My studies of the crustal structure focus on:
  • regional crustal models,
  • processes that control crustal evolution, such as formation of deep basins and crustal roots,
  • mechanisms that control the depth to Moho,
  • and mechanisms of crustal underplating.
1. Regional crustal model for Europe, Greenland, and the North Atlantics region (EUNAseis)
2. Regional crustal model for Siberia (SibCrust)

3. Regional crustal model for southern Africa

  • SibCrust is a new digital crustal model for Moho depth and crustal structure in the
    West Siberian Basin and the Siberian Craton (60-140E, 50N–74N).

  • SibCrust model includes both Vp velocity and thickness of five crustal layers,
    including:
  • the sedimentary cover,
  • the upper crust,
  • the middle crust,
  • the lower crust,
  • the high-Vp lowermost crust,
  •    and the upper mantle Pn velocity.

  • Our compilation is based on digitization of all seismic profiles published since 1960
    and sampled with a nominal interval of 50 km, which provides a dense regional data
    coverage.
  • Data quality has been assessed and quantitatively assigned to each profile based
    on acquisition and interpretation method and completeness of crustal model.
  • The database represents major improvement in coverage and resolution and
    includes depth to Moho, thickness and average P-wave velocity of five crustal
    layers and Pn velocity.
  • Exclusion of non-seismic data allows application of the database to potential field
    modeling.

  • EUNAseis is a new digital crustal model for Moho depth and crustal
    structure in Europe, Greenland, Iceland, Svalbard, European Arctic
    shelf, and the North Atlantic Ocean (72W–62E, 30N–84N).

  • EUNAseis model includes both Vp velocity and thickness of five
    crustal layers, including:
  • the sedimentary cover,
  • the upper crust,
  • the middle crust,
  • the lower crust,
  • the high-Vp lowermost crust,
  •    and the upper mantle Pn velocity.

  • Our compilation is based on digitization of original seismic profiles
    and Receiver Functions from ca. 650 publications which provides a
    dense regional data coverage.
  • Exclusion of non-seismic data allows application of the database to
    potential field modeling.
