Abstract
Ground magnetic, gravity, and electromagnetic measurements in the Oakfield Hills area have delineated a series of steeply dipping, dikelike rock units with high apparent susceptibility, high density, and often high conductivity. The measurements were made to investigate the source of a 3000-gamma aeromagnetic anomaly. The rock units are apparently a series of lenticular beds of manganese-bearing iron formation which have been thermally metamorphosed by a nearby intrusion. Some of the electromagnetic anomalies are probably caused by the presence of sulfides.
