摘要

This paper chiefly summarized the tempo-spatial distribution, general geological characteristics and formation of blueschist in China. There are mainly six aspects included in the paper: 1) current 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; 4) analyzing 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; and 6) six geological issues on studying blueschist belts were also proposed and further investigation and study is also suggested.
