seismic refraction

noun [mass noun] Geology

The refraction of elastic waves on passing between formations of rock having different seismic velocities.Gravity and seismic refraction studies have shown that segments tend to have the thickest crust (about 8 km at slow-spreading ridges) at their centres and thin crust at their ends....

Large amounts of seismic refraction and reflection data have greatly improved knowledge of the crustal structure along the outer Voring Basin and the Voring Marginal High.
It extends upwards from a depth of about 6 km, at which depth Precambrian crystalline basement is predicted from seismic refraction studies.
