Анотация: Mineral prospectivity mapping (MPM) techniques can integrate and analyse these digital geologi- cal, geochemical and geophysical dates sets to produce maps that identify where optimal conditions converge. In this study we assessed weights-of-evidence, which relates to the data-driven method with using an application in the prediction of Cu mineral occurrence in the West part of Dananhu-Tousuquan arc, NW Xinjiang, China. Weights-of-evidence methodology combines spatial data from different sources to describe and analyzing inter- actions, provide support for decision makers and make predictive models. The results of mineral prospectivity mapping achieved by weights-of-evidence techniques are shown in posterior probability map. Based on the com- bination of the binary predictor maps, the high favorability districts, the permissive districts, and the not permissivedistricts occupy 1.94%, 1.92% and 96.13% of the study area, respectively. Detailed analysis of the case study has been performed to promote this area as potential targets and to demonstrate the ability of prospectivity modeling techniques as useful tools in mineral exploration programs.
