Abstract

This research checked and controlled four areas regarding to remains of plants fossils in the age of post-Miocene (Plieocen-Pleistocen) in Iran۱:country-region>۱:place>. Zemestanyourt valley (near Azadshahar, Eastern Alborz) is the first area, Varton in northeast of Isfahan۱:city>۱:place>, Niyeh near Natanz and finally Abyaneh near Kashan were checked by this research for the first time. In Zemestanyourt section the fossilized plant is mostly Quercus (Family Fagaceae). At the base of Varton Travertine (a small hill, Qum Formation) leaf, wood and fruit of fig or Ficus (Family Moraceae) can be found. Near Nieh (Natanz area) Reed or Phragmites (Family Poaceae) can be seen at the base of post Miocene to Pleistocene Travertine. In this area Phragmites is associating with? Acer and Salix leaves. Finally in Abyeneh (near Kashan) within cold water Travertine (deposited on ٍEocene to Miocene volcanic rocks), leaves, woods and remains of Salix (Family Salicaceae) associating with Charophytes (Algae) is abundant. Samples collected from Abyaneh, Inchehbron (near Gonbadkavos), Gavekhoni۱:placename> Lake۱:placetype> (near Varzaneh) and south of Soh (northwest of Isfahan۱:city>۱:place>) were washed and picked and have remains of Charophytes. The presence of Charophytes (Algae) in those areas confirmed that, shallow and salty water were dominated after Miocene in above-mentioned areas. The dominancy of post-Miocene flora in Iran۱:country-region>۱:place> revealed that, a humid and warm climate or ecosystem was dominated within or through depositional time of Upper Red Formation.
