摘要
喀湖错地区位于西藏第三条斑岩铜矿带——班公湖-怒江成矿带西段,该带资源潜力巨大,近年来相继发现了多龙和尕尔穷等具大型规模的铜多金属矿床。为进一步拓展其铜矿资源,利用ETM+遥感数据在该区域展开了遥感矿产地质特征解译和遥感蚀变信息提取等工作,通过类比多龙铜矿成矿要素和预测要素,综合分析得出"线、环、带及蚀变信息"为该区遥感找矿要素,据此在研究区圈定出8个找矿远景区。
Kahucuo is located in the west part of the third porphyry copper belt-the Bangong Lake-Nujiang metallogenic belt in Tibet, which possesses enormous resource potentiality and where large-scale copper-polymetallic deposits, such as Duolong, Oaerqiong, had been discovered in recent years. In order to further expand its copper mine resources, this paper interprets remote sensing geological characteristics of mineral products and extracts remote sensing altered information using ETM＋ remote sensing data in this area. By comparing the metallogenic elements of Duolong copper mine and prediction elements and through an integrated analysis, the paper concludes that ＂line, ring, belt and altered information＂ are the remote sensing prospecting elements, and delimitates eight prospective areas of mineral exploration.
