通过显微镜和电子探针鉴定金龙山金矿的矿物种类主要有黄铁矿、砷黄铁矿、毒砂、砷黝铜矿、锌黝铜矿、硫锑铅矿、方铅矿、闪锌矿、辉砷镍矿和雄黄等，其中，砷黝铜矿、锌黝铜矿、硫锑铅矿和辉砷镍矿等为首次在该区发现的矿物种类。通过电子探针观察与测试，确定黄铁矿具有含砷黄铁矿增生环带，而且条带状黄铁矿具有含砷黄铁矿增生体，形成条带状和斑杂状黄铁矿。金龙山金矿中金属硫化物含量偏低，多呈稀疏浸染状分布，研究矿物分布特征非常困难。通过野外观察发现，硫化物的分布与构造变形的强弱成正比，构造变形越强则硫化物的含量越高，颗粒越粗大，分布越密集。研究得出强变形带中硫化物多呈条带状分布，弱变形域中硫化物多呈稀疏浸染状分布。经过野外观察与室内研究确定了硫化物的相互关系，其形成经历了3个阶段，早期阶段为缓慢结晶阶段，中期阶段为快速结晶阶段，晚期阶段为叠加形成阶段。

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.
