  • Article title : Investigating the biofacies and lithofacies of Tirgan formation in the eastern section of Kopeh-Dagh
    Article type : Paleontology and Stratigraphy
    Location : 20th symposium on geosciences

    Fulltext :

         Based on this study , eleven stratigraphy sections from
    lower cretaceous sediments in East-North of Iran selected in

    two additional sections,Natu and Derazab.
    Based on lithofacies,about 13 microfacies in this area have been recognized, and based on all of the founa and microfacies, Aptian
    ages were proposed for this formation in these sections.
