中亚吉尔吉斯斯坦、塔吉克斯坦遥感找矿预测

Remote sensing-based prospecting prediction for Kyrgyzstan and Tadzhikistan in Mid-Asia

基于ETM,ASTER卫星遥感数据在中亚吉尔吉斯斯坦、塔吉克斯坦及我国周边地区开展的1︰100万遥感地质矿产解译,是在前人研究成果基础上,对该区进行大地构造格架遥感解析,提取区内主要断裂构造和与成(控)矿作用相关的地层、构造、岩浆岩、蚀变信息,并根据控矿地层、控矿岩体、蚀变异常与线环构造等信息建立典型矿床遥感找矿模型;以找矿模型为指导,结合矿床类型、成矿地质背景、主要控矿和成矿要素、遥感地质解译信息、遥感异常信息等多源信息对研究区进行成矿预测及战略选区。

Based on the previous result we make remote sensing （ETM,ASTER） data interpretation of geology and mineral resources of Kyrgyzstan and Tadzhihistan and surroundings of China at scale 1 ： 1 million. Geotectonic frame of the area is interpreted and information related to ore （mineralization）-con- trol and the mineralization, such as stratum, structure, magmatic rock and alteration zone extracted. Re- mote sensing prospecting model of typical ore deposit is built on basis of ore-control stratum and rock body, alteration information and linear and ring structures. Integrated with geological and metallogenic background the model is applied to ore prediction and selection of strategic targets.
