Brief description

Geoscience Australia through its partnership in the Australian Geodynamics Cooperative Research Centre (AGCRC) and Kalgoorlie Consolidated Gold Mines (KCGM) completed a joint research project to image the crustal structure of the Kalgoorlie region to develop a knowledge of the shallow and deep structures, tectonics, and fluid migration pathways. The Australian National Seismic Imaging Resource (ANSIR) was contracted to acquire the seismic data. The project's objectives were to obtain a better understanding of 1. sub-surface geology at a regional and mine scale 2. regional crustal thickness and major features 3. stratigraphic and structural architecture of the mineral system 4. timing and locations of fluid migration pathways The seismic survey obtained 25 km of 10 fold CMP (common midpoint) regional reflection seismic data along two traverses and 8 km of 10 fold CMP high resolution reflection seismic data along another two traverses. The data are of good quality and similar to both the 1991 and 1999 Eastern Goldfields reflection seismic data to the north and south of the survey area. The major outcome of imaging the four localities included mapping the Golden Mile and Boulder-Lefroy Faults, and the Boorara Shear at depth. This new information indicates the Golden Mile Mine was fed by a suite of relatively minor faults dangling off the major crustal-scale Boorara Shear. The dangling element relates to percolation theory. The detachment surface was imaged on all seismic traverses. Thrust duplexes were interpreted above the detachment surface.

Statement: AGSO, AGCRC, and KCGM acquired 33 km of seismic reflection data in the Kalgoorlie region of Western Australia in September 1997. The data form part of the Australian Geodynamics Cooperative Research Centre's "Kalgoorlie Project". AGSO (formerly Bureau of Mineral Resources, BMR) previously acquired a regional east-west transect in 1991 to the north of Kalgoorlie, as part of the Eastern Goldfields Seismic Project (Drummond et ai., 1993 & Drummond et al., 1997). The transect imaged the Archaean greenstone belt, major structures and the detachment surface.
