“…The first forearc sediment fill is represented by the Maastrichtian-Lower Palaeocene Aktaştepe Formation comprising conglomerates and sandstones at the base, which Clark and Robertson (2005) interpret as fluvio-marine, although their organic geochemistry shows them to be terrestrial (Sonel et al 2008), just like the equivalent sedimentary rocks around the Tuz Gölü Basin. These rocks pass upwards into fine-grained calcarenites, micrites and sandstone-mudstone intercalations with rare conglomerate horizons.…”

“…The surrounding basins (especially Tuz Gölü-Eregli-Ulukışla and Ç ankırı-Ç orum basins) have been investigated in detail for their petroleum properties related to Tertiary succession. Middle Eocene marine units are considered to have marginal potential as source rocks surrounding a basin as in the Tuz Gölü basin (Ayyıldız, 2006;Sonel et al, 2008) and some wells produced noneconomic gas. Therefore, marine Eocene clastics could be a candidate for source rock in the Kozaklı basin; however, there have not been any details published on the stratigraphic succession or hydrocarbon exploration in the study area (Özdemir and Ayyıldız, 2014).…”

The authors present the hydrocarbon source rock potential and reservoir properties of the Eocene Formations in the Central Anatolian Kozaklı Basin. Potential source and reservoir rocks in the Kozaklı basin include transgressive-regressive bank carbonates, fore-bank, deep-marine shales and sandstones, and coal and bituminous facies. The organic geochemical data of the Middle Eocene shales (Sarılar Formation) show that inadequate to marginal source rock qualities, and marginally mature to overmature characteristics, resulting from heat flow regime of the studied area. Alemli Member of theİncik Formation is good to excellent according to TOC wt% and immature to mature source rock from T max values. Sedimentological features and age data indicate that the Uzunlu Formation was deposited under the control of antecedent topography. Reservoir properties of the Uzunlu Formation and Keklicek member indicate that the carbonate unit is not adequate for reservoir rock. However, siliciclastics of the Sarılar Formation could be reservoir potential due to its high porosity and permeability values.

“…The oil and natural gas reserves in Turkey are of minor scale, and solid fossil fuels account for the primary potential as energy sources [18]. Some areas in the above-mentioned regions have been investigated for organic geochemistry [19,20] and only a few studies focused on the inorganic element contents of oil shales [21,22]. However, none of these studies considered major and REE contents.…”

The study area is located in the south of Dağhacılar village of Göynük town in Bolu Province, Turkey. This study is a pioneering work in Turkey on the genesis and environmental characteristics of oil shales and other shallow marine-type sedimentary rocks regarding their major and rare earth element contents. The abundances of SiO 2 , Al 2 O 3 , TiO 2 , K 2 O and Fe 2 O 3 decrease in the following order: claystone > oil shale > marl. CaO and MgO abundances are ranked in the decreasing order as follows: marl > oil shale > claystone. These results reveal the presence of two different genetic groups-detrital and marine. The same groups were also established in the correlation studies of elements. TOT/C and TOC contents of rocks observe the following order: oil shale > marl > claystone, and as a result of variations in redox conditions they also vary in a wide range. Total carbon and total organic carbon are positively correlated with the group representing clays and negatively correlated with CaO, MgO and MnO. That is why TOT/C and TOC are associated with clays. The positive correlations between some major oxides (e.g. SiO 2 , Al 2 O 3 , Fe 2 O 3 , TiO 2 and K 2 O) and REE might indicate that clays and iron oxy-hydroxyls play an important role in transportation and deposition processes. The only slight negative Ce and positive Eu anomalies and Ce/Ce* and Eu/Eu* values recorded in the depositional environment indicate low oxygenated and anaerobic (reducing) conditions.
