GEOS314: Magmas, Fluids and Ore Deposits |
Day Students: 3 day field excursion, dates TBA
An understanding of the behaviour and evolution of silicate magmas and aqueous fluids in both the crust and mantle is developed. Examples of mafic/ultramafic and intermediate-silicic magmatic rock associations and their linked fluids and ore deposits are treated in terms of their geochemical behaviour and petrology. This treatment ranges from a deposit scale to a mantle-domain scale. Physical attributes of magma-fluid systems and isotopes are considered as petrogenetic and exploration tools. Important ore deposits related to fluid flow in sedimentary basins are also outlined. Practical work involves evaluating geochemical databases and microscopic examination of important suites. Field work will be conducted in an area containing an igneous complex and associated ore deposits.
