| 中文摘要: |
| 嘎仙镍钴铅锌矿床的形成与镁质超基性岩密切相关。已发现的低品位、大规模镍矿体,产于主岩体的中间或下盘部位。其产状、规模、形态,依附岩体而变化,并严格受岩体控制。嘎仙含矿蚀变岩体,具有镍钴元素含量偏高、低S、贫Cu、PGE含量较低(局部有偏高)现象,成矿特征具有特殊性。据现有资料分析认为,矿床成因类型应属岩浆熔离—热液改造型硫化物镍矿床。 |
| 英文摘要: |
| The form of Gaxian nickel-cobalt-lead-zinc deposit was closely related to the magnesian ultrabasic rock. The lowgrade, large-sized nickel ore body mainly occur in the middle or the lower parts of the ultrabaic rockmass. Its occurrence, size and shape were strictly controlled by the rock.The mineralized and altered rocks have rich nickel and cobalt elements, poor of copper element, low sulfur and PGE contents. The metallogenic characteristics is unique. According to existing data,it is thought that the deposit genesis can be classified into magmatic liquation and hydrothermal reformation type deposit. |
