摘　　要：本文借助Surpac三维地质软件,利用羊拉铜矿勘探资料,实现矿床三维数学模型,空间上展示了铜矿体的层状、似层状、透镜状分布特征,结合野外观察,发现矿体下部网脉状矿石和硅质岩等,这为羊拉块状硫化物铜矿床成因提供了佐证。同时,运用数学地质方法研究了铜矿化富集规律,直方图出现的多峰分布,说明矿化具多期次叠加,与地质推断相同。According to the exploration information of Yangla Cu deposit,we have carried out the 3D mathematical model of ore deposit with Surpac 3D geological software,showing the bedded,stratoid,lenticular distribution feature of Cu orebody.In combination to the field observation,we have discovered the stockwork ore and silicalite,etc in the lower part of orebody,which provide the confirmation of genesis of Yangla massive sulfide Cu deposit.Moreover,we have also studied on the concentration rule of Cu metallogenesis with mathematical geological method,the histogram shows the multimodal distribution,which indicates the metallogenesis is in polyphasic superimpostion,similar to the geological inference.
