The seismic LAB (i.e. measured using seismological observations) is defined by the observation that there exists seismically fast lithosphere (or a lithospheric lid) above a low-velocity zone (LVZ). Seismic tomographic studies suggests that the LAB is not purely thermal, but rather is affected by partial melt. The cause of the LVZ could be explained by a variety of mechanisms. One way to determin… Web22 nov. 2024 · However, a lithosphere with an initial thickness of ∼80 km would only thicken by ∼13 km due to conductive cooling over the time span of ∼20 m.y.; or, to …
