By means of microscope and electron microprohe analyzer（EMPA），the types of minerals were identified in Jinlongshan gold deposit，which are pyrite，arsenopyrite，tennantite，zinc tetrahedrite，boulangerite，galena，sphalerite，gersdouffite，realgar，etc.Among them，it is the firstly discovered in this area that the mineral species of tennantite，zinc tetrahedrite，boulangerite，gersdouffite and so on.And it was also ensued that the pyrite with arsenopyrite proliferative endless belt and the banded pyrite with arsenopyrite accretionary body by the electron microprohe observation and test，all of them form the banded and taxitic pyrite.The content of metal sulfide is low and sparsely distribution with disseminations in Jinlongshan gold deposit，so researching the mineral distribution features are very difficult.Through the field observation，we found that the distribution and structure of sulfide is proportional to the deformation intensity of tectonic deformation.In other words，the stronger tectonic deformation means the higher sulfur content，the coarser grain and the more intensive distribution.The results show that the sulfide is mainly rendered banded distribution in strong deformation zone，and the sulfide is mainly rendered sparsely disseminations distribution in weakly deformation zone.Through the field observations and the laboratory study，the interrelations of sulfide have been ensured，which is formed through a three stage，the early stage is the slow crystallization stage，the middle stage is the rapid crystallization stage，and the later stage is overlay formation stage.
