Gypsum is the dominant mineral in the evaporite-bearing Pliocene deposits of the Çankiri Basin. In claystones, the abundance of smectite, dolomite, illite/mica and chlorite in association with minor amounts of mixed-layer chlorite-smectite, mica-vermiculite, amphibole, serpentine, quartz and feldspar together indicate an alkaline environment. Minor kaolinite is also present in some clay samples. Smectite is both detrital and authigenic. Palynological analysis revealed the existence of a mixed forest (Pinus, Cathaya, Tsuga, Cedrus, Abies, Quercus, Ulmus, Juglans, Pterocarya, Acer, Carya, Carpinus, Fagus) dominated by Pinus with a widespread herbaceous understory (Poaceae) interspersed sparsely with open areas occupied by Asteraceae. This flora reflects warm-temperate and humid climatic condition. ?13C analyses have shown that the vegetation was dominated by C3 plants. © 2017 The Mineralogical Society.eninfo:eu-repo/semantics/closedAccessCentral AnatoliaMixed-Layer ClaysPalaeoclimatePalaeoenvironmentPollenSmectiteTurkeyÇankiri Basin?13C AnalysisArticle52335136310.1180/claymin.2017.052.3.06Q2N/A
