遥感在贵州沉积矿产资源调查中的应用

Application of Remote Sensing (RS) to the Survey of Sedimentary Mineral Resources in Guizhou

沉积矿产 ,在遥感影像上主要是通过含矿地层的识别予以鉴别的。而地层在遥感影像上的反映与其所形成的地貌具有非常大的关联。可以说地貌的形态是沉积地层及沉积矿产识别的一把万能钥匙。沉积矿产的形成无疑是受沉积环境的控制。但其保存必然受制于地貌发展演化过程。而地貌在遥感影像上是较易判别的地质形态 ,由此可建立沉积岩区遥感找矿模式。

Mostly by means of identifying the ore-bearing stratigraphy, the sedimentary mineral resources are distinguished from the images of remote sensing (RS). The strata reflected in the RS images bound up with their formed landform. Serving as a regular factor of discriminating the sedimentary strata and minerals, the geomorphologic form is indispensable. Apparently, the formation of sedimentary minerals is under control of the depositional environment, but the preservation of which is predominated by the geomorphologic evolution. Therefore, the prospecting model of RS to the sedimentary zones may be built up since the geomorphy is an easily selective geological appearance.
