Sedimentology of The Limestone Olistoliths of the Erzincan-Refahiye Area, Eastern Anatolia
Abstract: Epicontinental ,and partly basinal limestones of the Middle Jurrasic-Lower Cretaceous together withpenecontemporaneous ophiolitic masses had been slumped down in to the sedimentary troughs ,and/ basins by thegravity slides in Upper Cretaceous time ,and, originated the limestone olistoliths which are preserved as multi-sized limestone mounds in the present ophiolitic complexes.The diagenetic ,and epigenetic changes in those limestones had followed by the dynamo-metamorphic activities wiclicaused generation of the martolized limestones ,and/ crush breccias. The prensence of the primary deposiitonal texturein the limestone olistoliths are concluded as clues of the modifying effects were superficial ,and limited.In the limestones of the study area (Rehafiye) which is one of those areas characteristics by ophiolitic olistoliths,following microfacies are discerned; a) Lime mud, b) Pelletoid lime mud, c) Mud supported (Lime wackestore), d) Grainsupported (Pack-grainstones) as "Sedimentary microfacies" ,and, e) Intermediate metamorphic (partly mar.blized limestones), f) Crystalline metamorphic (crush breccias) as "metamorphic microfacies".
