Abstract

To promote uranium exploration in Chaganhada and provide remote sensing alteration anomaly information, this paper extracted chlorite alteration and iron-strained alteration by principal component analysis on the basis of analysis of wall rocks related to uranium mineralization and spectral characteristics of the typical alteration minerals in WorldView-3(shorthand for WV-3 in the following) bands. Then, the alteration information extracted was made processing on the ArcGIS platform, and an integrated anomalous information figure was compiled. The results of field verification show that the alteration anomaly information which extracted from WV-3 data is consistent with the reality. And the alteration anomaly information should be taken as one of the important clues in the uranium exploration in this area.
