Vladimir Vladimirovich Belousov

Died 25 Dec 1990 at age 83 (born 17 Oct 1907). Soviet geologist and geophysicist whose theory of density differentiation (1942) held that movements of the Earth's surface is a result of gradual internal structural changes as denser matter sinks towards the Earth's centre. He visualized continents remaining more or less in place, affected only by vertical motion (though his description of the forces involved was poorly formed.) His position as a prominent scientist was influential in sustaining this concept. Until the late 60's, Soviet scientists delayed accepting newer ideas of plate tectonics. Belousov maintained a belief that vertical movements of continental land masses could not be correctly explained by the plate tectonics theory advanced in the West.«
