| The Ba Jiazi molybdenum mine located in JianChang county is studied for object in the paper. Some geological disciplines theory and methodologies like petrology, mineralogy, economic geology, mineral exploration, geochemical etl are used for analysis of the regional geological setting, geological profile, and interpretation of the data of induced polarization geophysical anomaly method. The geological features of mineralization are described and the magmatic, tectonic, ore-controlling factors such as wall-rock alteration are analyzed combined with construction materials on-site drilling. The results are as follows:the shape and location of mineralization are closely related to magmatic rocks, fractures and produced in the vicinity of fracture intercourse. The ore-bearing hydrothermal fluid produced from the Yanshan granite porphyry Jurassic period is determined through the analysis of rock samples in the mining. When the ore-bearing hydrothermal fluid with the pulse-type granite porphyry invasive, the fractures of the rock existed in the internal of porphyry and the activities of the early structural damage provide a good space for ore. The type of wall rock alteration and horizontal banding are summed up according to the structure and structural characteristics of the ore. Finally, the mineral in the study area is predicted using of weight of evidence method with GIS platform. |
