湖南道县小蓬江铅锌银矿床地质特征及找矿远景评价

Geological characteristics and prospecting potential evaluation of the Xiaopengjiang lead zinc-silver-deposit in Daoxian County,Hunan

湖南省道县小蓬江铅锌银矿床属高—中温岩浆热液充填交代型铅锌多金属矿床,分布于金鸡岭岩体西部内接触带中,受区域性断裂F1、F2的次级断裂带控制。岩体内接触带、控矿断裂及次级断裂带、云英岩化等蚀变、民采老窿等为矿床的找矿标志。矿区内北东向矿脉具沿走向、倾向延伸较稳定的特点,其深部具有扩大远景的可能。

The Xiaopengjiang lead-zinc-silver deposit in Daoxian county, Hunan province,is a high - middle temperature magmatic hydrothermal filling metasomatic lead-zinc polymetallic deposit. The ore veins are distributed in the contact zone of the western of the Jinjiling rock body, and are controlled by the secondary fault zone of the regional fault F1 and F2. The contact zone, ore controlling fault and secondary fault zone, alteration of greisenization , and the Mining old holeare the prospecting criteria for the deposit. The NE trending vein in the mining area has the characteristics of extending along the strike and tendencies, and its deep part has the possibility of expanding the prospect.
