摘要
砂岩铜矿床的品位、吨位及空间分布具有分形分布的特征世界主要砂岩铜矿床的平均品位、吨位和品位与吨位关系的分维值分别为１．１３、１．１５和２．６７；我国南方含铜盆地和康滇地区砂岩铜矿空间分布的分维值分别为０．９１１和０．９３２利用矿床的分形模式对主要含铜盆地的砂岩铜矿远景进行了预测，结果表明滇中、滇西、会理、衡阳和沅麻等盆地还有较大的找矿前景图６，表１。
The grade,tonnage and distribution of sandstone
all show fractal structure features.The fractal dimension is 1.13,1.15 and 2.67 for average
grade,tonnage and grade vs tonnage of sandstone copper deposits in the world
respectively,and 0.911 for the distribution of Cu-bearing basins in South China,and 0.932 for the
distribution of sandstone copper deposits in Kangdian region.The prospective reserve of
sandstone copper deposits in main Cu-bearing basins is predicted using a fractal model,which
shows good prospects of ore potentiality in the central Yunnan basin,the western Yunnan
Basin,the Huili basin,Sichuang,the Hengyang Basin and the Yuanma
basin,Hunan.6figs.,1tab.,4refs.
