Figure 11. Distribution of volcanic rocks in the Eifelian-Frasnian deposits of the Pripyat rifting zone
[Aisberg et al., 2001].
(1) boundaries of the lithofacies zones of volcanic rocks: (I) vent and near-vent rocks,
(II) effusive-explosive rocks, (III) volcanic sediments, (IV) sediments volcanic;
(2) central type volcanoes: Shcherbovskii (1), Aleksandrovskii (2), North-Mikhalkovskii (3), Mikhalkovskii (4), West Mikhalkovskii (5);
(3) fissure-type volcanoes (Borshevskii (6), Mirnyi (7), Vasilievskii (8), Vetkhinskii (9), Nadvinskii (10). The contour lines
show (4) the total thickness of Evlanov-Domanovichi (Late Frasnian) volcanic rocks, m; (5) the total
thicknesses of intrusive rocks in pre-Evlanov Devonian deposits, m; (6) equal amounts of sills in the pre-Evlanov
Devonian rocks, m; (7) western limit of intrusive bodies; (8) area of Frasnian undifferentiated
volcanic rocks in the Dnieper-Donetsk Trough; faults: (9) Northern marginal fault of the Pripyat and
Dnieper-Donetsk Trough; (10) other faults; (11) western boundary of the Bragin-Loev Saddle; (12) structure
contour lines of the synrift rocks (bottom of the Rechitsa-Loev Saddle), km; (13) eastern boundary of salt
interbeds in the late Frasnian rocks.
