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.
