Abstract

Data reported here demonstrate that the Misis Complex of southern Turkey comprises a major olistostromic body, formed prior to the early Miocene and tectonically emplaced upon a structurally imbricated pile of deep and shallow marine sediments of early Miocene to Pliocene age. Magmatic rocks forming olistoliths in the Misis Complex have a back-arc geochemical signature, and variations in the facies, paleoenvironments, and paleotransport vectors within the associated sediments provide a record of Miocene collisional events in southeast Turkey. The pseudo-accretionary imbrication and structural style of the Misis Complex are attributed to continued collisional over-thrusting, but there is evidence within the imbricated stack of late sinistral strike-slip faulting that relates to post-Miocene inception of motion along the East Anatolian fault system. The new data favor these geodynamic models proposed for the Neogene evolution of the northeastern Mediterranean that involve oblique convergence and associated strike-slip adjustments.
