“…The East European Craton is the coherent Precambrian, mainly Archaean and Paleoproterozoic, part of the continental plate and occupies the north-eastern portion of Europe (Bogdanova et al , 2015. Three independent crustal segments: Fennoscandia, Sarmatia and Volgo-Uralia, collided to form the EEC (Bogdanova et al 1996).…”

“…The central station A0 is located about 50 km from the TESZ. The crystalline basement of the EEC is buried beneath a 5-9 km thick cover of sediments, and is interpreted to be the prolongation of the 1.81-1.76 Ga Trans-Scandinavian Igneous Belt (Bogdanova et al 2015 and references therein). The Polish Basin adjoining the part of EEC discussed in this study is filled with Upper Palaeozoic, Meso-and Cenozoic sedimentary 10-12 km sequences, underlain by a sedimentary "pre-Variscan consolidated crust" reaching the depth of 20 km; Moho is located at ca.…”

Seismic P-and S-wave velocities of the lower lithosphere and underlying asthenosphere at the SW margin of the East European Craton in northern Poland were obtained with different seismic techniques: seismic refraction, P-residuals of the first arrivals from teleseismic earthquakes, P-wave receiver function, and inversion of the Rayleigh surface wave dispersion curves, the last two using data collected in the passive seismic experiment "13 BB star". The uniform array consisted of 13 stations deployed in a 120 km in diameter area. Below the depth of 180-220 km a decrease of about 6% of the S-wave velocity is interpreted as a thermal gradient zone corresponding to a lithosphere-asthenosphere transition. The average mantle velocities down to a depth of 300 km beneath the array are relatively high, exceeding values for other Precambrian cratons by 0.1-0.2 km/s, and cannot be modeled by reasonable mantle peridotite compositions in the lithospheric part of the profile. We suggest that significant peridotite anisotropy could explain the misfit between measured and calculated seismic velocities in the lithosphere.

It includes Paleoproterozoic rocks reworked and/or formed in a series of accretionary orogenic events at 1.92-1.79 Ga (Svecofennian orogeny ;Lahtinen et al, 2005), and wide-spread alkali-calcic, granitic to quartzmonzodioritic magmatic rocks (Transscandinavian Igneous Belt, stippled in Figs.…”
