Abstract

The Australian Geodynamics Cooperative Research Centre (AGCRC), through the Australian Geological Survey Organisation (AGSO, now 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

On behalf of the AGCRC, AGSO acquired 105 km of seismic reflection data in the Cabonne region of central New South Wales in the spring of 1997. The data form a sub-set of information in the "Eastern Lachlan Project" an Australian Geodynamics Cooperative Research Centre initiative. Gravity readings and drill cutting analysis (by CRCLEME) were also acquired to assist in geological interpretation. The AGCRC had previously (July, 1997) acquired wide angle seismic data along a north-south transect over the Molong-Wyangala Structural Zone (Leven, et. al, 1998) The 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.
