The magmatic rocks of the Shatsky Rise form two groups of rocks replacing one another in time. The earlier ferrotholeiites enriched in potassium compose large massifs. Trachybasalts form seamounts and neotectonic-ridges. The composition of the volcanites indicates that two sources of magmatism took part in their formation: a depleted source characteristic of the basalts of mid-ocean ridges and a "plume" source participating in the formation of oceanic plateaus.
