Techniques Used in Identification
- Gravity data inversion - Moho depth can be derived by the inversion of satellite gravity data and thereby crustal thickness
- Magnetic stripe data - Most areas of oceanic crust show characteristic stripes due to periodic magnetic reversals during formation at a mid-oceanic ridge. The continental crust is by contrast typically magnetically quiet.
- Seismic refraction and wide-angle reflection data - These data give a precise location for the COB by determining the P-wave velocities along a profile. The two types of crust have distinct P-wave velocities.

Famous quotes containing the word techniques:
“The techniques of opening conversation are universal. I knew long ago and rediscovered that the best way to attract attention, help, and conversation is to be lost. A man who seeing his mother starving to death on a path kicks her in the stomach to clear the way, will cheerfully devote several hours of his time giving wrong directions to a total stranger who claims to be lost.”
—John Steinbeck (1902–1968)
