Abstract: Geography data are multi-sources, complex expression, indirect character, multi-solution, non-linear and got-up sort of original mineralized belt is uncertainty. To solve the problems above mentioned, the Self-Organizing Feature Map was used to execute the non-linear conformity of the complex geography information, then analyze and sort the geography exploration materials were analyzed and classified. This method is effective; the result of classification conforms to the geography fact. Then it fetches up the deficiency of the got-up sort and also provides trustiness bases for the partition of the mineralized belt. 
