大别山北部造山带变质岩地区发现新鲜的榴辉岩露头是最新发现 .这些榴辉岩产于面理化的橄榄岩中 ,外围是条带状的片麻岩 ,主要矿物成分为绿辉石、石榴子石、透辉石、斜方辉石、金红石、尖晶石、橄榄石、刚玉、石英、角闪石、斜长石及不透明矿物 ;根据岩相学的研究 ,早期的矿物组合为绿辉石 ,石榴子石 ,金红石 .大别山北部地区榴辉岩的发现 ,表明大别山北部变质岩带曾经深俯冲并且受到过超高压变质作用 ,这无论是对了解大别山北部超镁铁岩带的构造背景、大别山造山带的几何结构 ,还是对其运动学特征 ,都有非常重要的甚至是决定性的意义
The discovery of fresh eclogite outcrops in the metamorphic rocks in the northern Orogenic Belt of the Dabie Mountains is the latest discovery of these eclogites that occur in well-defined peridotites and are surrounded by banded gneiss, with major mineralogical compositions of omphacite, pomegranate Orthoclase, orthopyroxene, rutile, rutile, spinel, olivine, corundum, quartz, hornblende, plagioclase, and opaque minerals. According to the study of petrography, the early mineral assemblages are green The discovery of eclogites in the northern part of the Dabie Mountains shows that the metamorphic rocks in the northern part of the Dabie Mountains were subducted and subjected to ultrahigh-pressure metamorphism. Whether it is to understand the tectonic setting of the ultramafic belt in the northern part of the Dabie Mountains, The geometric structure of the Dabie orogen, or its kinematic characteristics, have very important and even decisive significance
