Baltic shield crustal velocity distribution

Robert P. Massé

Open publisher page 5 citations

Abstract

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 P g , 7.17 ± 0.05 km/sec for P * , and 8.13 ± 0.05 km/sec for P n 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.
