摘　　要：本文主要介绍了中国蓝片岩的时空分布、一般地质特征和成因。内容主要包括以下6个方面:一是当前中国蓝片岩的研究概况和重要进展;二是蓝片岩、蓝闪片岩和蓝片岩相名词的讨论;三是对17个蓝片岩带的一般地质特征(主要包括原岩性质、岩石矿物共生组合,p-t条件,变质时代及赋存的大地构造背景等)进行描述;四是讨论蓝片岩带的成因,并提出深俯冲-陆陆碰撞型和深俯冲-洋壳碰撞两个模式;五是总结了几点蓝片岩带综合地质特征;六是提出了蓝片岩带研究中存在的6个地质科学问题,建议进一步加强考察与研究。The paper chiefly summarized the tempo-spatial distribution, general geological characteristics and formation of blueschist in China. There are mainly six aspects included in this paper. ①Current studying progress on bluechist belts in China. ② Discussing the concepts of blueschist, glucophane schist and glucophane schist facies or blueschist facies. ③ Describing the geological characteristics of 17 blueschist belts in China, including rock associations, nature of original rocks, mineral assemblages, p-T conditions, metamorphic ages and tectonic backgrounds. ④Analyzing the genesis of blueschist belts, and two modes of deep subduction-continental-continental collision and deep subduction ocean crust collision was proposed. ⑤ Summarizing the synthetic geological characteristics of blueschist belts in China. ⑥Six geological issues on studying blueschist belts were also proposed and further investigation and study is also suggested.
