New observations on Permian stratigraphy in Greece and geodynamic implication

New detailed stratigraphic and micropaleontological works on the famous exposures of Permian rocks in Hydra rich in Foraminifera, allows to define the stratigraphy of other outcrops in Aegina, Salamis, Attica and Chios. A synthetic section is presented which is characterized by the development of 3 successive carbonate platforms during the Permian and by 4 main tectonostratigraphic events. The youngest of these events marks the closure of the Paleotethyan ocean and the collision of a former Gondwanian/Cimmerian passive margin in the S with an active margin in the N.
