The thickness of the crust, the thickness of the basal (intermediate or lower) crustal layer and the average velocity at the top of the mantle ( Pn) have been mapped using all available deep-penetrating seismic-refraction profiles in the conterminous United States and surrounding border areas. These profiles are indexed to their literature data sources. The more significant long wavelength anomalies on the three maps are briefly discussed and analyzed. An attempt to use Bouguer gravity to validate mantle structure was inconclusive. |
