摘要

A geomorphological study of oceanic "special points"-areas of anomalously active recent volcanism confined to massifs of intraplate volcanic structures-is performed.The distribution of special points over the ocean floor is assessed,and the depths of magmatic chambers and general characteriscs of the volcanites formed are given.The location of spoecial points on major intraplate volcanic structures is analyzed.The spatial and temmporal succession of the topography evolution along the extension of volcanic chains is revealed.The Principal factors of the evolution of volcanic mounds are the suberation conditions of their formation and the gradual isostatic subsidence of the ocean floor.
