Geological Characteristics and Prospecting Direction of Nacheng Silver Gold Polymetallic Ore in Guangdong Province

Nacheng silver-gold polymetallic ore mine found in Yunkai area,Guangdong,is a medium scale mine.It is located in the core of Yunkai uplift and the centre of Wuchuan-Sihui fault,in the western section of South China fold system.It has good ore-forming geological conditions around the mining area,along with faults developing and strong magma action.A lot of veins with characteristic of ore output in groups,which is mainly controlled by the lower-level tensorshear faulting,as a result,its space arrangement showing the pattern of intensively left addressed.In recent years,through the large research work,outlining 10 mine areas for the gold silver polymetallic ore,all of which present an increase trend of silver gold polymetallic ore enrichment,showing a good prospect for finding mineral resources.Through the study of ore deposition,quality,texture and structure,chemical composition and metallogenic stages of mineral formation sequence,we discussed the deposit genesis,summarized the prospecting marks,and provided detailed geological data for further prospecting and mining scale expanding in deep and edge.
