ΣΥΜΒΟΛΗ ΣΤΗ ΓΝΩΣΗ ΤΗΣ ΓΕΩΔΥΝΑΜΙΚΗΣ ΕΞΕΛΙΞΗΣ ΚΑΤΑ ΤΟ ΠΕΡΜΟΤΡΙΑΔΙΚΟ ΣΤΟ ΧΩΡΟ ΤΗΣ ΑΝΑΤΟΛΙΚΗΣ ΕΛΛΑΔΑΣ

DETAILED GEOLOGICAL STUDY OF THE "PALEOZOIC" OF ATALANTI (LOCRIDA, E. GREECE),PTELEOS (E. OTHRYS MT) AND GIALTRA (N. EUBOEA ISL.) TOGETHER WITH OBSERVATIONS FROM OTHER PERMO-TRIASSIC OCCURRENCES OF EASTERN GREECE (THE TERM UNDER THE GEOGRAPHICAL AND GEOLOGICAL MEANING AS WELL) SUCH AS ATTICA, SALAMINA, CENTRALEUBOEA, HYDRA, CHIOS AND VARDOUSSIA MT., POINT OUT THAT DURING PERMOTRIASSIC TIMES THE PASSAGE FROM A PRE-ALPINE OROGENIC SYSTEM TO THE FIRST STAGE OF THE ALPINE SYSTEM IS OBSERVED, WITHOUT ANY KIND OF AN IMPORTANT STRATIGRAPHIC UNCONFORMITY ("TRIASSIC TRANSGRESSION" ACCORDING TO SEVERAL AUTHORS). THE ALPINE PALEOGEOGRAPHIC ORGANIZATION PREVAILS TOTALLY ALL OVER THE AREA OF THE FUTURE HELLENIDES FROM THE LADINIAN/CARNIAN BOUNDARY. THE PRE-ALPINE SITUATION WAS ABSOLUTELY DIFFERENT AND WAS CHARACTERIZED BY VARIOUS PALEOGEODYNAMIC ENVIRONMENTS SUCH AS BASINS WITH FLYSCH- TYPE SEDIMENTATION (CHIOS, SALAMINA, ATTICA, C. EUBOEA), CONTINENTAL SLOPES WITH TURBIDITES, OLISTOSTROMES ETC (KAKI VIGLA OF SALAMINA), CALCAREOUS NERITIC PLATFORMS (PTELEOS, HYDRA, CHIOS), AREAS WHICH REMAIN FOR A LONG PERIOD EMERGED (CHIOS ALLOCHTHON FROM M. PERMIAN TO U. TRIASSIC). THE EXISTENCE OF ALL THESE FACIES TOGETHER WITH THE PRESENCE OF ? EARLY-MIDDLE TRIASSIC VOLCANICS (WHICH PARTLY SHOW CALC- ALKALINE CHARACTERISTICS INDICATING VOLCANIC ARC DUE TO SUBDUCTION PHENOMENA) AND OTHER EVIDENCES (METAMORPHISM, PLUTONISM ETC) POINT OUT THAT THE AREA OF THE FUTURE HELLENIDES WAS DURING PERMO-TRIASSIC INFLUENCED BY AN ACTIVE OROGENY (CIMMERIDES?).
