Abstract:

In view of the problem that single remote sensing data can’t meet the demand of geological prospecting, this study combines radar data, optical data and other non-remote sensing data to serve geological prospecting in the Shanyangba area, Gansu. Firstly, we utilize ASTER multispectral remote sensing data with vegetation suppression method and feature vector principal component analysis to extract alteration information in the study area. Then, PALSAR radar data is applied to extract tectonic information and produce radar intensity maps from a series of processing methods including focusing, multi-viewing, filtering, radiometric calibration, geo-coding and enhancement processing. Finally, remote sensing, geological and geochemical information are integrated in the GIS platform and help to delineate the prospecting target area of exploration, which is consis-tent with a gold ore spot found in field work. The prospecting results show that the comprehensive prospecting method using radar data, optical data and other non-remote sensing data are effective and can be important guidance for gold prospecting in this area.
