| Abstract: | Epithermal Au (Cu Ag) deposits occur largely in volcano plutonic arcs associa ted with volcanism and subvolcanism, with ages similar to volcanic activity. Two en d member styles of epithermal Au (Cu Ag) deposits, high sulfidation and low s ulf idation, have been identified. Based on research, these two deposit styles are f ormed from fluid system of distinctly different chemical composition in contrast ing volcanic environment. Mineralizing age of Epithermal Au (Cu Ag) deposits i n east China are relatively old than other countries, and mainly berccia pipe typ e and porphyry type. |
