Geophysical signature of gold and porphyry copper mineral deposits in the Lachlan Fold Belt, NSW

Abstract

Regional geophysical data of the Lachlan Fold Belt can be interpreted to supplement geological knowledge, especially as large areas within the Fold Belt are without outcrop. The data are: (1) BMR aeromagnetic surveys (1960, 1961 and 1965) reprocessed by the Department of Mineral Resources (1983, 1984). (2) Enhanced images and filtered enhanced images of the aeromagnetic data. (3) BMR gravity surveys (11 km grid, 1959?67) and Department of Mineral Resources surveys (1984, 5.5 km grid, Forbes and Narromine sheets).
