Petrophysical results from rocks of the wyalong district and their significance in local magnetic interpretation

Abstract

A prominent 1,000 nT aeromagnetic anomaly occurs in the south-western corner of the Forbes 1:250,000 sheet near the towns of Wyalong/West Wyalong. The anomaly lies on the western edge of an extensive meridional regional aeromagnetic feature about 50 kilometres wide, more than 300 kilometres long and several hundred nanoteslas in amplitude. On the regional BMR aeromagnetic map the Wyalong feature appears as a complex cluster of highs forming the northern termination of a linear anomaly extending well into the Cootamundra sheet to the south.
