GSWA Kurnalpi North Thorium 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 thorium grid has a cell size of 0.00021 degrees (approximately 22m) and shows thorium element concentration of the Kurnalpi North, WA, 2013 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2013 by the WA Government, and consisted of 92672 line-kilometres of data at 100m line spacing and 50m terrain clearance.

3-D seismic reflector orientations from 2-D lines across the Kalgoorlie Goldfields

Conference abstract on seismic reflector orientation analysis from the Yilgarn Craton (Western Australia):
Interpretation of seismic data in hard rock areas is challenging due to lack of direct geological constraints from drilling and the more limited data available typically available from sparse 2-D profiles in comparison to hydrocarbon exploration surveys. Estimates of the 3D orientation of reflectors can help associate specific reflections, or regions of the crust, with geological structures mapped at the surface whose orientation and tectonic history are known. Here we present a method analogous to semblance velocity analysis that utilizes varying source-receiver azimuths to derive continuous estimates of 3-D reflector orientations along onshore 2-D reflection profiles. For each zero-offset time within a common depth point supergather, the semblance is calculated along 3-D travel time curves, and the dip and strike of the most coherent reflection is determined. Relative errors in these angles are derived from the range of travel time curves that have semblance values greater than a specified fraction, for example 90%, of the maximum. The potential of the method is illustrated using a section from line 10GA-YU1 from the Youanmi Terrane of the Yilgarn Craton in Australia in which the original field data have been replaced with synthetic in-line and cross-line reflections. Reflector orientations are generally well recovered where the range of available source-receiver azimuths is greater than 20o, but the method fails at lower ranges where the seismic line is almost linear, a behavior that is also observed in analysis of field data. When this approach is applied to data from the 2019 seismic survey around Kalgoorlie in the Eastern Goldfields, the orientations of both moderately dipping volcanic stratigraphy and faults are recovered. Integration of these local orientation attributes into an interpretation of migrated seismic data requires that the orientations also be migrated. We use a simple approach to the 2-D migration of these attributes that utilises the apparent dip of reflections on the unmigrated stack, and maps reflector strike, for example, to a short linear segment depending on its original position and a migration velocity. Deployment of off-line receivers during future seismic acquisition will allow the recording of a larger range of source-receiver azimuths that can produce more reliable estimates of these reflector attributes than is possible with the limited range of azimuths available from standard 2-D crooked-line acquisition.

Deformation of the crust and mantle in central Australia

Three zones of retrograded crystalline basement rocks have been delineated in central Australia. One, along the southwestern margin of the Amadeus Basin, was deformed about 600 m.y. ago during the Petermann Ranges Orogeny. Two one north of the Amadeus Basin, the other north of the Ngalia Basin were deformed during the Carboniferous Alice Springs Orogeny. Each retrograded zone is highly deformed and is flanked on one side by folded and thrust sedimentary rocks and on the other by granulite and amphibolite facies rocks. The high-grade rocks appear to have resulted from several metamorphic episodes in the Precambrian. A major gravity gradient is associated with each retrograded zone; the Bouguer anomaly highs generally occur over the areas of high-grade metamorphic rocks, and the lows over the sedimentary basins and retrograded rocks. In general, the deformed and retrograded zones are moderately to gently dipping. The gravity gradients are so wide and steep that to explain them the deformed zones must pass through the crust into the mantle beneath. The crust and mantle above each deformed zone have been upthrust, bringing granulite facies rocks to the surface and producing Bouguer gravity anomaly highs over the uplifted lower crust and mantle. The deformed zones are similar to the subduction zones that may develop on the margins of continents, but there is no evidence of continental collision in central Australia when they were formed, and they are regarded rather as possible examples of intracontinental plate reactions. They may have extended right across the continent or may terminate against strike-slip (transform) faults. A possible site for such a transform fault in Western Australia is discussed, but its existence is speculative.
