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 other way to separate the earth descriptively is into a outer layer of rigid rock called the lithosphere that ends at a depth of 100km and another layer of more plastic rock called the asthenosphere that goes to a depth of at least ... WebTo say that the lithosphere floats on top of the asthenosphere suggests a degree of easy buoyancy that isn't quite right. A second order control on trench depth is the age of the lithosphere at the time of subduction. The subduction process consumes older oceanic lithosphere, so oceanic crust is seldom more than 200 million years old.
