Folds in Biancone-type limestones of the Krasta-Cukali Zone (northern Albania).
Folded Upper Jurassic to Cretaceous Limestones and radiolarites (red) of the Krasta-Cukali Zone north of Komani reservoir (northern Albania).
Cleavage refraction in rocks of the Durmitor Flysch Unit (Montenegro).
Ptygmatic folds in a quartzitic layer within carbonatic host rock. Note that shortening in the fold hinges is accommodated by small brittle faults. Krasta-Cukali Zone, northern Albania.
Pencil cleavage in a marly flysch of the Krasta-Cukali Zone (northern Albania). Such pencil cleavage typically developes close to fold hinges where the layering and cleavage include high angles and form the elongated planes of the rock fragments.
Tight to isoclinal folds in marble (near Osina, Rhodopes, S Bulgaria).

Polyphase deformation in Ordovician schist (near Bosilegrad, SE Serbia). The first penetrative cleavage (subvertical) and a second, sporadic one (subhorizontal) are affected by folding with axial plane traces trending from bottom left to top right.
