红河流域遥感地质综合解译与找矿前景分析

Remote Sensing Geological Interpretation and Uranium Prospecting Perspective Analysis of the Red River Basin

指出了红河流域地区处于特提斯构造成矿域与西太平洋构造成矿域的接合部位,地质构造比较复杂,矿产资源丰富。为加速红河流域地带找矿工作的突破,以SPOT5、ALOS和ETM+等多源遥感数据为信息源,重点提取了地层、岩浆岩、断裂构造和环形构造等成矿信息,并综合分析了已有的大地构造成矿背景、区域矿产资料、矿化点的矿化物和物化探等地质资料,利用MapGIS平台开展了遥感数据的地质综合分析和找矿前景预测,针对国内部分提出了10处找矿远景区,为该区域进一步找矿工作提供了线索,对矿产资源勘查和资源评价等方面具有一定的参考价值。

The Red Rivet Basin is in the junction of the Tethyan tectonic and western Pacific tectonic metallogenic fields, and the geological structure is more complicated with abundant mineral resources. In order to accelerate the prospecting work of the area, the source data sueh asSPOT5, ALOS, ETM＋ and other multi-soureeremote sensing data are used as the information source, and the metallogenic information such as strata, magmatic rock, faultstructure and ring structure are extracted. This paper comprehensivelyanalyzedthe existing tectonic mineralization background, regional mineral data, mineralization of mineralization and geochemical exploration and other geological data. Based on the MapGIS platform, this paper comprehensivelyanalyzed thegeologiealremote sensing data and pre- diction of prospecting foreground. The10 prospecting areas for domestic partsprovides clues for further prospecting in the region and has some reference value in mineral resources exploration and resource evaluation.
