Discussion on geological characteristics and genesis of Daqinglonggou silver polymetallic deposit of Henan province

Daqinglonggou silver polymetallic deposit occurs in the stratum of mesoproterozoic Pzler and belongs to the marine volcanic sedimentary rock series within the taphrogenic trough on the southern margin of the north China platform,where the deposit is controlled by tectonic fracture and alteration belt.According to the study of the deposit geological characteristics,the resource of metallogenic material and the metallogenic regularities etc.,the deposit of Daqinglonggou is considered to be an infiltration hydrothermal type sliver-gold polymetallic deposit which is controlled by the tectonic fracture and alteration belt and is related to Yanshanian magmatism.
