Application of remote sensing technique to detect and map iron oxide, clay minerals, and ferrous minerals in Thai Nguyen Province (Vietnam)

Abstract

This article presents a study on the application of remote sensing techniques to detect clay minerals, iron oxide and ferrous minerals using LANDSAT 7 ETM+ multispectral images. We used band ratio method to determine areas that are rich and poor in mineral composite content. The results obtained in this study can be used to create a distribution map of clay mineral and iron oxide, and to facilitate mineral mining and exploration.
