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 - sub-surface geology at a regional and mine scale - provide more information on regional crustal thickness and major features - stratigraphic and structural architecture of the mineral system - 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 Bolder-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. {"type": "Polygon", "coordinates": [[[121.0, -31.0], [122.0, -31.0], [122.0, -30.0], [121.0, -30.0], [121.0, -31.0]]]} 121.0 122.0 -31.0 -30.0 AU-WA Earth Sciences GA Publication Published_External Record mineral deposits seismic sections structural geology Download the Record (pdf) documentDigital Download the Record (pdf) PDF Unnamed resource documentDigital HTML
