摘要
After the origin mineralogy study of the main metallic mineral such as pyrite, pyrrhotine, chalcopyrite in the deposit, the authors point out that the ratios of Co/Ni, S/Se, Se/Te, Au/Ag in pyrite show magma hydrothermal origin features. The sulfur isotope constitutes of pyrite, pyrrhotine, chalcopyrite have deep-focus magma headstream feature, and happening disciplinary change as mine depth change. The microelement contents in pyrite, pyrrhotine, chalcopyrite have some different between north mountain ore block and south mountain ore block, it shows the zoning structure of the deposit. The temperature is middle-low temperature when the deposit emerged.
