Abstract

Abstract

Metallogenic prediction using remote sensing alteration information has been widely applied, but there is no systematic mapping method. This paper suggests a new method of isodensity map compilation of remote sensing alteration information. Following the compilation pratice of geochemical field maps, the percentage of the area of each alteration information per unit area is statistically calculated, and the contour map of the areal density is generated. During the remote sensing analysis and geological survey in Dongwuqi region of Inner Mongolia, eight metallogenic prospective areas were successfully delineated by means of this method with the inferred lineation and circular structures based on remote sensing interpretation. Compared to the traditional compilation methods based on pixel units, this new map compilation method can not only effectively enhance the small area information occurring simultaneously on various alterations, but also provide a more visual presentation of the overall spatial distribution and the concentration center of alteration information, favorable for delineation of metallogenic prospective areas and selection of places for further field investigation.
