Abstract

The present study investigates the formation and development of a coastal barrier associated with the recent evolution of the beach/dune system of the Kyparissiakos Gulf (SE Ionian Sea, central Mediterranean Sea) during the late phase of the Holocene (Flandrian) transgression. The study is based on the application of combined geophysical (ERT: Electrical Resistivity Tomography; GPR: Ground Penetrating Radar) and geotechnical (CPT: Cone Penetration Test; boreholes) techniques, supported by sedimentological (granulometric, mineralogical, palaeontological) analyses. According to the interpretation of the collected and processed data, the formation of the coastal barrier started during the transition between the fast and slow phase of the sea level rise (i.e. 6-7 ka BP), which coincides with an increased fluvial sediment inflow induced by the prevailing wetter climatic conditions (8000 - 3700 BP). The development of the coastal barrier most likely involves a progradational beach, associated with the formation of dunes that follow aggradational phases of coastal barrier and beach evolution. Based on ¹⁴C dating, the formation of the two younger dune ridges took place no earlier than 350 and 950 cal yr BP, respectively.

期刊介绍： Physics and Chemistry of the Earth is an international interdisciplinary journal for the rapid publication of collections of refereed communications in separate thematic issues, either stemming from scientific meetings, or, especially compiled for the occasion. There is no restriction on the length of articles published in the journal. Physics and Chemistry of the Earth incorporates the separate Parts A, B and C which existed until the end of 2001. Please note: the Editors are unable to consider submissions that are not invited or linked to a thematic issue. Please do not submit unsolicited papers. The journal covers the following subject areas: -Solid Earth and Geodesy: (geology, geochemistry, tectonophysics, seismology, volcanology, palaeomagnetism and rock magnetism, electromagnetism and potential fields, marine and environmental geosciences as well as geodesy). -Hydrology, Oceans and Atmosphere: (hydrology and water resources research, engineering and management, oceanography and oceanic chemistry, shelf, sea, lake and river sciences, meteorology and atmospheric sciences incl. chemistry as well as climatology and glaciology). -Solar-Terrestrial and Planetary Science: (solar, heliospheric and solar-planetary sciences, geology, geophysics and atmospheric sciences of planets, satellites and small bodies as well as cosmochemistry and exobiology).
