【摘要】 麻粒岩是地球中最重要的岩石类型之一。它的形成主要受地热条件的控制。麻粒岩的形成可以与大陆碰撞、大陆拉张以及大陆弧模式相联系。麻粒岩在某种程度上,还是下地壳的同义词。通过麻粒岩地体以及火山岩中麻粒岩捕掳体的研究,使人们对地球深部的物质组成和结构有了直接的了解。麻粒岩在陆壳的形成和演化中具有举足轻重的地位.陆核说、陆壳垂直增生或横向增生说,都以麻粒岩作为重要的岩石学依据.更多还原

【Abstract】 The granulite is one of the most important rocks in the earth.Its formation was controlled mainly by the condition of terrestrial heat.Their main formation models are related to continental collision,continental extension and continental arc.In some extent,granulite is the synonym of the lower continental crust.By research of granulite terranes and granulite xenoliths in volcanic rocks,composing and structure of deep substance in the earth could be realized directly. Research of granulite is a key point to understand formation and evolution of continental crust.更多还原
