Ore-Forming Processes

This course examines processes involved in the genesis of magmatic and hydrothermal ore deposits. Emphasis is placed on Ni-Cu-PGE and chromite deposits, the role of sulphur in silicate melts, and contamination and magma mixing. In considering hydrothermal deposits, topics include the types of hydrothermal fluids involved in mineralizing processes; sulphur and chloride species; and the solubility of metals, and alteration and hydrogen metasomatism including techniques to assess chemical gains and losses. Attention is given to porphyry copper, volcanogenic massive sulphides, epithermal and lode-Au deposits. Laboratories involve examination of selected sample suites, problem sets and a project. PREREQ: GEOL 3206/7 and GEOL 3607. (lec 3, lab 3) cr 3.
