Abstract
Geological, geochemical, and geophysical studies in the Comstock Lode district and adjoining parts of the Virginia Range near Virginia City, Nev., have resulted in recognition of two geophysical anomalies and several geochemical anomalies in an area north of Virginia City. The geophysical anomalies were found during an induced-polarization survey carried out to aid in tracing the Comstock fault, the principal structure localizing the bonanza silver-gold deposits of the Comstock Lode district, in an area of intensely altered rock and alluvial cover about 5 miles north of Virginia City. Geochemical anomalies showing mercury in excess of 5 ppm (parts per million) were found in altered rocks along the Cornstock fault near Cornwall Knob about 5 miles north of Virginia City and in the Washington Hill area, 6 miles farther north.
