摘    要:鲁东碰撞带是秦岭一大别碰撞带的东延部分,它由元古字变质地层混杂堆积体、花岗质片麻岩、榴辉岩、超镁铁质岩、镁铁质岩、麻粒岩及韧性剪切带组成。碰担带内存在一对平行展布的高压变质带-内部为榴辉岩带,边部为麻粒岩带。碰撞带形成于8.5亿年左右,3.2-3.5Ma和2.05-2.13Ma分别发生强烈活动,形成大规模推覆构造和走滑性韧性剪切构造。

Abstract:The eastern Shandong collision zone is an castern extension of the Qinling-Dabie cullisionzone between the Sino-Korcan and Yangtze cratons,which consists of the Proterozoicmetamorphic melange accumulation,granitic gneisses,eclogites,ultramafic rocks,mafic rocks,granulites and ductile-shear zones,There is a pair of parallel high-pressure meta-morphicbelts with in the collision zone in which the eclogite belt is distributed inside the zone and thegranulite belt on the margin. The collision zone was formed at ca.85OMa ago and laterexperienced strong movements at 300Ma and 200Ma ago respectively
