Özet

This study reveals paleoecological characteristics of the coal-bearing Miocene sediments in the Soma and Usak-Gure basins. Palynological samples from the Soma Basin were obtained from a drilling near Arabacibozkoy. The thickness of drilling is around 425 m. The deposits are mainly made up of fine clastic sediments including lignite and tuffite levels. Levels with clastic and lignite correspond to the Soma Formation. The section containing the volcano-clastic levels corresponds to the Denis Formation. Palynological assemblage from the Soma Formation includes abundant undifferentiated Pinaceae, Cupressaceae, evergreen Quercus, Quercus spp. and Alnus. In the assemblage herbaceous plants, such as Poaceae and Ephedra are observed in low quantities. The Denis Formation also contains a high percentage of sporomorphs recorded in the Soma Formation. Castanea and Engelhardia are also abundant here. However, herbaceous plants recorded in the Soma pollen assemblage with low percentages are represented by both high percentages and varieties and consist of Poaceae, Asteraceae ve Amaranthaceae.
