新疆若羌县红柳沟南部地区遥感地质解译与成矿预测

Remote Sensing Geology Interpretation and Metallogenic Prediction of the Southern Area of Hongliugou, Ruoqiang County, Xinjiang

研究区位于阿尔金山脉北缘金雁山支脉的北坡,地处塔里木地块与柴达木地块接合部位,具有优越的成矿地质背景和巨大成矿潜力。研究区属于高山区,野外地质工作难于开展,因此在该地区开展遥感找矿的研究是一种经济、便捷、有效的勘查手段。通过运用影像纠正与配准、彩色合成处理、图像增强处理、数据融合以及遥感异常信息多层次筛选技术、地质信息综合分析等方法,提取与成(控)矿作用相关的蚀变异常信息和构造信息,确定了基于蚀变异常与断裂构造、环形构造信息的典型矿物遥感找矿模型并进行了成矿预测。

The research area is located in the north slope of the Jinyan Mountain offset on the north margin of Altun Mountains, which is the joint position of Tarim block and Qaidam block, so it has superior metallogenic geological background and great metallogenetic potentiality. Because the research area is in the mountainous area, it is difficult to carry out field geological work. So it is an economic and effective way to do RS prospecting research in the area. Through image correction and registration, color composite processing, image enhancement processing, data fusion, multilevel RS anomaly information filtering technology and comprehensive analysis of geological information, the alteration anomaly information and construction information related to mineralization and ore control is obtained and the typical mineral RS prospecting model based on alteration anomalies and fracture structure, circular structure is determined and metallogenic prediction is carried out.
