摘要
柳城子沟脑多金属矿位于敦煌(地块)Au-磷-芒硝成矿区,阿克塞-好不拉元古代(华力西期)铅锌金铁成矿带。矿体主要赋存于太古宇~古元古界敦煌岩群(ArPtD)白云石大理岩中,后期岩浆活动为该区提供了热源和成矿物质,阿尔金大型断裂从本区通过,次级断裂发育,形成近东西构造蚀变破碎带较多,为该区多金属成矿提供了良好的运移通道和赋存空间,矿床成因可属中低温热液裂隙充填型矿床。
Liuchengziguonao polymetallic ore is located in Dunhuang(massif)au-p-glauberite metallogenic area,Aksai wunla Proterozoic(Variscan)Pb Zn Au Fe metallogenic belt.The ore body mainly occurs in the dolomite marble of Archean Paleoproterozoic Dunhuang group(arptd).The later magmatic activity provides the heat source and ore-forming materials for the area.The large-scale Altun fault passes through the area,and the secondary fault develops,forming many structural alteration and fracture zones near the East and West,which provides a good migration channel and occurrence space for the polymetallic mineralization in the area.The genesis of the deposit can be classified as The middle and low temperature hydrothermal fracture filled deposit.
