    Abstract

    In the North Aegean Domain, Thassos Island contains a Plio-Pleistocene basin controlled by a large-scale flat-ramp extensional system with a potential décollement located at depth within a marble unit. Numerous mineralizations associated with normal faults of Plio-Pleistocene age are the sign of fluid circulation during extension. Two main generations of fluid flow are recognized, related to Plio-Pleistocene extension. A first circulation under high-temperature conditions (about 100-200°C) resulted in dolomitization of marbles near the base of the Plio-Pleistocene basin. The dolomites are characterized by low δ
