The Metamorphism And The Relationship Between Infra And Suprastructures Of The Bi̇tli̇s Massif – Turkey, Metin Şengün
Bulletin of the Mineral Research and Exploration
The infrastructure of the massive consists essentially of amphibolites, gneisses and micaschists intruded by a biotite granite and the successive hololeucocratic phase. The mantling rocks of the suprastructure comprise metapelitic rocks unconformably underlying metacarbonates dated as Middle Devonian- Mesozoic. The infra-suprastructure boundary is interpreted as a surface of transgressive overlap. The rocks of infra and suprastructure are involved in isoclinal folds with ductile deformation along most of the boundary conclusively suggesting in situ position of the suprastructure during the Alpine deformation. The shear planes are discontinous, en echelon and run independently of the infra-suprastructure boundary. A uniform sequence of Palaeozoic …
