摘要
青海省什多龙地区位于都兰—鄂拉山基底隆起区的西北段,多期构造—岩浆活动叠加强烈,成矿地质条件优越,具有较大的找矿前景。本文利用ETM多光谱遥感数据,在区域成矿地质背景和岩矿光谱特征分析的基础上,通过遥感地质解译分析及矿化蚀变信息提取,优选出了4处成矿远景区,为该区进一步开展地质找矿工作提供了科学依据。
Shiduolong area of Qinghai province is located in the northwestern Dulan-Elashan basement uplift, which has strong superimposition of multi-phase tectonic and magmatic activities, superior metallogenic geological conditions, and great prospecting potential. On the base of regional metallogenic geological back- ground and rock-mineral spectra, by using ETM multi-spectral remote sensing data, the study has optimally selected four metallogenic prospect areas after interpreting and analyzing remote sensing geology and extract- ing mineralized alteration information, which provides scientific references for further geological prospecting within this area.
