Geological characteristics and ore-forming regularities of Wangjiawan Gold Deposit in Liling,Hunan
Wangjiawan Gold Deposit is located in the southern part of the Jiangnan orogenic belt of the Yangtze continental block,on the southeast margin of the Li-Liu uplift belt,in the north segment of the Nanyuanchong com-plex fold,which is in the northeast Hunan sub-segment of the Hunan segment of the Qinhang metallogenic belt.It is situ-ated in the southern part of the Liuyang-Banshanpu exploration target area for gold,copper,lead,and zinc minerali-zation.The ore bodies mainly occur in the Lengjiaxi Group strata,with cleaved zones serving as ore-conducting and ore-controlling structures in the mining area,most of which are controlled by NW-trending cleaved zones.The ore types are predominantly primary ores,with an industrial type characterized by fractured altered rock with quartz veinlets.The hydrothermal mineralization of the deposit can be divided into 4 stages,with the quartz-pyrite-arsenopyrite-gold stage and the quartz-carbonate-polymetallic sulfide-silver gold stage being the main mineralization stages.Silicifi-cation,pyritization,and arsenopyritization are closely related to gold mineralization.Wangjiawan Gold Deposit is a mesothermal vein-type gold deposit dominated by metamorphic hydrothermal fluids.
