新疆西南天山矿物变质特征研究

Study on the metamorphic characteristics of minerals in the Tianshan Mountains,southwest Xinjiang

西南天山矿化带是我国矿物变质带之一,长期以来被诸多学者关注,近年来一大批学者相继对其进行了矿石矿物学、地球化学及年代学等方面的研究,揭示了变质带的成因及构造演化、变质带的划分,变质期次的划分,俯冲折返机制,以及对磷灰石、金红石等副矿物的研究,都得到了重分的展开。但是对于俯冲带折返侵位的动力学过程、诱因等还需要进一步的研究。

The Tianshan mineralized belt in Southwest China is one of the mineral metamorphic belts in China,which has been concerned by many scholars for a long time.In recent years,a large number of scholars have carried out research on its ore mineralogy,geochemistry and chronology,etc.,revealing the genesis and structural evolution of metamorphic belt,the division of metamorphic belt,the division of metamorphic period,the mechanism of subduction and exhumation,as well as the accessory minerals such as apatite and rutile The study of things has been carried out in terms of dichotomy.But the dynamic process and inducement of subduction zone exhumation and emplacement need further study.
