摘要
论述银厂铅锌矿区地质背景和构造特征,阐明NW向张扭性断裂是铅锌矿体的控矿及赋矿构造。稀土元素特征显示成矿物质主要来自筇竹寺组和渔户村组,岩浆活动与铅锌成矿密切相关,成矿时代为海西期,成矿温度为148～220℃,属中低温热液矿床,为指导该区进一步寻找铅锌矿提供理论依据。
An overview of the geological setting and structural feature of Yinchang Lead-Zinc Deposit is disser- tated. The Northwest Tenso Fracture is the important ore controlling and hosting structure of Lead-Zinc orebody. The characteristics of lanthanon suggest that the metallogenetic material is mainly originated from Qiongzhusi and Yuhucun Formation. Magmatism is closely related with lead-zinc metallogenic. Metallogenic epoch of the deposits is during hercynian period and the mineral forming temperature is between 148 and 220~C, which indicates that the deposits belong to the mesothermal-epithermal ores. This paper provides a theoretical foundation for lead-zinc ore prospecting.
