Forty years later this idea became testable when laboratory apparatus capable of reaching the pressures and temperatures of the upper mantle was constructed and peridotite partial melting experiments were conducted.
WitrynaIn terms of its constituent elements, the mantle is made up of 44.8% oxygen, 21.5% silicon, and 22.8% magnesium. There’s also iron, aluminum, calcium, sodium, and potassium.
