Abstract

A consortium consisting of the Bureau of Mineral Resources, Geology &Geophysics (BMR) (now called the Australian Geological Survey Organisation (AGS0)),Department of Primary Industries & Energy, Australian Government; the Department ofMineral Resources (DMR) (formerly the Department of Minerals and Energy), NSW StateGovernment; CRA Exploration Pty. Ltd.; Geopeko Pty. Ltd.; Pasminco Pty. Ltd.;conducted the Cobar Basin Seismic Survey during October to December 1989. The main objectives of the Cobar Basin seismic survey were to acquire deep reflection seismic data along several seismic lines across the Cobar Basin and thebounding west and east margins, and acquire high resolution seismic data across zones of known mineralisation in the Cobar Basin and bounding margins. The BMR Sercel SN368seismic data acquisition system was used to record the deep reflection seismic data, and the DMR Sercel 338 seismic data acquisition system was used to record the high resolution seismic data. The acquisition of the seismic data would be used to test newtectonic models recently developed for the evolution of the region, and for genesis and control of mineralisation, especially in rock units of the Cobar Basin around Cobar. On aregional scale the acquisition of seismic data would be used to test models of basin formation in the Cobar region which perhaps could be applied elsewhere in the LachlanFold Belt. The seismic reflection survey by the BMR, recorded 184 km of 8-fold CMP deepreflection seismic data to 20 seconds two-way travel time, along three seismic lines. The lines were positioned to investigate major structures defined by surface geology andpostulated in the recently proposed tectonic models. To provide seismic reflection data of the near surface geological rock units, 2.85 km of high resolution seismic data wererecorded along Line 2 by DMR, across a geological setting associated with mineralisation structures.
