对古元古代吕梁群主变质作用进行了变质带的重新划分，划分出绿泥石带，黑云母带，石榴石带，十字石蓝晶石带和矽线石带五个带。指出变质作用属于中压相系，并认为主变质带是由近南北向的挤压—逆冲作用导致。吕梁群主变质作用是整个华北中部吕梁期（１８００Ｍａ）构造—变质—岩浆活动的一部分。
The metamorphism of the Lvliang group of the Paleoproterozoic metamorphic belt was re-divided into five zones: chlorite belt, biotite belt, garnet belt, apatite kyanite belt and silliman belt. It is pointed out that the metamorphism belongs to the medium-pressure facies system and the main metamorphic belt is caused by the squeezing-thrusting near the north-south direction. The main metamorphism of Lvliang Group is a part of the tectono-metamorphic-magmatic activity in the Lüliang Period (1800 Ma) in central North China.
