An overlapping (postvolcanic) ore mineralization of volcanic rocks building up submarine edifices in the Sea of Japan has been semi-quantitatively and qualitatively evaluated for the first time. The study considers the main types of volcanic rocks (marginal continental, post-rift, and alkali ones) and focuses primarily on mineral phases formed in them by nonferrous, noble, and rare metals. The most enriched are post-rift rocks. That is due to the initial magma’s fluid saturation, as well as long-lived volcanic and postvolcanic processes.
