Yalgoo-Badja, WA, 2004 (P1060), radiometric line data, AWAGS levelled

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 Yalgoo-Badja, WA, 2004 (P1060), radiometric line data, AWAGS levelled were acquired in 2004 by the WA Government, and consisted of 16021 line-kilometres of data at 400m line spacing and 60m 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.

Drainage modification associated with the northern Lapstone Structural Complex, New South Wales, Australia

The Lapstone Structural Complex (LSC) comprises a series of north-trending faults and monoclinal flexures forming the eastern margin of the Blue Mountains Plateau, ~50 km west of the Sydney CBD. The LSC is considered a potential source of large earthquakes, however its evolution, and in particular its tectonic history is not well constrained. 
The LSC is bounded to the west by the Kurrajong Fault System (KFS), a series of en echelon reverse faults downthrown to the west. Streams crossing the LSC oversteepen by about 2-5 times over these faults. This study aims, through longitudinal profile analysis of 18 streams crossing the LSC coupled with field observation, to determine whether the oversteepening can be attributed to a lithological change at the faults, or tectonically-induced disequilibrium. 
Two approaches are used. Firstly, plots of log slope versus log distance (DS plots) are produced for each of the streams. As a result of noise in the topographic data, these results are inconclusive in demonstrating either situation. Secondly, an area-slope relationship, defined by A0.4S (where A = area and S = slope), is plotted against downstream distance. This factor is derived from the stream incision law, dz/dt = KAmSn, where K is assumed to be constant, and m and n are positive constants relating to erosional processes, and basin hydrologic and geometric factors. The analysis shows that in all but two streams, values for A0.4S are at a maximum over the LSC. Peak A0.4S values of about 0.2 are estimated to be equivalent to vertical incision rates of about 70 m/Ma. A0.4S varies with lithology; however the lithological effect is demonstrated to be of similar magnitude or smaller than the apparent structural control exerted by the LSC.
All streams with catchment areas less than 100 km2 have developed swamps upstream of faults on the LSC. Sediment accumulated in these swamps is generally 0.5-4 m thick, but reaches 14 m in Burralow Swamp. In Blue Gum Creek and Burralow Swamps, the sedimentary sequence includes an organic clay layer indicative of low-energy depositional conditions. Previous radiocarbon dating and pollen analysis suggests the sediment is of Pleistocene age. The elevation of the clay layer is similar to that of bedrock downstream of the faults, consistent with damming related to from tectonically induced uplift.

Moho variations in northern Australia

Constraints on the morphology of the Moho are essential to establish reliable models of the subsurface and infer the evolution of the Australian crust. Reliable information on crustal thickness variations is important for thermal modelling and structural mapping, for both energy and mineral system studies. Here, we combine information from both passive seismic deployments and full-crustal reflection seismic profiling to produce a new representation of the character of the Moho in northern Australia. Data coverage has been dramatically improved by investments, under the Exploring for the Future program, in new deployments of passive seismic instrumentation and expansion of the network of reflection seismic profiles in the South Nicholson and Barkly regions. Using a new approach to combining results from different classes of seismic analysis, different spatial sampling associated with the various types of data have been taken into account. The resulting Moho surface reveals small-scale features not seen in previous models. New data reveal that some Moho discontinuities are clearly associated with known structures such as the Willowra Suture. Similar ~100 km wavelength undulations are visible in areas under cover that may indicate the presence of unknown major structures. Significant base metal mineral deposits appear to be localised along the edges of thicker crustal block.

Harris Greenstone Domain GeoPDF

The Harris Greenstone Domain (HGD) is a late Archean-Proterozoic arcuate tectnostratigraphic terrane in the centre of the Gawler Craton. It is bound to the south by the Yerda Shear Zone and has a lithological zone boundary to the north with the Wilgena Domain. The basement comprises Archean ultramafic-mafic extrusives (Lake Harris Komatiite), aluminous metasediments (Christie Gneiss), felsic extrusives and intrusives (Kenalla Gneiss), felsic intrusives (Glenroth Granite), and Proterozoic felsic intrusives (Hiltaba Suite Granite, St Peter Suite), felsic and mafic extrusives (Gawler Range Volcanics), and fluvial-marine sedimentary rocks (Tarcoola Formation, Pandurra Formation).
The HGD is characterised by a series of sub-parallel east-northeast trending sinuous magnetic high features flanked by large ovoid to elongate magnetic highs and lows. The prominent narrow magnetic highs constitute the Archean Harris Greenstone Belt (HGB). Rock types in this poorly exposed belt include komatiite, komatiitic basalt, tholeiitic basalt, and subordinate banded iron formation, metasediments, felsic volcanics, and pyroclastics metamorphosed to amphibolite facies during the Sleafordian Orogeny at ~2440 Ma. The Lake Harris Komatiite, which represents the most eastern occurrence of komatiite in Australia, has potential for Ni-Cu-PGE sulphide and lode-Au mineralising systems. The prospective greenstone sequence is covered by thin (&lt;50 m) Quaternary sand and Eocene fluvial channel deposits. The distribution and structure of the greenstones is based largely on interpretation of aeromagnetics, gravity, and diamond drillcore.
This map has been produced as a GeoPDF, which is an extension to the standard PDF file format viewed using Adobe Acrobat Reader. Layers can be turned off and on to customise the view of the data, similar to using Geographic Information System tools. In addition, GeoPDF maps are georeferenced to be compatible with other coordinated geographic data. Coordinate locations and distances can be retrieved automatically.
