摘　　要：对玉龙铜矿带斑岩的含矿性、矿带地球化学特征和其他成矿信息进行了综合分析 ,在此基础上 ,优化和筛选了矿带含矿标志变量 ,建立了矿带找矿数学模型。在找矿数学模型达到推广模型要求的前提下 ,根据矿带各预测区具有的成矿标志变量及其对应的标志变量权系数 ,计算了矿带已知含矿斑岩体与预测区的关联度值 ,并据已知含矿斑岩体成矿临界值的置信区间值优选了测钦拉、遵西和那马卓巴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.
