The Late Oligocene Nappe Emplacement in the Southeast Anatolian Orogenic Belt
Three major phases of characterized by nappe emplacements have long been known in the Southeast Anatolian orogen. the correspond to the Late-Eocene, Middle Eocene, and Early Miocene. The area to the east of Van Lake displays Upper Lutetian-Upper oligocene olistostromal-turbitis unit intertongued with arc volcanites. They form the basemant together with the Yüksekova group and Lutetian are overlain by nappe which is composed of Upper Cretaceus-Eocene arc volcanic rocks and associated sedimentary rocks at the bottom, and slides including silvers of metamorphic rocks at the top. these allocthon carried above it, the upper Lutetian-Oligocene sedimentary and volcanic rock interclation. After the implacemnet the nappes were unconformably overlain by Uppermost Oligocene-Lower Miocene clactic rocks. The stratigraphical data presented here indicate a previously unknown nappe emplacement place corresponding to the Late Oligocene.
