A refraction study of the crustal structure in southern Norway

Abstract

Two seismic profiles across southern Norway have yielded a crustal structure with a good correlation between average topographic elevation and crustal thickness. The Mohorovicic discontinuity was deepest at 36 to 38 km beneath the central portion of the mountain range and shallowest at 28 to 30 km beneath the coast-line of western Norway. The depth and structure of the Conrad discontinuity is uncertain. Observed velocities include P_g between 6.0 and 6.3 km/sec, P_b of 6.5 km/sec, and P_n of 8.05 km/sec.
