摘　　要：通过对浙江省天台县银坑铅锌矿区开展1∶10000地质测量和1∶25000土壤地球化学测量工作,大致查明银坑出露的地层、岩性、构造、围岩蚀变等地质特征,在此基础上,进行土壤地球化学找矿研究,认为地化异常分布在中西部(铁丁湾)和北东部(沙坑),总体形态呈NW向展布,基本上反映了主要成矿元素的次生组合分布特征;综合分析表明,Cu、Pb、Zn、Ag、Au元素可作为本区直接的找矿标志。Through the works of geological survey at 1:10000 scale and pedogeochemical survey at 1:25000 scale in Yinkeng Pb-Zn-Ag mining area in Tiantai of Zhejiang,the outcropped strata,lithology,structure and wall rock alteration in Yinkeng are generally verified.On this basis,the pedogeochemical prospecting re-search indicates that geochemical anomalies are distributed in central-western part (Tiedingwan)and north-eastern part (Shakeng)along the NW strike in general,and the secondary combination and distribution fea-tures of main metallogenic elements are reflected basically.The comprehensive analysis suggests that Cu, Pb,Zn,Ag and Au may be used as direct clues for prospecting in this area.
