Mineral Chemistries of the Tower Mountain Au Prospect, Ontario

Abstract

Hydrothermal fluid systems driven by magmatic activity are some of the most important ore forming processes for many metallic minerals. This project involves characterization of hydrothermal alteration associated with the Archean Tower Mountain Intrusive Complex and its related Au deposit. Mineral chemistry data has been collected from numerous primary and alteration minerals including feldspars, augite, hornblende, chlorite, titanite, magnetite and pyrite using a SEM/EDS detector. Initial results show two end-member fluid compositions are responsible for the alteration mineral assemblages.
