双变质带是地球岩石圈板块构造运动产生的重要地质图象,高压低温变质带是大陆上开展板块构造研究的重要目标。它是大洋板块在岛弧和大陆边缘之下俯冲形成的。蓝闪石及其共生矿物的存在是鉴别高压变质岩石产出的标志。板块构造理论问世以来,区域成因岩石学和板块构造矿物学有很大发展。这个理论引进我国十余年来,高压变质带(即高压低温变质带,下同)作为板块构造研究的一个重要方面也取得了成果。本文着重论述我国这方面研究情况,并对蓝闪石、冻蓝闪石的有关问题进行介绍和讨论。
The metamorphic belt is an important geological image produced by the tectonic movement of the Earth’s lithospheric plate. The high-pressure and low-temperature metamorphic belt is an important target for carrying out plate tectonics on the mainland. It is a subduction of oceanic plate beneath the island arc and continental margin. The presence of glaucophane and its symbiotic minerals is a hallmark of identifying high-pressure metamorphic rocks. Since the advent of plate tectonics theory, regional genesis of petrology and plate tectonics have greatly developed. This theory was introduced into China more than 10 years ago, the high-pressure metamorphic belt (ie, high-pressure and low-temperature metamorphic belt, the same below) as an important aspect of plate tectonics also achieved results. This article focuses on the research situation in this area in our country, and introduces and discusses the related problems of glaucophane and glaucophane.
