PALEOCLIMATE OF TABRIZ SEDIMENTS BASED ON PALEO FLORANORTHWEST OF IRAN

摘要

Lignite Beds are from Neogene 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. This demonstrate a dry climate and high mean annual temperature during upper Miocene through Lignite Beds precipitation time.
