Abstract: Based on existing study on regional metallogenic characteristics and typical deposits in Guangxi, we not only summaried systematically geology, geochemistry and remote sensing features of accumulative type bauxite mineralization in this area, but also deeply analyzed major ore-controlling factors. Thus, regional metallogenic model is set up. We've got comprehensive localization and quantitative estimation of accumulative type bauxite in Guangxi by GIS-based deposit modelling comprehensive geological information prediction method. The conclusion is as follows: 102 minimum tracts are given out, and potential resources amount to about 303 million tons, which has highly indicative significance for further ore-prospecting of this type.
