Abstract
During the Upper Cretaceous-Lower Tertiary time a continuous (3200 m) sedimentation, mainly consisting of submarine slumps, olistostromes and turbidity currents, was taking place in the western half of the area. Meanwhile, in the eastern half, a granit complex plutonic intrusion was emplaced (Early Paleocene) in a formation, dominantly consisting of basic submarine lavas and tuffites. Uplift, erosion and subsidence of the eroded surface was followed by a marine transgression near the closing of Paleocene times. Following the deposition of neritic and partly littoral sediments (700 m), towards the end of Eocene (post Lutetian) a regression developed over the whole area, causing the deposition of mainly red colored rudite, arenite and lutite, as well as lagoonal white limestone and gypsum.
Horizontal Neogene clastics rest with an angular unconformity on the folded, uplifted and eroded sediments of Late Cretaceous-Early Tertiary age.
