April, 1988. The first half of the cruise was devoted to multichannel seismic surveying - 1750 km on the west Tasmanian margin and 265 km off southeast Tasmania. The west Tasmanian seismic survey examined the King Island and Strahan Sub-basins of the Sorell Basin, tested the structure of the continental margin from the continental shelf to undoubted oceaniccrust, and provided a key seismic tie through the thick sedimentary basin on the west Tasmanian continental slope. The southeast Tasmanian seismic survey examined the Palaeozoic sequences near Bruny Island on which oil seeps are known.
The latter half of the cruise was devoted to geological sampling on the west Tasmanian margin. Twelve stations were designed to sample basement and older outcropping sequences (Mesozoic and Palaeogene) to provide control for seismic interpretation. Younger sequences were cored at 37 stations in order firstly, to establish amodel for Cainozoic sedimentation, and secondly, to allow the analysis of surface sediments to define areas of anomalous concentrations of thermogenic gas. Near-surface thermal gradient and thermal conductivity were measured at 10 stations as a means of establishing thermal flux.
The work will enable us to better define the geology of the basins, and especially their history of rifting, their stratigraphy, and their petroleum potential.

Hydrogeochemical Baseline Mapping of the Great Artesian Basin

The first large-scale projects for geological storage of carbon dioxide on the Australian mainland are likely to occur within sedimentary sequences that underlie or are within the Triassic-Cretaceous, Great Artesian Basin (GAB) aquifer sequence. Recent national1 and state2 assessments have concluded that certain deep formations within the GAB show considerable geological suitability for the storage of greenhouse gases. These same formations contain trapped methane and naturally generated CO2 stored for millions of years. In July 2010, the Queensland government released exploration permits for Greenhouse Gas Storage in the Surat and Galilee basins.An important consideration in assessing the potential economic, environmental, health and safety risks of such projects is the potential impact CO2 migrating out of storage reservoirs could have on overlying groundwater resources. The risk and impact of CO2 migrating from a greenhouse gas storage reservoir into groundwater cannot be objectively assessed without knowledge of the natural baseline characteristics of the groundwater within these systems. Due to the phase behaviour of CO2, geological storage of carbon dioxide in the supercritical state  requires depths greater than 800m, but there are few hydrogeochemical studies of these deeper aquifers in the prospective storage areas. Historical hydrogeochemical data are compiled from various State and Federal Government agencies. In addition, hydrogeochemical information is compiled from thousands of petroleum well completion reports in order to obtain more information on the deeper aquifers, not typically used for agriculture or human consumption. The data are passed through a QC procedure to check for mud contamination and to ascertain whether a representative sample had been collected. The large majority of the samples proved to be contaminated but a small selection passed the QC criteria. The full dataset is available for download from GA's Virtual Dataroom.

SA Exploration Initiative - Area A2, SA., 1993 (P700), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the SA Exploration Initiative - Area A (A1-A7), SA., 1993 survey were acquired in 1992 by the SA Government, and consisted of 330915 line-kilometres of data at 400m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Exploring for the Future: South Nicholson Basin Geological summary and seismic data interpretation

Exploring for the Future (EFTF) is a four year $100.5 million initiative by the Australian Government that aims to boost northern Australia's attractiveness as a destination for investment in resource exploration. As part of this program, Geoscience Australia has been tasked with gathering new pre-competitive data and information concerning potential mineral, energy and groundwater resources concealed beneath the surface, on an unprecedented scale. To ensure the program has the greatest impact Geoscience Australia will use innovative techniques in greenfield areas where the resource potential is completely unknown at a semi-continental scale.
A major EFTF output is the acquisition of deep crustal seismic reflection data. The first tranche of this was completed in early August 2017 in the region between the southern McArthur Basin to the Mt Isa western succession, crossing the South Nicholson Basin and Murphy Province. Prior to this survey, the region contained no seismic data and minimal well data. 
This new seismic data will support exploration activities by providing a better understanding of the basin and basement architecture and structural evolution of the region, and assist in identifying geological terrains with resource potential. The preliminary processed data was released at the Annual Geoscience Exploration Seminar in March 2018 (Henson et al., 2018). This record presents the interpreted data alongside a geological summary of the region including the McArthur Basin, South Nicholson Basin and Mount Isa Orogen and provides a baseline for further studies in the region including the identification of a new sub-basin and presentation of current knowledge of the stratigraphy and geochemistry.
The new seismic reflection data acquired over the South Nicholson Basin as part of the Exploring for the Future program has outlined many areas of future opportunity. Geoscience Australia is currently pursuing an exciting program building upon previous work in the region, including extensive geochemical and geochronological studies aiming to build a greater understanding of the stratigraphy imaged by the seismic data. Further, our work in this region has already demonstrated the complicated and poorly understood nature of the stratigraphy and structural relationships within the region.

Reconstructing the tectonic evolution of the Houtman Sub-basin, Western Australia

The Houtman Sub-basin is an under-explored region of the northern Perth Basin, offshore Western Australia. Interpretation of Geoscience Australia’s recently acquired GA349 seismic survey reveals that the northern sub-basin contains a Permian–Early Cretaceous succession up to 16 km thick, dominated by two main phases of extension in the Permian and late Jurassic–Early Cretaceous. The most prominent feature of the basin architecture is a series of large Permian half graben which extend along the inboard part of the basin and are overlain by a westward-thickening Triassic–Jurassic succession with closely spaced faulting in the outboard region. To aid understanding of the basin’s petroleum prospectivity, this study uses 2D structural restorations to investigate the major phases of basin evolution, the amount of crustal extension (ß) associated with each rifting event and the magnitude of uplift and erosion associated with the Valanginian unconformity. 
Newly interpreted seismic sequences were used to construct a 2D geological model on a dip line through the northern Houtman Sub-basin, which formed the basis of the structural restorations. A combination of decompaction and reconstruction using a simple shear kinematic model enabled regional restoration of the basin through time. Constraints on estimates of erosion at the Valangininian unconformity were provided by area balancing. 1D subsidence curves extracted along the section were compared with crustal thickness changes in the restored 2D profile to investigate the variation in extension factor along the transect. 
Results indicate a complex basin history with multiple phases of rifting, culminating in the separation of Australia and Greater India. Initial Early- to mid-Permian rifting was focused along the inboard part of the basin, resulting in the formation of large half-graben and deposition of up to 10 km of synrift sediments. This was followed by widespread Triassic–Early Jurassic thermal subsidence. The second major phase of rifting occurred in the late Jurassic–Cretaceous and saw the focus of deformation shift to the outboard region of the basin. The total ß factor for both phases of extension is &gt;6 over the outboard part of the basin, indicating hyperextension of the crust, with a maximum ß factor of 3 associated with Permian graben formation. The results of this work have important implications for petroleum potential in the basin. Crustal thinning and maximum burial depth are two key factors influencing the basin’s burial and temperature history, and hence are required for predicting source rock maturity and generation history.
