The use of sulfide mineral chemistry to understand PGE mineralization processes in the Northern Limb of the Bushveld Igneous Complex
… primarily because it contains significant PGE-Ni-Cu mineralization and there is no consensus regarding the mineralization processes, particularly on the role of footwall assimilation. One puzzling aspect is the apparent lack of correlation between sulfide abundance and PGE-Ni-Cu contents. Another …

Geochemical Constraints of Porphyry Cu Deposits-Forming Magmas in Sonora, Mexico
Porphyry Cu deposits (PCDs) represent the most significant source of economic-grade copper (Cu) on Earth (Sillitoe, 2010). PCD formation is intimately linked to the magmatic and tectonic evolution of convergent margins (Sillitoe, 2010). While the metallogenic characteristics of PCDs have been …

The Marcona - Mina Justa District, South-Central Perú: Implications for the Genesis and Definition of the Iron Oxide-Copper (-Gold) Ore Deposit Clan
… in the Central Andes. Hydrothermal activity occurred episodically from 177 to 95 Ma and was controlled by NE-striking faults. At Marcona, emplacement of massive magnetite orebodies with subordinate, overprinted magnetite-sulphide assemblages coincided with a 156-162 Ma episode of eruption of …

The stratigraphic and structural controls on copper-gold mineralization at Cassenha hill prospect, within the Archean to Paleoproterozoic Angolan shield, Congo craton, South Western Angola
… Cassenha Hill prospect is characterized by the occurrence of partially altered and highly oxidized metasedimentary rocks (meta-mudstone, meta-siltstone, carbonate-rich rock, meta-sandstone, breccia, and quartzite), and altered isolated granitoids. This study represents the first detailed study of …
