Abstract

Results are given of two geophysical surveys carried out by the Bureau of Mineral Resources for the proposed Great Lake Power Development on behalf of the Hydro-Electric Commission of Tasmania. In the 1957-58 survey seismic reflection, seismic refraction, resistivity, gravity, and magnetic methods were used. Although no reflections were recorded from the bottom of the dolerite sill, the magnetic and seismic surveys provide supporting evidence for features indicated by the interpretation of a gravity survey in 1951. In the 1959 survey a new tunnel line was investigated with seismic refraction, gravity, magnetic, and resistivity methods. Estimates are made of the thickness of scree material, glacial deposits or weathered layers. Some shear zones were located and information was obtained on the nearly vertical subsurface boundary between sediments and dolerite.
