An Experimental Investigation Of Gold Incorporated Into Bornite, Intermediate Solid Solution (Iss), And Pyrrhotite: Implications For Porphyry Ore Deposits, Carli Lynn Schmidt

Graduate Research Theses & Dissertations

Magmatic-hydrothermal ore deposits contain metals sourced from a melt and transported to shallower levels by a magmatic volatile phase (MVP) where they can be deposited as native elements or structurally bound in sulfide or oxide minerals. Porphyry ore deposits are a major subclass of such and contain plentiful concentrations of societally significant metals including copper and gold. These deposits include the Grasberg porphyry Cu-Au-(Mo) deposit in Indonesia, the Bingham Canyon porphyry Cu-Mo-Au deposit in Utah, USA, and the Far Southeast porphyry Cu-Au deposit in the Philippines. In these systems gold is often found associated with bornite, intermediate solid solution (ISS, …
