| Abstract: | Studies on REE and sulfur isotope geochemistry of the Huashugou(iron)copper deposit indicate that this Deposit formed in a submarine rift environment near continental margin. The ore-forming material mainly come from The Proterozoic basic volcanic rocks, sulfur from the sea water. The formation process of the deposit includes: water Rock interaction ,eshalation-sedimentation, and later, metamorphism etc. So the Huashugou deposit is an eshalationsedimentation-metamorphic(iron)copper deposit. |
