Abstract: Abstract：Based on researches on geological features of the ore deposit, the authors carried out a systematic study of the Balao ore district to obtain useful metallogenic information. The software platform “MORPAS” was used to analyze comprehensively large amounts of geosciences multi-information in the aspects of geology, geochemistry and remote sensing. A prospecting model was set up to perform the metallogenic prediction on comprehensive information of the study area and, as a result, four prospecting targets were delineated. Certain model units were selected according to the variation regularity of the deposit value with the ore-controlling factors and their combinations so as to establish the comprehensive value of ore-controlling factors and prospecting criteria, i.e., the functional relationship between the information and the resources, and the resources of four prospecting target areas were estimated quantitatively. The evaluation of the resource potential is of important guiding significance for the next step prospecting work in the study area.
