Based on the paleogeographic and paleotectonic analysis of sedimentation, the main stages of rising and folding were defined. The department of the North Absheron uplift zone from South-Eastern dipping of the Greater Caucasus taking submeridional direction depression, which has intense dive from the beginning of the Paleogene to the present day is settled. As a result of Prepliocene uplifting and folding within the raising of North Absheron uplift zone and on the crest parts of Darvin Kupesy, Lower Pliocene sediments by angular unconformities bed on the various stratigraphic units of the Paleogene-Miocene complex. Large thickness of sandy and clayey sediments of Productive Series accumulated in a closed, gradually expanding relatively shallow basin, and thin clays of Aghjagil stage deposited in deep water conditions uncompensated by sedimentation. In the Quaternary period quickly upraised Absheron-Pribalkhanian uplift zone and uplifts in North-Western part of the North Absheron zone, complicated by the longitudinal and numerous local faults formed sharp anticlinal zones. Experienced intensive immersion in the Quaternary period Khazri, Gilavar, Novkhany, Ashrafi, Garabagh and other folds located in the South-Eastern part of North Absheron zones turned into buried uplifts.
