ON ANOMALOUS SEISMIC HORIZONS IN THE BARENTS SEA SEDIMENTARY COVER

Anomalous seismic horizons in lower Middle-Devonian, Permian-Triassic, Jurassic, and Lower Cretaceous units of the section through the Barents Sea sedimentary cover are inferred from the evidence provided by recent common depth-point seismic surveys. The specific features of their distribution, both lateral and within the complexes, are discussed. A conclusion is made and substantiated that the anomalous reflections are related to tabular bodies of trap-like character. The stratigraphic occurrence of the anomalous horizons within the Barents Sea sedimentary cover correlate positively with the temporal cycles of trap extrusion in the adjacent archipelagos and continental areas.
