新疆梅岭南铜锌矿床矿化强度特征及找矿预测

Characteristics of mineralization intensity and prospecting prediction in South Meiling Cu-Zn deposit,Xinjiang

新疆哈密梅岭南矿床位于东天山卡拉塔格古生代火山隆起区西南边缘的斜坡地带,矿体具有典型的"上层下脉"二元结构特征。通过提取见矿钻孔的矿体品位、厚度等相关数据信息,利用Surfer软件编制矿化强度图,通过分析矿化强度的分布特征并结合矿区地物化成果,初步认定成矿后构造在一定程度上对矿体有错断破坏作用,并认为矿区外围具有寻找块状硫化物矿床的潜力,初步圈定了两处有利的找矿靶区。

The South Meiling deposit is located in the southwestern Kalatage area in the eastern Tianslian belt of NW China. The orehodies occur in Ordovician wdcano elastic rocks with typical vertical zonation, i.e., massive Cu-Zn orebody in tile upper part and vein type orebody in lhe depth.By extracting ore grade, ore thickness and the relevant information from the mineralziaed drill holes, the mineralization intensity was mapped by using Surfer software.Through analyzing the distribution of mineralization intensity, in combination with geological, geophysical and geuchemieal information, it is thought that the orebodies were displaced and destroyed by post- mincralizalion faults. It is proposed that there is great potential for exploring massive sulphide orebodies in the surrounding area of the depusit,and two favorable prospecting target areas were delineated.
