The upper mantle is a thick layer of rock inside the Earth, between the crust and the lower mantle. It has various seismic discontinuities, mineral phases and temperature changes, and affects the movement of tectonic plates and volcanism.
The upper mantle is the layer of silicate rock between the crust and the transition zone, where seismic velocity increases sharply. It is composed mainly of olivine, pyroxene, and garnet, and may contain water and remnants of Theia collision.
30 Απρ 2024 · Learn about the mantle, the mostly solid bulk of Earth's interior that lies between the core and the crust. Explore the upper mantle, the lithosphere, the asthenosphere, and the transition zone, and how they affect tectonic activity and volcanism.
Learn about the upper mantle, the layer of Earth's interior that lies above the core and below the crust. Find out its composition, structure, and features, such as the Mohorovic̆ić discontinuity and the olivine, pyroxene, and perovskite minerals.
1 Ιαν 2021 · Learn about the definition, composition, and properties of the upper mantle, the part of the Earth's interior between the crust and the 660-km discontinuity. Explore the subdivisions, transitions, and features of the upper mantle based on seismic and geochemical data.
A mantle is a layer inside a planetary body bounded by a core and a crust. Learn about the Earth's mantle and other mantles in the solar system, their composition, thickness, and features.
Learn about the upper mantle, the region below the Earth's crust that extends to 410 km depth and consists of peridotite rocks. Explore chapters and articles on subduction zones, mineral physics, and late veneer of the Earth.
