Brief description
The Australian Geodynamics Cooperative Research Centre (AGCRC), through Geoscience Australia conducted a seismic reflection survey in various localities in the eastern Lachlan Orogen of NSW, from October to November 1997. The objectives of the project were to obtain a better understanding of sub-surface geology at a regional and local scale and, in particular, provide more information on: 1. basement control on basin development 2. regional crustal thickness and major features within the basement 3. stratigraphic architecture of the basins 4. structural architecture of the basins 5. the location of fluid flow pathways The seismic survey acquired 105 km of 10 fold CMP (common midpoint) deep (20 second TWT) reflection seismic data along three traverses over a 6 week acquisition period. In addition to the seismic data, gravity observations were made at 300 m intervals along the lines. Drill cutting samples were also collected for analysis.

Lineage
Maintenance and Update Frequency: asNeededThe goals of the seismic reflection work are to improve the definition of the areas mineral potential and to understand
the geological controls on the distribution of these resources. In particular, an attempt was made to image WNW and N dipping structures that characterise the Lachlan Transverse Zone. The survey should also provide information on the
geometry of the Molong volcanic belt, the Siluro-Devonian Mumbil Shelf and Hill End Trough.
