oa Inner structure and kinematic of the Mankivska fault zone

New geophysical, geochemical and petrological data of the linear geological structure of fault-dyke nature have been considered in the crystalline basement of the western part of the Pobuzhsky Mining District of the Ukrainian Shield. This structure is expressed in a magnetic field as linear anomaly with intensity greater than 1000 nTl up to 1.5 km in width, with scale 1:50 000. Stretching of the structure (north-south 69 °) is perpendicular to the general latitudinal and northwestern direction of the geological formations of the study region. The northwestern flank of this band of the maximum magnetic anomaly for more than 40 km is accompanied by an expressed linear minimum, which corresponds to the axial part of the Mankivska fault zone. This tectonic lineament has until recently had no analogues agree geophysical features, tectonophysical measurement, extent and direction in the western part of the Ukrainian Shield.
