Figure 12. The distribution of lower Famennian volcanic rocks in the Pripyat rift zone
[Aisberg et al., 2001].
(1) central-type volcanoes: Vetkhin (9), Nadva (10), Gomel (11), East Borshchevskii (12);
(2) fissure volcanoes: Aleksandrov (2), Sharpilov (13), West-Vetkhinskii (14), Yastrebovskii (15), Loev (16);
(3)`contour lines of the total thicknesses of the Elets volcanic rocks, m; (4) predominant composition of the
volcanic rocks: (a) ultrabasic, (b) basic, (c) intermediate; (5) area of Zadonsk volcanic rocks: areas of
volcanic rocks in the Dnieper-Donetsk Trough; (6) undifferentiated Upper Devonian rocks (inferred);
(7) Lebedyan-Polessian (Late Famennian) rocks; (8) contour lines of the surface of the Lower Famennian intersalt
rocks, km; (9) boundary marking the absence of intersalt deposits; (10) eastern limit of the Famennian salt-bearing
rocks. See Figure 12 for the rest of the legend.
