Albania offers a classical section across a folded belt.
The Apulian platform (Sazani zone) with its Mesozoic
platform carbonates form the foreland. Proceeding towards
the
east
, the Ionian zone with its basinal Mesozoic-Paleogene
sequence and a thick Neogene foredeep sequence was
deformed during the
Middle
to late Miocene and the
Pliocene. The main decollement level is at the base of the
Upper Triassic evaporites. The Ionian zone is the center of
the oil production of southern Albania. Much of the
production is from structures involving Neogene clastics
with minor production from Mesozoic carbonate reservoirs.
Source beds in the Ionian zone occur in the Triassic, the
Jurassic and the Cretaceous.
Farther
east
, the Kruja zone involves Cretaceous
platform carbonates. Where folded during the
Middle
Oligocene, the Kruja zone is overlain by the complex west-vergent
flysch nappes of the Krasta-Kucali zone. The flysch
nappes extend underneath the great allochthonous lower
Mesozoic ophiolite complexes of the Mirdita zone. The
ophiolites were emplaced during the Upper Cretaceous.
Finally, the Korab zone to the
east
appears also to be
underlying the great Mirdita complex. It consists of Paleozoic
(Silurian-Permian) schists and carbonates, overlain by
Permo-Triassic redbeds and evaporites, and Mesozoic
carbonates. The Korab units may envelope part of the
Mirdita ophiolites.
