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... 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。 展开更多

The Wugong Mts. region may have experienced three stages of metamorphism in Early Paleo-zoic, which may be closely related to the generations of regional deformation. The first stage ismedium-pressure metamorphism, the second medium- and high-pressure one with stress on high-pressure metamorphism, and the third low-pressure and high-temperature metamorphism. Theregion, as a whole, is a Caledonian medium-high pressure metamorphic belt. 展开更多
