麻粒岩是高温、高压变质相的典型代表岩石之一。对麻粒岩中造岩矿物和副矿物的分选试验研究,将有助于变质时代,变质相带,原岩恢复,变质作用机理的研究,并对提高前寒武系地质研究程度,具有重要的理论和实际意义。本文初步总结了麻粒岩中造岩矿物和副矿物的单矿物分选试验,应用此分选试验的方法和流程,获得了纯度95—98％的主要造岩矿物和副矿物,满足了单矿物测试的要求。因设备条件和分选技术水平所限,对方法和流程尚有不足之处,望批评指正。一、麻粒岩的矿物组合及分选性质组成麻粒岩的矿物达20余种。其中造岩矿物主要有透辉石、紫苏辉石、石榴石、角
Granulite is one of the typical representative rocks of high temperature and high pressure metamorphic facies. The study on the separation of granitic rocks and accessory minerals in granulite will be of great help in the study of the metamorphic epoch, metamorphic facies belt, original rock restoration and metamorphism mechanism, Important theoretical and practical significance. This paper summarizes the single mineral separation tests of granite and rock minerals in the granulite. By using the methods and procedures of this classification test, the major rock-forming minerals and accessory minerals with the purity of 95-98% are obtained, Mineral testing requirements. Due to equipment conditions and the level of sorting technology, the methods and processes are still inadequate, hope to criticism and correction. First, the granulite mineral assemblage and sorting nature of granulite rock minerals up to 20 species. The main rock-forming minerals are diopside, peridotite, garnet, angle
