ON PT CONDITIONS IN MANTLE MAGMATIC CHAMBERS BENEATH THE ARCTIC AND OTHER OCEANS
The geological and geophysical data that indicates oceanization of Arctic ocean crust were analysed. The investigation of the PT-parameters of magma in the mantle of thisand other oceans is conducted. They are about 25 km and 1150 °C, 55 km and 1200 °C, 90 km and 1300 °C, 145 km and 1500 °C, 215 km and 1700 °C. The results are consistent with the advection-polymorphic hypothesis of deep processes.
Key words: mantle of the oceans, deep processes, magma sources, PT-parameters.
