Abstract
Lignite Beds are fromNeogene formations in Tabriz region. These sediments have deposited in a lake environment. This research introduces plant macrofossils of a marl horizon of this paleo lake in Sari Dagh Altitudes. Charophytes algae and untoothed plant fossils are among fossil samples including: Fraxinus, Salix and Elaeagnus. Charophyte algae and phragmites indicate a freshwater lake with lagoon area near this lake. Salix, Elaeagnus and Fraxinus represent a deciduous forest surrounding the lakeside. The witnesses demonstrate a dry climate and high mean annual temperature during upper Miocene through Lignite Beds precipitation time.
