In this study, the maceral composition and depositional environment of the Şarkikaraağaç coal seam were examined in detail. The results show that huminite is the most abundant maceral group in the coal samples, ranging from 25% to 75%. This is followed by liptinite (1–36%) and inertinite (4–15%). Notably high mineral matter content and abundant framboidal pyrite are among the features that stand out. The relatively low and uniform huminite reflectance values across the basin indicate a consistent and homogeneous coalification process. Based on the maceral distribution and ternary diagram evaluations, it is inferred that the coals predominantly formed in shallow, alkaline, and anoxic wetland environments, specifically of limnic to limnotelmatic character. According to the petrographic composition of the Şarkikaraağaç coals, the coal seams were formed mostly under stagnant water conditions, with the dominant plant input being herbaceous and limited contributions from woody plants.
