The research of geological features of ore deposit ��fluid inclusion��sulfur and lead isotope has been recognized the ore-forming process consisting of five stages��including garnet-diopside��tremolite-actinolite�� magnetite��quartz-sulfide and quartz-calcite stages��which indicates the deposit as a typical skarn in type�� The testing results of homogenization temperatures and salinity of typical fluid inclusions from the selected three different mineralization stages show the homogenization temperatures value as 177�桫 600�� and salinity value as 7% �� 12. 2% in garnet-diopside stage; homogenization temperatures value of 147�桫 455�� and salinity value of 1%�� 5% in quartz-sulfide stage; and homogenization temperatures value of 130�桫 247�� and salinity value of 0. 5%�� 3% in quartz-calcite stage�� The gas composition of fluid inclusions were of CO2 ��H2O and a small amount of CH4 �� The δ34SV �� CDT of ore sulfide value was �� 2. 9 × 10 �� 3�� �� 0. 6 × 10 �� 3��and the composition was close to zero�� which the ore-forming meterals may come from mantle�� The 206Pb /204 Pb was 18. 099 �� 18. 508��207 Pb /204 Pb as 15. 532 �� 15. 578 and 208Pb /204Pb as 38. 071 �� 38. 176 in the ore sulfide��which refelceted the diversity metallogenetic material meterals��derived from a mantle-crust mix��
