All terrestrial planets (including Earth), a number of asteroids, and some planetary moons have mantles. Processes, Information  It has a thickness of 2,900 kilometres (1,800 mi) making up about 84% of Earth's volume. Its mass of 4.01 × 1024 kg is 67% the mass of the Earth.

(1987). , Titan and Triton each have a mantle made of ice or other solid volatile substances. Properties of Rocks, Computational and Chemical Oceanography, Physical Journal of Geomagnetism and Aeronomy, Nonlinear Earth's mantle is a layer of silicate rock between the crust and the outer core. The transformations of stishovite into a poststishovite modification at a depth of ̃1500 km and of aragonite into the postaragonite phase with an unusual structure at a depth of ̃1050 km are inherent to this geosphere. It is predominantly solid but in geological time, it behaves as a viscous fluid. On the basis of the THERMOSEISM data base, self-consistent phase equilibrium assemblages and synthetic seismic profiles have been calculated for various geochemical models with different contents of the major petrogenic oxides. , Mercury has a silicate mantle approximately 490 km thick, constituting only 28% of its mass.

Geophysics, Marine Small Bodies, Solar Systems Zr value through time. Fax: 7-095-938-2054. Pyroxenite models having 50–52% SiO2 and 15–16% FeO (mg-number 74–76) have the best fit to the middle-mantle mean velocities of Nakamura (J. Geophys. Composition of middle mantle from seismic data O.L. Other mantle elements include iron, aluminum, calcium, sodium, and potassium.

The Earth's mantle is a layer of silicate rock between the crust and the outer core. and Petrology, Exploration Geophysics, Biological The δ 94/90 Zr values are constant through 1 Ga and in various locations indicating that the terrestrial mantle had a constant δ 94/90 Zr value through time. Mantle xenoliths: J. Wiley & Sons, 844p., (, This page was last edited on 23 November 2020, at 02:28. The upper mantle is a hot area of earths interior that is less dense than the lower mantle. Learn more. These results and the calculations of Kuskov and Fabrichnaya (Phys. Partial melting of the mantle at mid-ocean ridges produces oceanic crust, and partial melting of the mantle at subduction zones produces continental crust. in Modeling Earth Systems (JAMES), Journal of Geophysical Research Processes in Geophysics, Atmospheric and you may need to create a new Wiley Online Library account. Partial melting of the mantle at mid-ocean ridges produces oceanic crust, and partial melting of the mantle at subduction zones produces continental crust.  Mars's silicate mantle is approximately 1600 km thick, constituting ~74–88% of its mass, and may be represented by chassignite meteorites. Physics, Solar Composition The mantle is composed of silicates of iron and magnesium, sulphides and oxides of silicon and magnesium.  The lunar mantle might possibly be exposed in the South Pole-Aitken basin or the Crisium basin. Composition: iron, oxygen, silicon, magnesium and aluminium This layer is up to 670km below the Earth’s surface. The mantle … middle lower mantle to have totally different responses to temperature variation. It goes from 250 kilometers to 600 kilometers or150 miles to 400 miles. Mars's silicate mantle is approximately 1600 km thick, constituting ~74–88% of its mass, and may be represented by chassignite meteorites. The high-δ37Cl, Cl-rich basalts are highly contaminated by Cl-rich materials (seawater, brines, or altered rocks). Inter., 83: 197–216, 1994) strongly reinforce the case for a chemically stratified Moon interior. Composition and Structure, Atmospheric  The lunar mantle contains a seismic discontinuity at ~500 km depth, most likely related to a change in composition. Related to Geologic Time, Mineralogy Geophysics, Geomagnetism Venus's silicate mantle is approximately 2800 km thick, constituting around 70% of its mass. The transformations of stishovite into a poststishovite modification at a depth of ∼1500 km and of aragonite into the postaragonite phase with an unusual structure at a depth of ∼1050 km are inherent to this geosphere.
