Abstract: Based on the GIS-data-driven model in combination with the weights of evidence and basic geological data, the information on the relevant structure, alteration and mineralization can be extracted from remote sensing images to evaluate the resource potential quickly. The Mo-polymetallic deposit in West Liaoning were thus evaluated with 8 factors, i.e., the upper Cambrian-Ordovician, Yixian formation, Wumishan formation, Yanshan-period granite, alteration of clay, intensity of Fe²⁺, intensity of Fe³⁺ and tectonic intensity. Such an evaluation is feasible as proved mathematically by X² independence test, and its results conform to the three existing deposit-concentrated areas. Gaojialing and Hongyazi were predicted to be the two mineralogenetic areas.
