| Abstract: | Anomalous geochemical and geophysical properties correlate spatially with epithermal Ag-Au deposits in altered volcanic rocks. Areas of low 18O, low magnetic susceptibilities, low remanent magnetizations and relatively high rock densities are much larger than the zones of obvious (not shown) hydrothermal alteration. Low aeromagnetic intensities and positive Bouguer anomalies are also associated with the altered rock, as which has delta 18O <6per mille. The altering and mineralizing fluids were Tertiary meteoric waters.-G.J.N. |
