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