Various stratigraphical sections of the Permian rocks in the northwest of Iran (Azerbaijan) shows that this sequence consists of Doroud, Ruteh, and Nesen formations in the southern flanks and Doroud, Surmaq , Julfa and Ali-Bashi formations in Zal and Illanlu sections.
The analysis and study of forminifera assemblages in the carbonate sequence of the area and the comparison of these microfossils with other parts of Iran and neighbouring countries indicate that the age of carbonate units is Kubergandian to Dorashamian in Zal and Illanlu areas and Kubergandian to Djulfian in others sections. Throughout the Azerbaijan, Lower Permian shows a great hiatus.
Field investigation, rock and microfacies studies show many progressive and regressive phases in the Permian sequence of Azerbaijan.
