Palaeomagnetic research was carried out in the North Caucasus, Azerbaijan, Mountainous Mangyshlak and Central Kopetdag. The ten most complete marine sections of the Lower Cretaceous were selected. They provided opportunity to make reliable references of palaeomagnetic columns to the ammonite zones from the general stratigraphic scale. About 7500 oriented samples were selected from outcrops. The data on the Berriasian-lower Aptian deposits magnetism in the North Caucasus and the Western Central Asia combined with other authors data provide the material for revision of Neocomian palaeomagnetic structure.
