摘　　要：柿竹园蛇形坪—横山岭铅锌矿床是一个含银高的矿床,系统研究了该矿床伴生银(金)的分布特征.并探讨银(金)矿化的富集机理,认为在该区及外围有利成矿的断裂破碎带地段.可能存在有独立银(金)矿体或与铅锌矿体在空间上重叠产出的特征.值得注意寻找独立金银矿体.The associated silver tenor is high (160g / t) in Shizhuyuan (Shexingping-Hengshanling) lead-zinc deposit in Hunan. The distribution regularity for the associated gold-silver was summarized, and their enrichment mechanism of the mineralization was approached preliminarily, and it is suggested that the gold-silver ore-body was possibly existed or was formed in some areas of the faulted-broken zones that was advantageous to Pb-Zn mineralizations and may be superimposed by Ag (Au) mineralization. This suggestion was put forward to look for the single gold-silver ore-body in this district and its periphery.
