Abstract
The Late Mesozoic igneous province of East Asia in connection with global geological events is considered. The main structure-forming events and the largest magmatic productivity of the province coincided with the peak of widely manifested plume activity in the Early Cretaceous. A geodynamic model of the magmatic province formation is proposed, relating development of the province with the complex geodynamic setting for the interaction of the convergent boundary with the hot mantle field. The Pacific marginal magmatic belt was formed in front zone of convergence where accretion of terranes occurred with prevalence of supersubduction magma-forming mechanisms. In the western part of the province outside of convergence zone an intraplate volcanic areas were formed due to activity of small mantle plumes.
