Abstract

Abstract

This article selects Bangbangnaibeiiiqieer that is located in China's major ore concentration area in Inner Mongolia as the research area and proposes an enhanced extraction of alteration information using remote sensing, which extracts alteration information first, and then uses topographic correcting. Firstly, the area is divided according to landform, topography and rock character, and then the extracted alteration information is corrected based on topography; Secondly, alteration information is extracted combing geological data, geophysical prospecting data and geochemical exploration data. Finally, metallogenic prediction is built. This new study is better than previous study, because it can display alteration information obviously, eliminate the effects of topography and rock character, and offer a more accurate evidence for further mineral investigation.
- extraction of alteration information,
- topographic correcting,
- area division
