Highlights

The current reserves of the Chaihulanzi gold deposit can not meet the needs of continuous production of the gold mine，and further deep-edge prospecting should be carried out. Based on the theory of genetic mineralogy，the typomorphic characteristics of pyrite chemical composition in the the mining area were studied by mineral geochemistry method.The results are as follows：（1）The ratio of Co/Ni and the As-Co-Ni triangle diagram of pyrite show that the genesis of pyrite in Chaihulanzi gold deposit is complex，which is restricted by the strata of Jianping Group，regional metamorphism and magmatic hydrothermal activity；（2）The ratio of Au/Ag，S/Se and other characteristic values of pyrite show the characteristics of magmatic hydrothermal solution and the formation of ore-forming fluid is mainly related to the magmatic activity in this area；（3）Pyrite is rich in As，which indicates that gold in pyrite crystal exists as nano-particle gold，which indicates that ore-forming fluid has strong migration and the nano-particle gold has strong adsorption in rocks rich in carbon and clay.According to the composition characteristics of pyrite，combined with regional geology，mining area geology and the characteristics of the alteration zone，it is concluded that the Chaihulanzi gold deposit is mainly related to the intrusion of basic dikes. The basic vein not only brings some ore sources，but also the magmatic hydrothermal fluid brings gold in Jianping Group to further activate and enter into the ore-forming fluid. At the joint of NNE trending compression structural belt and NWW tensile fracture structural zone，the ore-forming fluid and surrounding rock are widely metasomated to form a gold deposit with altered rock type as the main part.There are good prospecting prospects in the deep metamorphic strata of Jianping Group in the southeast of the mining area，especially in the structural development part of the sericite graphite-bearing plagioclase gneisses.
