The zone below the lithosphere

WebThe lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below. The lithosphere is the most rigid of Earth’s layers. WebThe most important result of surface-wave studies is the larger thickness of the lithosphere beneath continents than below oceans (e.g., Gung et al., 2003). At present, the thickness of the lithosphere is considered to vary from a few kilometers at mid-ocean ridges to ∼200 km beneath stable cratons, with 80–100 km being the global average ...

This is … WebThe low-velocity zone (LVZ) occurs close to the boundary between the lithosphere and the asthenosphere in the upper mantle. It is characterized by unusually low seismic shear wave velocity compared to the surrounding depth intervals. This range of depths also corresponds to anomalously high electrical conductivity. WebThe lithosphere is the rigid, outermost shell on Earth. It is composed of the crust and the portion of the upper mantle that behaves elastically on time scales of thousands of years or greater.
