“…Yet, according to the ∑1( n -C 10 – n -C 22 )/∑2( n -C 23 – n -C 35 ) ratio, long-chain n -alkanes are dominant except for the samples numbered ES342 and ES338. While CPI values (1.83–3.53) support terrestrial higher plants’ input, they are characteristic of immature organic matter. ,,− OEP values (1.29–2.63) also produce the same result as CPI values (Table ). High UCM is observed due to the low maturity of samples in the gas chromatogram.…”

“…This is a typical characteristic in coal samples, especially in those that have low maturity. 80 The Pr and Ph concentrations of isoprenoids are parameters which show the redox conditions of the depositional environment, as well as organic matter type and the salinity of the environment. 75,79,81−84 The Pr/Ph ratio in examined samples varies between 0.82 and 6.29.…”

The organic geochemical characteristics of Soma-Eynez coals located in the southwest section of the Soma Neogene Basin in Turkey were examined, and the depositional environment and maturity levels were evaluated. The analyzed samples were drilling samples taken from the Lower Coal Seam (KM2) to represent the basin. The coal’s total organic carbon (TOC) content is 28.45–73.38%, potential yield (PY) value is 22.43–168.29, and extractable organic matter (EOM) yield is 1204–29774 ppm, which are all indicators that the source rock has excellent hydrocarbon-production potential. T max values are between 389 and 430 °C, indicating an immature stage for hydrocarbon production. This is further supported by biomarker maturity parameters (a high odd-to-even predominance index (OEP), low 20S/(20S + 20R) sterane ratio, low ββ/(ββ + αα) sterane ratio, low 22S/(22S + 22R)(C32) homohopane ratio, and low C29Ts/C29Ts + C29H ratio). Unresolved complex mixtures (UCMs) observed in gas chromatograms point to immature–low mature nonbiodegraded organic matter. The saturated biomarker fractions of KM2 coals are characterized by a high Tm/Ts (C27 17α-trisnorhopane/C27 18α-trisnorhopane) ratio, high Pr/Ph ratio, dominant C29 regular sterane presence, and high C30*/C29Ts ratio. All biomarker parameters showed that terrestrial higher plant materials and algal/bacterial source organisms collectively deposited in the paleo-swamp and under suboxic–oxic conditions.

“…In many basins of the world -the Gippsland Basin of Australia (Shanmugam, 1985), the Mahakam Delta of Indonesia (Huc et al, 1986;Peters et al, 2000), and the Turfan Basin of China (Huang et al, 1991;Sun et al, 2000) the hydrocarbon (oil and gas) potential of coals has been studied; accordingly, studies continue at present in various places (Kotarba et al, 2002;Stasiuk et al, 2006;Davis et al, 2007;Adedosu et al, 2010;Yalçın Erik and Sancar, 2010;Adedosu et al, 2011).…”
