How Much Water in Basaltic Melts Parental to Porphyry Copper Deposits?
Frontiers in Earth Science, 2020 Porphyry copper deposits are formed by aqueous fluids exsolved by differentiated, mantle-derived magmas variably mixed with crustal melts. Water is essential to form porphyry Cu mineralization, and this explains why these deposits are found only at ...

Oceanic anoxic events, subduction style and molybdenum mineralization
Solid Earth Sciences, 2016 Nearly half of the world's Mo resources are hosted in Cenozoic porphyries along the east Pacific margin. In contrast, there are essentially no large Mo porphyry deposits along the west Pacific.
