摘　　要：龙泉关韧性剪切带由五台期韧性剪切带和吕梁期韧性剪切带复合而成 ,五台期韧性剪切带形成于低角闪岩相环境下 ,吕梁期韧性剪切带形成于绿片岩相环境下。两期韧性剪切带对五台期和吕梁期变质建造具有明显的控制作用 。The Longquanguan ductile shear zone is composed of ductile shear zonre of Wutai period and Luliang period ,The ductile shear zones of Wutai perios is formed in lowamphibolite facies. The ductile shear zones of LuLing period is formed in greenschist facies.Metamorphic formation of Wutai period and Luliang period show under the controlled of Longquanguan ductile shear zones.
