Subsequently V.V. Tikhomirov considered the basification of continental crust, with its conversion into oceanic crust as a result of basic metasomatism, that is, the withdrawal of fluids from the mantle to replace and thus oceanize the granitic-metamorphic layer.

Shatskiy (1935) first suggested that large blocks of the continent foundered and have been oceanized where ocean now exists.

Beloussov borrowed the idea, first postulated by the Dutch geologist van Bemmelen, that continental crust could somehow be oceanized, and in the early 1960s he started to make marginal basins by playing with the word oceanization.
