متن کاملThermal and Fluid Dynamics of Komatiitic Lavas Associated with Magmatic Fe- Ni-Cu-(PGE) Sulphide Deposits
The most important examples of magmatic ore deposits in volcanic rocks are Fe-Ni-Cu-(PGE) sulphides associated with Archean and Proterozoic komatiitic lava channels (Lesher, 1989). Komatiitehosted ores contain ~25% of the world’s nickel sulphide resource (≥ 0.8% Ni), including significant amounts of copper and platinum group elements (Ross and Travis, 1981). Field, experimental, and theoretical...

متن کاملMineralogy, Textures, and Relative Age Relationships of Massive Sulfide Ore in the West Shasta District, California
The Devonian massive sulfide orebodies of the West Shasta district in northern California are composed primarily of pyrite, with lesser amounts of other sulfide and gangue minerals. Examination of polished thin sections of more than 100 samples from the Mammoth, Shasta King, Early Bird, Balaklala, Keystone, and Iron Mountain mines suggests that mineralization may be divided into six paragenetic...
متن کاملA Review of the Behaviour of Platinum Group Elements within Natural Magmatic Sulfide Ore Systems
School of Earth and Ocean Sciences, Cardiff University, Main Building, Park Place, Cardiff CF10 3YE, UK The largest and most significant type of geological deposit of platinum group elements (PGEs) is that associated with magmatic base metal sulfide minerals in layered mafic or ultramafic igneous intrusions.The common association of PGEs with sulfide minerals is a result of processes of magmati...
