Lithosphere thickness depth

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.
