西昆仑卡拉库鲁木杂岩体地质及成矿特征

Geological and Metallogenic Characteristics of Kalakulumu Complex Body in West Kunlun

通过分析卡拉库鲁木杂岩体的岩相、岩石矿物、岩石化学、稀土元素特征,说明杂岩体形成环境特殊,岩性特征复杂,变形变质强烈,为复式杂岩体;岩体的成因在主体上属壳熔型至壳幔混合型。杂岩体边缘接触带地层中分布着数个多金属矿(床)点,多金属矿的形成和杂岩体有一定的时空关系,可能为一些矿产的形成提供了成矿物质来源。

By analyzing Kalakulumu complex rock mass＇s lithofacies,rocks and minerals, petrochemistry and REE, illustrated that the rock mass has special formation environment, characteristics of complex lithology, deformation and metamorphism strongly,it belongs to a multiple complex rock mass. The main cause of the rock mass is crust melted type or crust-mantle mixed type. The contact zone＇s strata which located in edge of the rock mass distributed several polymetallic deposits （mine points）. There is a certain genetic relationship which contains time and space between polymetallic ore formation and complex rock mass. Complex rock mass may provide a source of ore materials for the formation of some minerals.
