The Taoyuan-Tianjing copper polymetallic deposit in Neiqiu county,Hebei Province is located on the west side of the arch fault bundle of the Taihang Mountains,and is an important prospective copper deposit area in the southern part of the Taihang Mountains.The main strata are metamorphic arkose sandstone and phyllitic slate in the second member of the Proterozoic Nansizhang Formation.The ductile and brittle shear deformation of the mining area is strong,and the surface mineralization and alteration are strong,which are manifested as strong limonization,silicification,chlorite and so on.The ore body mainly occurs in the chalcopyrite-pyritization-silicitization zone in the chlorite schist and its contact zone.The ore bodies are vein,mass and lenticular.Based on the characteristics of geological,geophysical anomaly and mineralization alteration in the mining area,the metallogenic conditions of the mining area are compared with regional metallogenic rules,the metallogenic geological conditions of the deposit are studied,the comprehensive prospecting information of geology,geophysics and geochemistry is summarized,and the metallogenic model of multi-stage and multi-source copper polymetallic deposit is constructed.Some suggestions are put forward for further prospecting in the development areas of peacock,limonized,silicified and chlorite in the study area.
