摘　　要：文章提出了构造地层单位中“岩群 -岩组 -岩段”和“片麻岩套 -片麻岩”实质上就是正常的“群 -组 -段”或“超单元 -单元”与杂岩之间的过渡类型。以此认识为基础 ,根据变质岩系遭受改造和再造作用的主因、方式、强烈程度以及原岩类型等的不同 ,把构造地层单位划分为两大套 4种基本类型 ,并对其鉴别标志、等级体系划分等予以总结和探讨。This paper proposed that “group complex-formation complex-lithomember' and “gneissic suite-gneiss' in Tecto-lithostratigraphic units belong to mid-types of units between “group-formation-member' or “superunit-unit' and “complex'. According to differences of mechanism, manner and strong degree in transformation and retransformation, tecto-lithostratigraphic units of the metamorphic rock series can be divided into two sets and four basic types of units. Besides this paper summarized and discussed distinguish criteria and the rank unit systerm's division of tecto-lithostratigraphic units.
