摘　　要：景谷县大独田至一厂铜矿体赋存于三叠系中统宋家坡组(T_(2)s^(3))火山碎屑岩、熔岩中,呈似层状、透镜状、脉状产出。本文针对矿区铜矿体采用三维地质软件建立三维模型,并采用地质统计学中距离幂次反比法对矿区资源量进行估算,利用传统的垂直断面法可以作为资源量对比验证的方法之一。Yichang Cu orebody of Dadutian,Jinggu is stratoid,lenticular,veined in Middle T Songjiapo Formation(T_(2)s^(3))volcanic clastic rock,lava.In this paper,we have set up the 3D model of Cu orebody by 3D geological software and assessment of orefield resources by geostatistical medium distance power inverse ratio,The traditional vertical section method can be used as one of correlation confirmation method.
