Resumo

The receiver function method was used to construct kinematic models of the collision zone of the central part of the East European craton based on data from five broadband seismic stations. A layer of lower velocities with upper boundary at a depth of about 90 km was identified in the upper mantle of the Sarmatia protocraton, marking a mid-lithospheric discontinuity (MLD). The thickness of the identified layer is about 50 km. According to data from stations located in the collision zone, MLD is not detected.
