Parallel Title:
Landscape history of northern Pieria
Abstract:
Records of fluvial sedimentation, well-dated by absolute and relative means, are used to reconstruct a representative record of Holocene landscape change through time and space in a small portion of northern Pieria. The lower reaches of two small-order streams, the Gerakaris and Agios Dimitrios, are the focus of this study. Less detailed geomorphological investigations in the central part of the coastal plain of Katerini provide an insight into the regional validity of the chronostratigraphic framework constructed for the two streams. Finally, ongoing work in the coastal plain of Korinos offers a general understanding of the Holocene transgressive/regressive record preserved in this portion of the Pierian landscape and a relatively broad integration of inland and coastal records.Eight presently recognised stratigraphic units, comprising at least 8.5 m of alluvial deposits, accumulated in the Holocene Gerakaris valley during the last 8,500 years. Stratigraphic work in the Agios Dimitrios valley focuses on the 6 m thick Holocene alluvial sequence, which embraces seven presently recognised sedimentary units accumulated during the last 7,500 years at least. The sequence preserved in the central part of the coastal plain of Katerini reaches a depth of more than 10 m and embraces alluvial units deposited from before the Early Bronze Age to the present. The Holocene transgressive/regressive record preserved in the coastal plain of Korinos reveals the creation of a marine embayment, most likely during the early Holocene. It also demonstrates the establishment of a sand-barrier and the creation of a lagoon before or during the Bronze Age and the subsequent accumulation of alluvial deposits which progressively pushed the shoreline eastwards and created the modem coastal plain of Korinos.The late Quaternary sequence of northern Pieria is characterised by long periods of landscape stability and pedogenesis, interrupted by infrequent intervals of valley aggradation and occasional stream incision and lateral migration.The geomorphic processes of soil erosion and valley alluviation that altered the landscape of northern Pieria have serious implications for the preservation and visibility of the archaeological record of the area. Sites situated in erosional environments have suffered truncation of deposits, while coastal erosion has resulted in almost total destruction of sites situated on the northern coast of the region. Sediment transported by the streams of northern Pieria, on the other hand, has buried the lower valleys under thick alluvial deposits, obscuring ancient topographies and archaeological sites from surface survey. Finally, local sea level changes and coastal landscape modifications may have exercised a significant influence over settlement location through time. The chance discovery of exceptionally well preserved suballuvial sites, ranging in age from the Palaeolithic to the Byzantine period, underlines the importance and preservation potential of buried archeology in the landscape of northern Pieria.“New” data relating directly to the “ancient topography” of northern Pieria suggest that the battle of Pydna (168 BC) was fought in the Gerakaris valley between the modem villages of Korinos, Nea Chrani and Kato Agios Ioannis.
