Figure 10. Schematic map of the Late Devonian volcanic rocks of the Pripyat rift zone [Aisberg et al., 2001].
(1) The area of Late Frasnian-Famennian volcanic rocks in the Pripyat Trough; (2) explosion pipes found by drilling (after N. V. Veretennikov, V. P. Korzun, E. A. Nikitin et al.); (3) subvolcanic bodies proved by seismic data (after S. V. Klushin et al.); the faults bounding: (4) the Pripyat Trough, (5) the Pripyat and Dnieper grabens, (6) the steps of the Pripyat Trough; (7) other faults; (8) seismic profiles. The inset map shows the areas of Frasnian alkaline ultrabasic igneous rocks in the Pripyat-Dnieper aulacogen (PDA) (after [Lyashkevich, 1987] with our additions): (9) PDA marginal crustal faults, (10) zones of old pre-Late Proterozoic transverse crustal faults (figures in circles): (1) Odessa, (2) Znamenka-Piryatin, (3) Krivoi Rog, (4) Kalmius-Aldar); (11) areas of alkaline ultrabasic rocks. The tectonic elements shown in the inset map are (VA) Voronezh anticlise, (US) Ukrainian Shield. The Pripyat-Donetsk aulacogen includes: (I) Pripyat Trough, (II) Dnieper-Donetsk Trough, and (III) Donetsk Foldbelt.
