研究区位于我国西北部青海与新疆交界的阿尔金山脉周边，地理环境恶劣，交通极为不便，以往地质工作程度较低，矿产调查工作实施困难。采用遥感技术，利用 SPOT-5、ETM 和 ASTER 多源遥感数据，通过对该区的地层及岩体、线性构造、环形构造等进行综合的遥感地质解译工作，同时提取铁染、羟基蚀变异常信息，从而初步确认研究区地质背景、构造应力状态以及矿化蚀变特征，为野外地质填图及矿产勘查工作提供较为详细的地质信息和找矿线索。

The study area is located in the Altyn Tagn Mountains which is adjacent to Qinghai and Xinjiang province. Because of the harsh natural environment,inconvenient traffic conditions,and little geology work which has been done before,it is hard to carry out mineral investigation.Based on remote sensing technology,taking the data of SPOT-5,ETM,and ASTER, the authors interpret some geological factors such as stratum,rock mass,linear structure,and annular structure,and also extract two kinds of remote sensing anomalies which are OH- and FA3 + .According to the information,the geological background, tectonic stress,mineralization-alteration features of this area has been initially established,which play an important part in field geological mapping and mineral exploration.
