“…The Akıncılar Formation is overlain by the Middle-Upper Eocene KV consist of greenish-black colored porphyritic textured basaltic trachyandesite, trachyandesite, and trachyte-containing KV, which are the basic units of this study. In addition, Kösedağ syenite has a hot-hot contact relationship with Karataş volcanic [1]. The Kösedağ syenite mainly has alkaline feldspar syenite, quartz alkaline feldspar syenite, syenite and quartz syenite and locally monzonitic composition.…”

The study area covers the eastern part of Zara district (Sivas) located in East-Central Anatolia. The units found in the region from bottom to top are characterized by the Upper Creataceous-Paleocene Refahiye Complex, the Middle-Upper Eocene Akıncılar Formation, the Karataş volcanics and Kösedağ Syenite, the Lower Miocene Onarı Formation, the Upper Miocene-Pliocene İsola volcanics, the Şerefiye volcanics, the Kadıköy Formation and the uppermost Quaternary sediments. In the frame of this study, the Karataş volcanics, which were formed as a result of the second magmatic activity of the Eocene period, are studied in detail. The Karataş volcanics are greenish black on their undisturbed clean surfaces, and some parts are brown-purple in color and have distinctive crack systems. It shows a reddish-pinkish color distribution in regions where degradation is observed intensely. The SiO2 content, which is the main criterion for determining the magma character of Karataş volcanics, is between 52.09 % and 58.45 %. MgO contents of similar importance are between 0.53 % and 2.21 %. Some of the light rare earth elements, La have 22.2-40.7 ppm, Ce 44.4-67.3 ppm, Pr 5.23-8.88 ppm, Sm 4.41-7.15 ppm, Eu 1.24-1.83 ppm; one of the heavy rare earth elements, Lu have 0.20-0.45 ppm and Yb 1.88-2.98 ppm values. The Karataş volcanics consist of basaltic-trachyandesite and trachyandesite. Evidence of liquid-crystal fractional crystallization (FC) in the phenocryst phase during the formation of the Karataş volcanics is clearly observed in the geochemical diagrams. Traces of partial melting and crustal contamination were found in geochemical studies. Following the closure of the Neo-Tethys ocean in the region, a widespread crustal thickening occurred in the region with the northward divergence of the northern branch of Neo-Tethys, and a suture zone was formed along this line. The Karataş volcanics were formed as a product of active volcanism after the collision in the region.

Geochemical signatures could be used to reconstruct paleoenvironmental controls on paleosols and terrestrial sediments of the Ovalibağ locality in the Çiftlik Basin. In this article,the distribution of the chemical(major and trace elements) and mineralogical composition concentrations. This study helps us to understand the source area, weathering mechanism, abundance, concentration provenance and the economic concentrations of minerals whether hydrothermal or surficial (Low temperature geochemistry), provenance, tectonic settings, reservoir characteristics and in this case, climate variations and how they are distributed. As a result of geochemical measurement, each profile shows a unique change, such as the increase- decrease in the vertical distribution of main and trace element contents. In the same profiles, as molecular weathering index values such as ∑bases/Al, clayeynes, salinization, calcification, provenance, redox conditions, weathering (CIA-K), leaching, immobilization and precipitation were calculated, the outcome helps us to understand how these terrestrial sediments were formed.The thickness, color and material differences between the different sedimentary levels in the region reveals that regional changes have an effect on the formation of sedimentation and erosion, while the amount of fogging or Fe movement also shows that there are climate changes.
