1.1.2. Distribution of Flysch Sediments
Flysch sediments form one of the most characteristic geogenerations in the Mediterranean
Lower Cretaceous. Their distribution coincides with the basic arcs in
the Mediterranean Region: the Gibraltar, Alpine and Carpathian-Balkan arcs
from the north, and the Calabro-Sicilian and Dinaric-Aegcan from the south, which
indicates the great role of the tectonic control (Durand D e 1 g a, 1980).
The flysch is also developed in two characteristic lineaments: Pyrenean and of
the Kraistides, as well as in the Caucasian geosynclines.
The flysch sediments in the Mediterranean Region began to be formed at the
end of the Jurassic as a result of the change taking place in the geodynamic situation
between the two plates: African and Eurasian.
Here we shall examine briefly the Upper Jurassic-Lower Cretaceous flysch
as a unified geogeneration in the following sequence, applied by Durand De 1ga
(1980) and slighty expanded here: (1) Carpathian flysch, starting with its best
studied sections in Poland and proceeding westward to the Perialpine flysch, then
eastward (Romanian Carpathians and the Fore-Balkan): (2) Caucasian flysch;
(3) Dinaric flysch in the Bosnia-Beotian trough and the adjacent zones; (4) Apennine
