Abstract: In this study, economically important the lower and the upper lignite seams of the Somaarea have been examined palynologically. Palynologic determination of 16 different genera and 42species of sporomorphes indicates that the lignite series contain a microflora of Middle Miocene (EarlySerravalian) age.Qualitative and quantitative analyses of this microflora closely match with the EskiMsar pollenassemblages which give an age of Late Burdigalian — Early Serravalian.The spores and pollens of the region define a flora assemblage that indicates a dominance of theMediterranean or slightly more humid and hot climate during the deposition of the coal -bearing formations.
