The position of Akkaşdağ? mammal locality in the neo-tectonic framework of Çank?r? basin, Turkey

Abstract

This paper presents tectonic features of the southern part of Çank?r? basin where is located the rich late Miocene mammal locality of Akkaşdağ?. Field observations and mapping demonstrated that the late Miocene-Pliocene deposits unconformaly overlie the pre-Neogene basement. The overall thickness of Neogene deposits increases toward NE. Horst-graben structure of pre-Neogene basement indicates that the Miocene fill took place under extensional tectonics which enlarged the basin toward SW. © Publications Scientifiques du Muséum national d'Histoire naturelle, Paris. © 2008 Elsevier B.V., All rights reserved.
