Abstract The Cretaceous geodynamic and paleogeographic evolution of the northeastern Asian continental margin is summarized in five maps for time‐intervals of 115‐110, 100‐90, 90‐85, 85‐74 and 70‐50 Ma. Four major evolutionary stages are recognized: (i) the moderate extensional tectonic regime and origination of a system of island arcs in the Jurassic‐Neocomian stage; (ii) Middle Cretaceous strong collisional and accretional processes resulting in the Asian continent formation in the Barremian‐Early Albian stage; (iii) the origination of the subduction‐related Okhotsk‐Chukotka continental marginal volcanic belt in relation to the newly formed convergent plate boundary in the Late Albian‐Senonian stage; and (iv) the next collision accompanied by the extinction of the subduction‐related volcanism in the Late Cretaceous‐Early Paleocene stage (Laramian orogeny) and displayed rift‐related processes with the intraplate‐type volcanism on the Asian continental margin. Those stages had been established through the whole Pacific ring and had close genetic relationships with mid‐ocean ridges tectonic activity.
