The Conrad discontinuity corresponds to the sub-horizontal boundary in the continental crust at which the seismic wave velocity increases in a discontinuous way. This boundary is observed in various continental regions at a depth of 15 to 20 km, but it is not found in oceanic regions. The Conrad discontinuity (named after ...
