Lode gold deposits are widespread in Precambrian lowmetamorphic clastic rocks in the Xuefeng Range, western Hunan, South China (Li, 1991; Luo et al., 1996). Among them, most deposits are typified by quartz-dominant vein systems with less carbonate and sulfide minerals (less than 5%), similar to most orogenic gold deposits worldwide. However, auriferous albite-quartz veins are widely distributed in the Liulincha region, western Hunan, there albite usually accounts for about 20-40% of ore veins. Up to now, more than 20 gold deposits/occurrences have been discovered in the Liulincha region, there almost all gold deposits occur in the Madiyi Formation, Neoproterozoic Banxi Group, and albite in ore veins is usually pink, therefore it has been mistaken as K-feldspar before 2006 (Wang et al., 2008). The Herenping deposit, as the largest gold deposit in the Liulincha region, was initially mined at the end of the Qing Dynasty. In spite of the long-term mining, this gold deposit is poorly constrained on its geological characteristics and its ore origin.
