More than 1000 deep crustal seismic refraction profiles have been compiled in a standard format which gives the location of the profile, summary of seismic results, topographic and physiographic characteristics, reference to where the full interpretation can be found, and, if available, some information on the gravity anomalies. Several maps are given, showing the depths to the Mohorovicic discontinuity as determined from these profiles.
