ΜΕΛΕΤΗ ΤΩΝ ΜΟΛΑΣΣΙΚΩΝ ΙΖΗΜΑΤΩΝ ΤΟΥ ΣΧΗΜΑΤΙΣΜΟΥ ΤΣΟΤΥΛΙΟΥ ΤΗΣ ΜΕΣΟΕΛΛΗΝΙΚΗΣ ΑΥΛΑΚΑΣ (ΜΙΚΡΟΠΑΛΑΙΟΝΤΟΛΟΓΙΑ-ΣΤΡΩΜΑΤΟΓΡΑΦΙΑ)

THIS STUDY IS A MICROPALEONTOLOGICAL AND BIOSTRATIGRAPHIC INVESTIGATION FOSSILIFEROUS MOLASSIC DEPOSITS FROM THE MESOHELLENIC TROUGH IN THE GREVENA AREA OF NORTH-WEST MACEDONIA. IT PRESENTS A) A DETAILED DEFINITION OF THE PLANKTONIC FORAMINIFERA AND OTHER MICROFOSSILS FOUND WITHIN THE MOLASSIC SEDIMENTS, B) A BIOZONATION BASED ON THE STRATIGRAPHIC RANGES OF THE PLANKTONIC FORAMINIFERA IDENTIFIED AND C) A MINERAL AND GRAIN -SIZE ANALYSIS OF THE SEDIMENTS DISCUSSED. THE RESULTS HAVE BEEN USED TO DRAW CONCLUSIONS REGARDING THE PALEOGEOGRAPHIC EVOLUTION OF THE STUDIED AREA IN THE EARLY MIOCENE. THE SEDIMENTARY SEQUENCES DISTINGUISHED IN THE AREA OF STUDY ARE: A) THE LOWER AND MIDDLE OLIGOCENE SEDIMENTS OF THE EPTAHORION FORMATION, WHICH CONTAIN A RICH MICROFLORA (ASPROECCLESIA AREA, SECTION A), B) THE UPPER OLIGOCENE SHALLOW MARINE DEPOSITS OF THE PENTALOFON FORMATION, WITH MOLLUSCS (ITEA AREA, SECTIONS I2 AND I3), C) THE LOWER MIOCENE MOLASSIC DEPOSITS OF THE TSOTYLION FORMATION, WHICH IS RICH IN MICROFOSSILS AND COVERS ALMOST THE WHOLE AREA OF STUDY, AND D) THE FLUVIATILE-LACUSTRINE BEDS OFPLEIO-PLEISTOCENE AND HOLOCENE AGE. FROM THE ABOVE ROCKS, ONLY THE LOWER MIOCENE BEDS OF THE TSOTYLION FORMATION HAVE BEEN DISCUSSED IN DETAIL; THIS IS BECAUSE THEY INCLUDE AND ABUDANT AND WELL- PRESERVED FORAMINIFERAL FAUNA AND MICROFLORA.
