以滇中地区1∶20万水系沉积物区域化探扫面资料为基础,应用地球化学块体理论与方法,对研究区内Cu地球化学块体特征及层控型铜矿资源特征进行了系统分析。共圈出5个地球化学块体、10个面积相对较小的地球化学亚块体,并根据区域成矿地质背景划分为2个Cu地球化学分区。以1km矿床勘探深度为准则,计算各(亚)块体的铜金属供应量及铜矿产资源量,预测全区潜在铜矿资源总量为586.1万t。通过追踪地球化学块体谱系,揭示了元素在地球化学块体中逐步浓集成矿的轨迹,并结合区域控矿要素,确定了11个层控型铜矿成矿远景区,其中以3-1,3-2,10-1-1-1-1-1,10-1-1-2-1-1,10-1-1-2-1-2子块体的成矿潜力较大。
Based on the geochemical exploration data of the 1: 200000 sediments in central Yunnan, the geochemical block characteristics and the characteristics of stratabound copper resources in the study area were systematically studied by using the geochemical block theory and method analysis. A total of 5 geochemical blocks and 10 geochemical sub-blocks with relatively small area were circled and divided into 2 Cu geochemical zones according to regional metallogenic geological background. Based on the exploration depth of 1km deposit, the copper metal supply and the copper mineral resources of each sub-block are calculated. The total potential copper resources in the whole area are predicted to be 5.81 million tons. By tracing the pedigree of geochemical blocks, the loci of gradually concentrating mineralization in geochemical blocks are revealed. Combined with the regional ore-controlling elements, eleven stratiform copper ore prospecting areas have been identified, of which 3-1 , 3-2, 10-1-1-1-1-1, 10-1-1-2-1-1 and 10-1-1-2-1-2 sub-block have higher metallogenic potential.
