Structural geology of the Mount Polley Cu-Au district, south-central British Columbia

Creator:

Wafforn, Stephanie R.

Abstract:

The Mount Polley copper-gold deposit is one of a series of porphyry copper deposits that occur in a belt of accreted Mesozoic age island arc terranes in the Canadian Cordillera. The deposit comprises three breccia-hosted Cu-Au ore zones that are associated with a series of monzodiorite to monzonite intrusions emplaced...

Compositional variations in hydrothermal white mica and chlorite from wall-rock alteration at the Ann-Mason porphyry copper deposit, Nevada

Creator:

Cohen, Julia F.

Abstract:

The detection of subtle variations in mineral chemistry in zoned hydrothermal alteration associated with the formation of porphyry copper deposits by short-wave infrared spectroscopy and rock chemistry are potentially valuable vectoring tools for mineral exploration. In order to correctly interpret the data collected by these methods, results must be calibrated...
