【 摘 要 】

To identify petrified tree remains from Upper Pliocene of NE Tabriz, we prepared thin sections from transversal, radial and tangential surfaces, according to specific methods. Whereas possible the slides were examined by optical microscopy. Data related to vessels, rays, parenchyma and other wood elements were determined. Following IAWA list of microscopic features, we made the elementary descriptions and via Inside wood list of fossil woods of Angiosperms, the identification was completed. Results showed that the structure of fossil sample was the same as Angiosperms. Growth ring boundaries indistinct, wood diffuse-porous, ground tissue consists of thin walled fibers, rays abundant, and solitary vessels, were common. The material has been referred to Ash fossil species of Oleaceae at this stage.
