metadata.value: The history of the subsidence of the southern part of the East Barents Sedimentary Basin was
  reconstructed based on the interpretation of 6 seismic profiles along with data from rare deep
  wells. Total and tectonic subsidence were estimated, which made it possible to determine the
  magnitude of the lithosphere stretching factor (β) throughout the history of the region. The
  values of the stretching factor (β) range from 2.5–3.0 for areas with the highest thickness of
  sediments in the central part of the basin, to 1.25–1.66 for areas on the margins of the basin
  with the lowest thickness of sediments. Close values of the stretching factor (β) characterize the
  Atlantic coast of North America in the area with predominant distribution of transitional crust.
  If continental crust from adjacent areas of the Baltic Shield (approximately 40 km) is accepted
  as undeformed, then according to seismic data, the crust thinning was approximately 2.5, which
  is close to thinning estimated from the McKenzie model. Comparison of the obtained data with
  theoretical models of passive margins subsidence indicates that rifting and transition to the stage
  of sedimentary basin formation occurred in accordance with the McKenzie uniform stretching
  model. Although available geological data show that the most intense rifting occurred in the Late
  Devonian, the shape of the total and tectonic subsidence show that the most intense deposition
  occurred in the Permian and Triassic. This contradiction gives evidence for the interpretation
  that after the Late Devonian rifting, a deep-water basin was formed which filled in only in the
  Permian. Water depth estimated from interpretation of sedimentological and paleontological data varies from 1.0 to 3.5 km. According to the shape of the tectonic subsidence curve, during
  the Carboniferous, water depth was close to 3.5 km.
