摘　　要：矿权区位于Kaapvaal-Zimbabwe-Limpopo铜镍多金属成矿带上,铜镍矿点星罗棋布,在矿权区内的超基性岩体中的东西向断层种发现了脉状铜镍矿体地表长约800m,宽约1.2~3m,对矿体倾向延伸有一定的指导意义;根据化探综合异常图,铜镍异常的分布和超基性-基性岩体的分布基本扣合,根据岩浆岩的成矿专属性,工作区超级性-基性岩体分布有一定规模,在岩体内寻找分异性铜镍矿比较有前景;在遥感解译的羟基异常区和化探异常金铜异常比较扣合,在该异常内寻找铜金矿床有一定的前景。The target PL584 in the Tsetbjwe Region,Botswana lies in the Kaapvaal-Zimbabwe-Limpopo Cu-Ni-polymetallic metallogenic belt.A Cu-Ni mineral vein with an outcropping length of about 800 m and a width of 1.2-3 m occurs in a latitudinal fault of an ultrabasic intrusion.Cu-Ni geochemical anomalies coincide with spatial distribution of the ultrabasic intrusion.The hydroxyl anomalies interpreted by remote sensing coincide with Au-Cu geochemical anomalies.Accordingly,the target PL584 is of good perspective for searching for Cu-Ni deposit and Au-Cu deposit.
