Abstract
Through an analysis of geological data of the Yangjiazhangzi and Lanjiagou Mo-polymetallic deposits,the main ore-control factors such as strata,magmatic rocks,structure and alteration were determined.Taking into account geological response to these ore-control factors in remote sensing images and making use of filter,ratio and other related methods,the authors extracted structure linear,alteration,and other information.Subsequently,an analysis of the weight of evidence and a test of independence(X2) of basic geological elements and information in remote images revealed that ore-control factors chosen are reasonable from mathematical and geological viewpoints.The above study led to the delineation of two new prospective areas.
