The middle and lower Yangtze valley is one of the most important metallogenic regions in Eastern China, where more than 200 polymetallic Cu-Fe-Au, Mo, Zn, Pb, Ag deposit occur. The Shaxi porphyry Cu-Au deposit is located in the central Anhui Province, and is related to Jurassic-Cretaceous intrusions. Measured sulfur isotope compositions of sulfides are consistent with a mantle sulfur source, and there is little evidence for sedimentary sulfur input. Hydrogen and oxygen isotopic compositions shows that the ore-forming fluids were of magmatic derivation, whereas post-mineralization fluids had a component of meteoric water.
