| 摘 要： | 大兴安岭古利库金矿区出露的新元古代-早寒武世落马湖群变质岩系,系一套片麻岩、片岩、变粒岩以及大理岩、板岩组合,属低绿片岩相、高绿片岩相和低角闪岩相.恢复原岩为中基性、中酸性火山岩及其碎屑岩和粉砂岩-砂岩、灰岩等.主要成矿元素Bi、Au、Ag、Hg对比大陆地壳相对富集,在遭受韧性剪切作用后,Au、Ag、Bi明显富集,As、Sb亦有富集.由此推断,落马湖群变质岩系应属矿源岩,韧性剪切作用使Au、Ag等成矿元素预富集.

| Abstract: | The Neoproterozoic-Early cambrian Luomahu group metamorphic rocks, outcropped in Guliku gold field, Daxinganling Ridge, consist of gneiss, schist, metadolerite, marble and slate,which belong to low greenschist, high greenschist and low amphibolke facies. Restoration of original rocks shows intermediate-basic and acid-intermediate volcanic rocks, fragmental rocks, siltstone, sandstone and limestone. Theain mineralizing elements, i.e., Bi, Au, Ag and Hg are relatively richer than those in continental crust. After ductile shearing, there is apparent enrichment for Au, Ag and Bi, As well as As and Sb. Thus, it is concluded that the Luomahu group metamorphic rocks should be the provenance of ore and the ductile shearing concentrates the mineralizing elements such as Au, Ag,etc. |
