摘要
运用遥感 5要素 ,对区内含矿斑岩体、脆 -韧性剪切等强变形带、破碎蚀变带及其与围岩蚀变相关的色调异常信息进行了分析 ,认为该区金矿资源非常丰富 ,并提出了遥感金矿找矿远景区。
There has been a long history of exploiting gold mines in Sanjiang region of Tibet, and 40 gold mines have already been found. Nevertheless, these deposits are almost all associated mines, and only very few gold deposits are of independent type and their sizes are very small. The analysis of regional geological background and mineralization conditions shows that the area must have great gold potential. Using the five elements of remote sensing, the authors analyzed characteristics of satellite photographs of ore-bearing porphyry bodies, brittle-tough shear zones, shattered-altered envelopes and their tonal anomaly, thus delineating the perspective area of gold deposits.
