Kinematics of a Former Oceanic Plate of the Neotethys Revealed By
PUBLICATIONS Tectonics RESEARCH ARTICLE Kinematics of a former oceanic plate of the Neotethys 10.1002/2016TC004206 revealed by deformation in the Ulukışla basin (Turkey) Key Points: Derya Gürer1, Douwe J. J. van Hinsbergen1, Liviu Matenco1, Fernando Corfu2,3, and Antonio Cascella4 • Cretaceous to Paleocene N-S and E-W extension was overprinted by 1Department of Earth Sciences, University of Utrecht, Utrecht, Netherlands, 2Department of Geosciences, University of Oslo, Eo-Oligocene shortening 3 4 fi • The geology of Central Anatolia can Oslo, Norway, Centre for Earth Evolution and Dynamics, University of Oslo, Oslo, Norway, Istituto Nazionale di Geo sica e be explained by a three-plate system Vulcanologia, Pisa, Italy in Cretaceous to Paleogene time • We reconstruct upper plate kinematics to infer subduction Abstract Kinematic reconstruction of modern ocean basins shows that since Pangea breakup a vast area evolution and relative plate and in the Neotethyan realm was lost to subduction. Here we develop a first-order methodology to reconstruct trench motions within the Neotethyan ocean the kinematic history of the lost plates of the Neotethys, using records of subducted plates accreted to (former) overriding plates, combined with the kinematic analysis of overriding plate extension and — Supporting Information: shortening. In Cretaceous-Paleogene times, most of Anatolia formed a separate tectonic plate here • Supporting Information S1 termed “Anadolu Plate”—that floored part of the Neotethyan oceanic realm, separated from Eurasia and Africa by subduction zones. We study the sedimentary and structural history of the Ulukışla basin (Turkey); Correspondence to: overlying relics of this plate to reconstruct the tectonic history of the oceanic plate and its surrounding D.
