Seismic attributes of basement in Podvodnikov Basin

Abstract

The seismic attributes of the basement in the Podvodnikov Basin (primarily its P-wave velocities (5.9-6.2 km/s), the VP /VS ratio (1.71), the characteristic diffraction features of reflections from the basement) indicate the continental origin of the basin and suggest that its tectonic evolution began at the pre-oceanic stage of geological history of the Arctic.
