Conrad discontinuity

Conrad discontinuity

A region, at depths of 17 to 20 km under some parts of the continents, in which the speed of seismic P waves increases abruptly from about 6. 2 km/s to about 6. 6 km/s. Unlike the deeper, Mohorovicic discontinuity, the Conrad discontinuity seems to be absent over large regions. It may mark the contact of granitic and basaltic layers.
