Abstract
Seismic data recorded as part of the Trans-Scandinavian Deep Seismic Sounding Project were analyzed to determine the crustal compressional velocity distribution of the Baltic Shield. Apparent surface velocities of 6.23 ± 0.05 km/sec for Pg, 7.17 ± 0.05 km/sec for P*, and 8.13 ± 0.05 km/sec for Pn were determined. The crustal compressional velocity distribution of the Baltic Shield was found to be identical to that of the Canadian Shield, indicating a common origin for the crust of both shield regions.
