摘要: 在北昆仑库尔良的西邻库地发现有铜(镍)硫化物矿,未见北昆仑地区发现铜(镍)硫化物矿的报导.1999年以来,在北昆仑地区晚古生界中上石炭统库尔良群中发现了基性岩浆岩带.该岩带位于北昆仑晚古生代沟弧带内,长达40km,岩石类型为辉长岩.在基性岩体中已发现铜(镍)硫化物矿(化)体多条.主要铜矿体长度1200m,厚度2.5~8.6m,铜品位0.27%~1.53%,平均品位0.70%,矿化主要集中于岩体下盘,呈透镜状产出,走向与岩体基本一致.经预测本区有寻找大型岩浆熔离型硫化物矿床的远景.Abstract: So far,sulfide ore of copper (nickel)was discovered on the west of Kudi in Kuerliang of the North Kunlun,but no one got the report that the ore was found in the area of North Kunlun.After 1999, the basite zone was found in the Kuerliang Group in Mddle-Upper Carboniferous,in the Late Paleozoic strata of the North Kunlun area.This zone is located in the north part of Kunlun which belongs to the late Paleozoic trench-arc zone.The length reaches 40 km and the rock type mainly is gabbro.The length of the main copper orebodies is 1 200 m and its thickness 2.5-8.6 m.The copper ore grade is 0.27%-1.53% and its average grade about 0.70%.The mineralization mainly concentrates in the lying wall of the rock body.The occurrences are lens-shaped and the its tend is essentially in agreement with the rock body.The region has the hopeful potential for finding large-scale sulfide deposits of magmatic segregation style by estitration.
