Geophysical signatures over copper porphyries on the Pacific Rim

Abstract

Geophysical methods have played an important role in the discovery and definition of porphyry copper deposits in the Indonesian Archipelago. Geophysical methods of particular value are aeromagnetics, induced polarization, and to a lesser degree airborne radiometrics. Some deposits that have recently benefited from the application of geophysical methods, within the Indonesian Archipelago, include Bukit Hijau, Batu Hijau, and Beutong.
