摘　　要：驼路沟钴金矿床是近年来在青海省发现的容矿于奥陶—志留纪火山-沉积岩系中典型的火山喷气沉积-改造型矿床之一。通过对矿床成矿地质背景和地质特征的分析,以遥感技术为主要手段,从遥感的角度分别总结了ETM+图像中赋矿地层、控矿构造以及遥感矿化蚀变信息的特征,并依据遥感异常分布特征,认为驼路沟钴矿床的东西外延区和九七沟复背斜北翼部位找矿前景较好。The Tuolugou cobalt（gold） deposit is one of typical volcanic sedimentary-exhalative deposits occurring in Ordovician-Silurian volcanic-sedimentary rocks in Qinghai Province,discovered in recent years.Through the analysis for the geological background of ore formation and geological characteristics of deposit and adopted the remote sensing technique method,the author summarized characteristics of the source bed,ore-controlling structures and mineralization alterration information in the ETM＋ images,from the remote sensing angle and according to the distribution of remote sensing anomaly;and considered that the east and west extension areas in the Tuolugou cobalt（gold） deposit and the north wing of the Jiuqigou anticlinorium are better to prospect.
