The Mesozoic Stratigraphy and Ammonite Faune for Niksar-Erbaa (Tokat) Territory

Abstract

The basement of the study territory covering the Niksar-Erbaa territories and their immediate vicinity, located on the north and above the North Anatolian Fault, forms the rocks belonging to Permo-Triassic aged Karakaya Complex . The Mesozoic units forming the primary cover rocks in the region consist of the Upper Jurassic-Lower Cretaceous aged Titonic facies developed Calpionelli limestones, Upper Cretaceous aged tuffs and rugged rocks. Mesozoic formations begin with Liassic sandstones, mudstones and limestones, which come transgressively with angular unconformity over the basement rocks. The Tertiary-Berriyan aged units with titanic facies bearing the ages of Cenomanian-Maestrichtian aged units started with agglomerates and reddish-colored, firmly adherent conglomerates. Upper Cretaceous units continuing with carbonate-cemented polygenic sandstones, variegated colored carbonate marl-mudstone plies and their partially metamorphosed derivatives and recrystallized limestones are terminated by sandstone-marl-limestone intercalations, including volcanic intercalations developed in basaltic-andesitic dykes . In the pelagic mudstones belonging to the unit,  Pentacirinus sp. and Belemnit fossils have been also identified in addition to such Ammonites sp., Phylloceras sp., Oxycerites sp., Sphaeroceras sp., Ausseites sp.. It is unconformably overlain by shallow marine units consisting of limestones and limestone-sandstone alternations of Paleocene-Lower Eocene aged Nummulitic limestones forming the second cover units of the area. In the neotectonic period, sedimentary rocks of Pliocene aged are deposited in the sedimentary areas formed by the formation and development of the North Anatolian Fault. The youngest units of the region are the Pleistocene aged young basalt formations and Quaternary aged alluvium, slope rubble and accumulation cones.
