Title: Study on the ore-controlling factors of Xiaoxinancha gold-copper deposit,Jilin Province
Abstract: Xiaoxinancha gold-copper deposit is located in the Eastern of Xing`an-Mongolian orogenic belt.The mineralization types can be divided into large quartz vein type and fine quartz veinlet type.The gold-copper ore veins were controlled by NNW direction compression-shearing faults.The ore veins are composed of the quartz-polymetallic sulfide vein of contain gold-copper and the veins veinlet-disseminated ore bodies in wall rocks.The main factors of controlling ore are faults in Xiaoxinancha gold-copper deposit,especially NW direction controlling distribution of ore bodies,the scale of ore bodies positively correlativity with fault size.There are a close relationship between diorite,diorite-porphyrite dike and metallogeny,being the immediacy wall rock of ore bodies.The ore bodies occurred in footwall and hangjngwall of diorite-porphyrite dike or in diorite-porphyrite dike,the magma activities provided a ore-forming materials of gold-copper ores.
