蓝闪片岩、蓝闪榴辉岩是蛇绿岩型混杂岩的重要组成部分,是板块构造消减带(俯冲带)特征标志之一。国外一些学者,如赫斯(Hess,1962)、林格伍德(Lingwood,1969),都城秋穗(Miyashiro,1972)、格罗(Grow,1973)把这些岩石和橄榄岩、玄武岩一起,看作为与构造俯冲的高压变质成因有关而产在消减带的下部。这些高压变质岩石具有特征的矿物组合并带有鲜明的构造印记。近二十年来,高压变质带岩石学的研究引起了广泛的注意,板块矿物学也被人们重视起来。在我国接连在秦岭,祁连山、河南信阳、大别山、江苏海城至赣榆
Blue flash schist and blue flash eclogite are important components of ophiolite-type melange and are one of the characteristic signs of tectonic subduction zone (subduction zone). Some foreign scholars such as Hess (1962), Lingwood (1969), Miyashiro (1972) and Grow (1973) consider these rocks together with peridotites and basalts as And the tectonic subduction of high-pressure metamorphic origin and produced in the lower part of the abatement zone. These high-pressure metamorphic rocks have a characteristic mineral assemblage with distinct tectonic imprints. In the recent two decades, the research on the petrology of high-pressure metamorphic rocks has drawn extensive attention. Plate mineralogy has also been paid attention to.
