玉龙斑岩铜矿带是西藏最大的斑岩铜矿带之一。该区域研究程度较低，遥感地质信息的提取对找矿预测意义重大。作者利用TM数据和OLI数据，通过波段组合、主成分分析、最小噪声分离技术提取了玉龙地区与斑岩铜矿有关的地质信息。运用GIS技术制作了区域内的地球化学异常图。在地质、遥感、地球化学异常综合分析的基础上，圈定了找矿远景区，提出了藏东高植被覆盖区找矿技术方法的组合。

The Yulong porphyry copper deposit belt is one of the largest deposit belts in Tibet, China. Because of the poor research, the extraction of remote sensing geological information is important for metallogenic prediction. Based on the process of color composites、 principal component analysis、 minimum noise fraction by making use of TM data and OLI data, a lot of infor-mation relating to the porphyry copper deposit is extracted. To get the regional geochemical anomaly map by using the technolo-gy of geographic information system. Based on the comprehen-sive analysis of geology, remote sensing and geochemical pros-pecting, they determine prospective areas for seeking ore depos-its, present prospecting method for porphyry copper deposit in the dense vegetation area.
