In order to micropaleontology, biozonation and age determination of Shurijeh Formation in west part of eastern Kopet Dagh, a stratigraphic section was selected and studied in south of Hamam Ghaleh. Shurijeh Formation with 953 m thickness in Hamam Ghaleh stratigraphic section consists of five lithological units which is different from other identified sections. These lithological units include lower terrigenous-evaporite unit, lower carbonate unit, middle terrigenous-evaporite unit, upper carbonate unit and upper terrigenous unit. A total of 402 samples were examined in this study. Three biozones were determined in studied deposits based on recognized microfossils and their stratigraphic range chart. In this study the Late Kimmeridgian?- Hauterivian age was ascribed to Shurijeh Formation in Hamam Ghaleh stratigraphic section.
