The investigation of the PT-parameters of magma in the mantle of this and other oceans is conducted. They are about 25 km and 1150 °С, 55—60 km and 1200 °С, 95 km and 1300 °С, 145 km and 1500 °С, 210 km and 1700 °С. The results are consistent with the advection-polymorphic hypothesis of deep process...
