Its age is estimated to be from late Pliocene to early Pleistocene. Sporo-pollen assemblage of the plant-bearing calcic sinter is dominanted by angiospermous pollen (91.4%). Arboreal and shrubs pollen occupies 23.2% in the total pollen. Broad-leaf trees' pollen are mainly Salix, Ulmus> Quercus and Betula. Herbaceous pollen occupies 75.4%y in which Artemisia and Chenopodiaceae are abundant and Xerophyte pollens occupy a high percentages. Sporo-pollen analysis data support that the age of the plant-bearing calcic sitner is from middle-late Pliocene to early Pleistocene. In that time Paleovegetation was mainly represented by mountain steppe (Artemisia, Chenopodiaceae....) mixed with deciduous broad- Itaf forest (Salix, Quercus, Ulmus, Berula ...... in a warm and semidry climatic condition. Art annual mean temperature is estimated about 10?13?C. Altitude of the place where plant-bearing calcic sinter grew at that time was probably 1 500-2 000 m. %K plant-bearing calcic sinter %K sporo-pollen %K paleo-environment
