ABSTRACT

The drilling and investigation of the Kola superdeep borehole SG-3 for the first time provided direct data on the structure and composition of the ancient continental crust at previously inaccessible depths. Rock density and their anisotropy in elastic properties were used as the main parameters for the formalized description of the borehole SG-3 section and the reference profile on the day surface. The first parameter reflects the rocks’ lithology, the second accounts for the intensity of synmetamorphic tectonic deformations. The obtained petrophysical parameters of metamorphic rocks: density, porosity and the volume anisotropy coefficient KAVp, allowed to give the petrophysical and geophysical correlation of seismic zones and faults along the Kola superdeep borehole section and on the surface of the Pechenga ore district.

Keywords: petrophysical properties, Kola superdeep borehole, fault zones, waveguide.
