Heavy minerals in the late Cainozoic sediments of southeastern South Australia and western Victoria

Concentrations of heavy minerals in the prograded coastal sequence of southeastern South Australia are generally low, partly as a result of the high content of locally derived biogenic carbonate in many of the sediments. Terrigenous input to the nearshore region appears to have been relatively slight, and the operation of concentrating mechanisms minimal. The highest heavy-mineral concentrations recorded in the area (up to 1.2% total heavies) occur in a sand of probable Pliocene age underlying Quaternary beach and dune deposits. In general, the heavy-mineral suite present in the sediments consists of between 25 and 45 percent magnetite-plus-ilmenite, 5 and 20 percent leucoxene, 5 and 25 percent zircon, 5 and 30 percent tourmaline, and between 0 and 10 percent amphibole, epidote, rutile and garnet. Andalusite, sillimanite, kyanite and staurolite occur as minor components in many assemblages. Sialic igneous, reworked sedimentary, metamorphic and to a slight extent mafic igneous components are present. Probable sources include the igneous rocks of the Padthaway Ridge, metamoraphic and sedimentary rocks of the Fleurieu Peninsula and Kangaroo Island, and older Tertiary sediments. Variations in the suite are defined by cluster and Q-mode factor analysis. Higher concentrations of heavy minerals occur within the older (probably Pliocene) ridges of the western Victorian Murray Basin. These ridges which approximately parallel the southeast South Australian ridge sequence, are siliceous, and commonly contain thin bands of concentrated heavy mineral (up to 20% total heavies in the bands) in the lower part of the Parilla Sand. The suite is mineralogically mature (generally 50-70% opaque, 15-30% tourmaline, 3-5% rutile, 5-15% zircon and 1-3% others) and differs considerably from that present in the southeast South Australian sequence. The difference reflects differences in provenance of the two areas and the probable modification by intrastratal solution of the assemblages originally present in the older deposits.

National ASTER Map Ferrous iron index


Band ratio: B5/B4 Blue is low abundance, Red is high abundance
This product can help map exposed "fresh" (un-oxidised) rocks (warm colours) especially mafic and ultramafic lithologies rich in ferrous silicates (e.g. actinolite, chlorite) and/or ferrous carbonates (e.g. ferroan dolomite, ankerite, siderite). Applying an MgOH Group content mask to this product helps to isolate ferrous bearing non-OH bearing minerals like pyroxenes (e.g. jadeite) from OH-bearing or carbonate-bearing ferrous minerals like actinolite or ankerite, respectively. Also combine with the FeOH Group content product to find evidence for ferrous-bearing chlorite (e.g. chamosite).

Petroleum Systems Modelling for Unconventional Play Analysis in the Cooper Basin

The Cooper Basin is a late Carboniferous - Middle Triassic intracratonic basin in north-eastern South Australia and south-western Queensland. The basin is currently Australia's premier onshore hydrocarbon producing province and hosts a range of unconventional gas play types, including the extensive basin-centred and tight gas accumulations in the Permian Gidgealpa Group, deep dry coal seam gas associated with the Patchawarra and Toolachee formations, as well as the shale gas plays in the Murteree and Roseneath shales.
This study uses petroleum systems modelling as a tool to investigate the prospectivity of each unconventional gas play type across the basin. Existing published structure surfaces were updated to incorporate new seismic and well data interpretations and combined into a regional 3D basin model, ensuring seamless data integration across the state border. All publicly-available total organic carbon (TOC) and RockEval data were compiled and used to review source rock distribution and quality, demonstrating the abundance of viable source rock intervals across the basin. Cooper Basin-specific kinetic relationships allowed the estimation of oil and gas windows. All datasets were integrated into a multi-1D petroleum systems model, which was calibrated using vitrinite reflectance and corrected temperature for 90 wells. Petroleum system model outputs, including thermal maturity and hydrocarbon generation, expulsion and retention maps by source interval, were then used to characterise possible play fairway extents for each play type.
The hydrocarbon generation maps and play fairway areas for the basin centred gas and deep dry coal seam gas plays of the Toolachee and Patchawarra formations highlight that these play types are both more extensive and more prospective than the Roseneath and Murteree shale gas plays. However, the overlapping nature of all three play types makes it more convenient to consider them collectively as a composite Gidgealpa Group unconventional gas play. The composite Gidgealpa Group gas play fairway map shows that the Nappamerri and Allunga troughs are highly prospective, along with the deepest areas of the Patchawarra and Arrabury troughs. Results also indicate prospectivity potential for unconventional gas further to the northeast, including areas of the Windorah Tough and Ullenbury Depression, consistent with recent drilling results. Further potential may exist in shallower coal plays outside the composite resource play area.

Robinson Range Belele Potassium Grid Geodetic

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected 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.
This radiometric potassium grid has a cell size of 0.00083 degrees (approximately 88m) and shows potassium element concentration of the Robinson Range - Belele, WA, 2003 in units of percent (or %). The data used to produce this grid was acquired in 2003 by the WA Government, and consisted of 53021 line-kilometres of data at 400m line spacing and 60m terrain clearance.

North Bowen Basin region: Other resource potential data guide

Publicly available geological data in the north Bowen Basin region are compiled to produce statements of existing knowledge for natural hydrogen, hydrogen storage, coal and mineral occurrences. This data guide also contains assessment of the potential for carbon dioxide (CO2) geological storage and minerals in the basin region.
Geochemical analyses of gas samples from petroleum, coal and coal seam gas boreholes in the basin show traces of natural hydrogen. However, the generation mechanism of the observed natural hydrogen concentration is unknown.
Numerous mineral occurrences are found in the basin. Most contain gold, which historically has often been mined. Most occurrences are small, with some exceptions, such as Cracow, Golden Plateau, Kauffman’s Prospect and Miclere gold deposits. The north Bowen Basin has potential for epithermal gold-silver and gold-copper deposits in the deeper formations, but the depth of much of the basin makes exploration and mining difficult and expensive. There is also potential for sandstone-hosted uranium and paleoplacer gold deposits in the upper coal-bearing formations, such as what is seen in the Miclere area.
The north Bowen Basin has a significant quantity of coal, with 152 deposits found in the basin, totalling about 47 billion tonnes of black coal. The results of CO2 geological storage assessment of 3 play intervals in the north Bowen Basin suggest there is low storage potential within the basin.

Geology of the Stillwell Hills GIS dataset

The Stillwell Hills region comprises granulite-facies gneisses which record evidence for multiple episodes of deformation and metamorphism spanning more than 2500 million years. The predominant orthogneiss package (Stillwell Orthogneiss) is thought to represent the margin of an Archaean craton exposed in Enderby Land, some 150 km to the west that was reworked during the late Proterozoic. Younger additions to the crust include Palaeoproterozoic charnockitic gneiss (Scoresby Charnockite) and Meso-Neoproterozoic mafic sills and dykes (Point Noble Gneiss, Kemp Dykes) and felsic pegmatites (Cosgrove Pegmatites). Subordinate supracrustal rocks, including metaquartzite, metapelitic, metapsammitic and calc-silicate gneiss (Dovers Paragneiss, Sperring Paragneiss, Stefansson Paragneiss, Keel Paragneiss, Ives Paragneiss) are intercalated and infolded with the Archaean-Palaeoproterozoic orthogneisses.
This Dataset is derived from the map product 'The Geology of the Stillwell Hills, Antarctica' (GEOCAT 72717).

The Karumba Basin, northeastern Australia and southern New Guinea

The Karumba Basin in its present form coincides areally with the Gulf of Carpentaria and the river systems draining into it. The Basin is mainly of Cainozoic age, epi-cratonic, and superimposed on the Mesozoic Carpentaria Basin of the Trans-Australian Platform Cover. The development of the Karumba Basin related to the separation of Australia from Antarctica, and to subsequent plate margin events in New Guinea, in contrast to the evolution of the Carpentaria Basin which probably correlated with plate convergence to the east. The structural basin contains four main sets of deposits, each primarily resulting from an uplift episode. The oldest set, the Bulimba Formation, is probably of late Cretaceous-Paleocene age; the next, the Wyaaba Beds and equivalents, is Miocene to early Pliocene; the third, the Yam Creek Beds and equivalents, is of Pliocene age; the youngest began accumulating in the late Pliocene and is still being deposited. The total thickness of the four sets is about 400 m; they occupy a relatively small part of the present Karumba structural Basin.

NETGOLD - Lisle, NE Tasmania 1983 (P780), 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 NETGOLD - Lisle, NE Tasmania 1983 survey were acquired in 1983 by the TAS Government, and consisted of 1073 line-kilometres of data at 200m line spacing and 70m 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.
