Abstract: | A precise 3D model of the crust is necessary to start any tectonic or geodynamic interpretation. It is also essential for
seismic interpretations of structures lying below as well as for correct analysis of shallow structures using reflection seismics.
During the last decades, a number of wide-angle refraction experiments were performed on the territory of central and eastern
Europe (POLONAISE’97, CELEBRATION 2000, SUDETES 2003), resulting in many high quality 2D models. It is an interesting and
complicated transition zone between Precambrian and Palaeozoic Platforms. This paper presents 3D model of the velocity distribution
in the crust and upper mantle interpolated from 2D models of the structure along 33 profiles. The obtained model extends to
a depth of 50 km and accurately describes the main features of the crustal structures of Poland and surrounding areas. Different
interpolation techniques (Kriging, linear) are compared to assure maximum precision. The final model with estimated uncertainty
is an interesting reference of the area for other studies. |
