摘　　要：矿床位于哈萨克斯坦-准格尔板块准格尔微板块哈尔里克古生代岛弧带的小铺前震旦纪隆起区。矿体呈似层状、透镜体状顺层产出。金红石为矿床最主要含钛矿石矿物。通过对区内矿石及围岩特征及化学成分研究认为:斜长角闪岩的原岩为富铁镁的火山-基性岩浆建造,富含钛等有益组分,为金红石矿形成提供了物质来源。经过长期中高压变质作用,形成金红石钛矿床。综合分析认为:矿床成因类型属于火山-基性岩浆建造中高压变质型金红石钛矿床。The deposit is located in the Xiaopu pre Sinian uplift area of the Harlik Paleozoic island arc belt of the Jungar microplate of the Kazakhstan Jungar plate.The ore body is layered and lenticular and occurs along the layer.Rutile is the main titanium bearing ore mineral in the deposit.Through the study on the characteristics and chemical composition of ore and surrounding rock in the area,it is considered that the original rock of amphibolite is a volcanic basic magmatic formation rich in iron and magnesium,rich in titanium and other beneficial components,which provides a material source for the formation of rutile ore.Rutile titanium deposit was formed after long-term medium and high pressure metamorphism.The comprehensive analysis shows that the genetic type of the deposit belongs to the rutile titanium deposit of medium high pressure metamorphism in volcanic basic magmatic formation.
