The Internal zone comprises Cretaceous, Paleogene and Miocene
(pre-Sarmatian) molasses, up to 12-km thick. The Paleozoic basement is
overlain by the Upper Cretaceous (Turonian-Danian) Stryy series of fly-
shoid rhythmically alternating sandstones, siltstones, argillites, marls and
limestones, over 1,000-m thick. The Paleogene sequence includes mas-
sive Paleocene-Lower Eocene sandstones and a sandy-clayey alternation
of the rest of the Eocene. The Oligocene complex (the Menilite series) is
an up to 2,000 m thick alternation of shales, argillites and sandstones. The
lower portion of the Miocene is a thick (up to 800-1,000 m) sequence of
Aquitanian evaporites, variegated Burdigalian rocks (up to 2,500 m) and
Helvetian grey-colored sandy-clayey rocks (up to 3,200 m). The External
zone section begins with variegated Middle Jurassic clastics (up to 500 m).
