Abstract:Focusing on the issue of metallogenic information asymmetry, a new method of metallogenic information integration based on combination domains was proposed, and an instance study of manganese resources prediction using the linear regression analysis was made by taking the Western Guangxi—Southeastern Yunnan areas as an example. Through the field analysis method of metallogenic information, some kinds of geological metallogenic informations were extracted, and the index set of metallogenic prognosis in the West Guangxi—Southeast Yunnan was built. Considering the issue of metallogenic information asymmetry between the model area and the prediction area, the prediction model of manganese resource was built using the linear regression analysis based on the integration of combination domains. The instance study indicates that the linear regression model based on integration of combination domains can be used to predict the manganese resource more precisely and effectively, which can resolve some issues of metallogenic information asymmetry, and the prediction results have indicative significance to the further predicting.
Key words: metallogenic information; combination domains; linear regression; metallogenic information asymmetry
