Abstract

Non-metamorphic Devonian units of different litho-types and of different paleogeographic origin in Turkey are parts of thick Paleozoic sedimentary successions of the Pontides, Taurides and the Arabian Plate. A broad overview about the Devonian of Turkey resulting from numerous previous studies is given by Yalç›n& Y›lmaz (2010). Devonian rocks of Gondwanan origin are represented as deposits of the Arabian Plate in Southeastern Anatolia and along the entire mountain belt of the Taurus in southern Turkey. At present, both terranes are separated from each other by an Alpine suture zone, the Bitlis-Zagros Orogenic Belt (fiengör and Y›lmaz, 1981). However, during the almost entire Paleozoic they were parts of a continuous terrane at the northeastern margin of Gondwana. The continuity of the Paleozoic units in Southern Turkey, which were deposited on the northern margin of northeastern Gondwana, ended at the beginning of Mesozoic due to the opening of the Neotethys Ocean. The southeastern part of the former Paleozoic terrane remained on the northern margin of the Arabian Plate to the south of the new ocean, while the Taurus and Menderes Blocks attained a position north of it. Closure of the Neotethys Ocean by subduction and subsequent collision led to imbrication of the Menderes-Taurus Block and many slices were thrust onto each other. Thus, collision-related tectonics resulted in the complex structure of the Taurides and a very complicated geology.
