| Abstract: | A synthetical study has been performed on the mineralization possibilities of porphyry rocks,geochemical characteristics and other metallogenic information in Yulong copper ore belt.On the basis of this study,some marker metallogenic variables are optimized and a mathematical model for ore prospecting is proposed.On the condition that the mathematical model statisfies the need of an extending model,association similarity indexes of the mineralized porphyry bodies and prospecting areas are calculated from the marker metallogenic variables and their corresponding power coefficients of the prospecting areas,and Ceqinla,Zunxi and Namazhuoba areas are optimized as ore prospecting target areas based on fiducial interval values of the mineralized porphyry bodies in the ore belt. |
