概述了目前仅有的几个发现微粒金刚石的地区如哈萨克斯坦、挪威西部和我国中部等地的超高压变质岩的最新研究成果，并指出这些变质岩中微粒金刚石为变质成因，变质流体对微粒金刚石的形成具有十分重要的意义。由于微粒金刚石的稳定区压力超过了3．5GPa，温度高于700℃，这表明盖层厚度大于100km，因此微粒金刚石代表了比柯石英更极端的高压条件。超高压变质岩石产于大陆俯冲造山带，且其源岩为先存的相对冷的地壳岩石，其折返是一个多作用多阶段的过程。
This paper summarizes the latest research results on UHPM metamorphic rocks in the areas where only microgranular diamond was found in China, such as Kazakhstan, western Norway and central China. It is pointed out that the microparticulate diamonds in these metamorphic rocks are metamorphic, The formation of diamond is of great significance. Particle diamond represents a more extreme high pressure condition than coesite because the pressure in the stability zone of the microparticle exceeds 3.5 GPa and the temperature is higher than 700 ° C, indicating that the cap thickness is greater than 100 km. EHV metamorphic rocks are produced in the continental subduction orogenic belt, and the source rocks are pre-existing, relatively cold crustal rocks. The reenforcement of UHP metamorphic rocks is a multi-stage multi-stage process.
