The potassium silicate (K-silicate) alteration zone is the main ore contributor in porphyry copper deposits worldwide. Knowledge of element behaviors and mineralization processes essential for an improved understanding mineralization, but they are still not well understood. In this study, we reacted synthetic Cl-rich fluids, containing K, Na, Cu, Mo, Zn, etc., with andesite a complex experiment...

Porphyry deposits are the dominant sources of copper and major several base precious metals. They commonly formed via repeated emplacement hydrous magmas associated fluid exsolution. As a result, mineralized hydrothermal veins may undergo multiple deposition reopening processes that not fully accounted for by existing models. The Tongchang porphyry Cu deposit is rare example being related to si...
