Shop state copper polymetallic deposit is located molybdenum porphyry copper belt in the eastern section , is typical of a large porphyry copper deposit of molybdenum . Molybdenum Copper lanes equiaxed , irregular shape , form the basic agreement with the porphyry body , mainly occur in two feldspar granite porphyry body and the outer contact zone of hornfels zone ; lead-zinc mine in southern main body bedded , cystic hosted in Naropa pile group (P1l) F1 fault fracture zone , limestone , marble lens edge contact zone . Ore structures are disseminated structure , veinlets structure, lumpy structure, brecciated structure , etc. ; structure mainly euhedral granular texture , subhedral granular texture , anhedral granular structure , including the structure of edge structure , account of residual structure. Ore minerals are pyrite , molybdenite , chalcopyrite , galena , with minor sphalerite , bornite , magnetite, ilmenite and chalcocite and so on. Shop state mining process is divided into three metallogenic period, that the late magmatic , hydrothermal and supergene mineralization period period . Which is the state of hydrothermal mineralization Shop molybdenum-copper polymetallic ore deposits in the most important period is divided into three stages, namely Mo-Cu sulfide phases , Pb-Zn sulphide phases and Gyp-Cal phase. Mine alteration zonation annular distribution of potassium from inside to outside silicification - sericite zone (Si-Se), sericite zone (Se), sericite - clay of the band (Se-Ka), Green alteration zone plate (P). Molybdenum ore bodies mainly occur in the Si-Se ( K silicification - sericite zone ) and Se-Ka ( sericite - clay based band ) in ; molybdenum -rich region forms as veins , deep enrichment significantly better in the shallow part . Copper orebodies mainly occur in the Se-Ka ( sericite - clay based band ) and P ( blue plate alteration zone ) in ; copper enrichment zone forms as veins , deep enrichment also significantly better than the shallow .
