摘要: 大别山北部的变质复理石推覆体属华北大陆板块南部的盖层推覆体，主要包括佛子岭群和卢镇关群。其时代主要为震旦纪—早古生代至泥盆纪。变质作用主要为角闪岩相—绿片岩相，在靠近变质蛇绿混杂岩带附近的部分（佛子岭群）可能曾经因卷入变质蛇绿混杂岩带而有过麻粒岩相或榴辉岩相（？）变质作用。变质复理石推覆体中岩石变形强烈，但不同地段变形程度不等。
Abstract: The meta flysch nappe in the north part of the Dabie Mountains is composed of the Foziling Group and Luzhenguan Group. Located to the north of the meta ophiolite mélange, it belongs to the cover of the south part of the North China continental plate. Its age is Sinian early Paleozoic to Devonian. The metamorphism is mainly of amphibolite and greenschist facies, and it is inferred that near the metaophiolite mélange （the Foziling Group） metamorphism of granulie or eclogite facies might have occurred. The rocks in the meta flysch nappe are intensely deformed, but the grade of deformation differs somewhat from place to place.
