The palynological
analysis of the early Miocene successions of the Kılçak formation (Central
Anatoia, Turkey) was carried out in order to reconstruct the palaeovegetation.
The pollen spectra indicate a fl ora dominated by Pinus, co-dominance of
Cupressaceae in one of the investigated successions, and lower percentages of
trees such as Taxodioideae within Cupressaceae, Quercus deciduous
type, Carya, Carpinus, Ulmus, Engelhardioideae, Salix, Alnus and
Juglans. Herbs are represented by minor amounts of Poaceae,
Amaranthaceae/Chenopodiaceae and Asteraceae. This flora indicates the presence
of a Taxodium topogenous mire with a nearby riparian vegetation and broadleaved
deciduous mixed forests developed in the surrounding distant mountainous areas.
δ13C analysis shows that the vegetation was dominated by C3 plants. The Kılçak
palynoflora reflects a humid, warm-temperate climate being compatible with the
global warm conditions maintained during the early Miocene
