川西北壤塘成矿带遥感找矿模式及找矿方向

Remote Sensing of Exploration Model and Orientation of Rangtang Metallogenic Belt in Northwest of Sichuan Province

四川省西北地区(川西北)是我国岩金矿床分布的重点地区之一,尤以微细浸染型金矿床为主。该区大中型和超大型金矿(如刷经寺、联合村、嘎拉、金木达等)显示了金矿成矿的良好前景。随着遥感技术的发展,遥感已成为重要的找矿方法之一;相比其他的地质勘探方法,遥感技术在地质找矿中所起的作用越来越显著。在对区域成矿规律和成矿条件认识的基础上,充分利用遥感技术,在NW、EW和近SN向建立区域成矿模型;优化蚀变信息的提取,并建立区域遥感找矿模型,综合遥感、地质和化探进行了综合预测选区。

Northwest of Sichuan province is one of the main distributing area of primary gold deposit, minuteness disseminated gold deposit as the main type deposit. Large and middle gold deposit and super large gold deposit in this area （ like Shuajinsi Lianhecun, Gala, Jinbuda） indicated the fine foreground of gold metallogeny. As the development of the remote sensing technology, remote sensing had become one of the important ways of exploration. Compared with other normal methods of geological survey, remote sensing played an obvious role in geological survey gradually. Based on the regional metallogeny and metallogenic condition, using remote sensing built regional tectonic framework which based on the NW, EW and near SN. It can optimize the abstraction of alteration information, and built regional remote sensing exploration model. Than we chose the synthetic prediction atea, integrated with remote sensing, geology, geochemical prospecting.
