Abstract

The porphyry copper (gold) deposit at Shaxi is a special and large size deposit in eastern China. In the ore-forming process, the water and ore-forming materials in ore solution were magmatic in origin. Systematic studies of fluid inclusions reveal that the ore-forming system was characterized by relatively high temperature and low pressure as well as high contents of CO 2 and NaCl. Great amounts of evidence support that the fluid immiscibility played an important part in the formation of Shaxi porphyry copper (gold) deposits.
