摘　　要：降压变质反应是一个重要的变质反应类型.降压组合的生长和降压变质反应的发生和进行,与变质地体的构造过程密切相关.本文介绍了与降压交质组合有关的一些特征显微结构,分别讨论了有关Al_2Sio_6多形变体、董青石和斜长石等特征矿物的降压组合类型及其相应的降压变质反应形式.The decompressive metamorphic reactions are a type of important metamorphic reactions. The growth of decompressive mineral assemblages and the development of decompressive metamorphic reactions are closely associated with the tectonic processes. This paper introduces some characteristic microstructures of the decompressive mineral assemblages and their corresponding decompressive metamorphic reactions related to Al2SiO5, cordierite and plagioclase, respectively.
