| 摘 要： | 超高压变质作用是指在地温梯度小于１０℃／ｋｍ条件下发生的高于“石英－柯石英”相变线压力的变质作用，一般发生在陆－陆碰撞造山带深部。由于其生成条件特殊，超高压变质岩中存在着金刚石、硬玉、蓝晶石及金红石等潜在的矿产资源。

| Abstract: | Ultrahigh-pressure(UHP) metamorphism is characterized by both low T/P gradient (about 10 C/km or less) and P-T regime higher than quartz -coesite equilibrium. UHP rocks have been reported so far all from continent-continent colli-sion zones. During the UHP metamorphism, mineral resources, such as diamond, jadeite, kyanite, and rutile, might form. |

| Keywords: | UHP rocks collisional orogenic belt potential mineral resources |
