The contribution of the Passega method and the use of the sedimentological indicators (Folk and Ward), as an evaluation tool of the Holocene depositional environment of Kifissos river, Athens, Greece

Περίληψη

This research concerns the evaluation of the depositional environment in Kifissos river, in N. faliro area (Greece). In order to retrieve the depositional history ten sampling boreholes (P1-P10) are made in the area of Piraeus-N. Faliro in 2005 from the coordination of EFA (Ιcole Francaise d' Athenes), CNRS (Centre National de Recherche Scientifique), SHS (Institut de Sciences Humaines et Sociales) and the director of the ARTEMIS-SHS. Only two boreholes (P2-P4) were selected for further sedimentological analysis as the most representative. After the description of its stratigraphic units, sampling had been followed. Forty samples were collected and they were sedimentologically and granulometrically studied through the laser granulometer Mastersizser 2000 of the Malvern Company. The available obtained data were statistically analysed through the program "Gradistat" to collect the appropriate results for the Passega method and the sedimentological indicators method (Folk and Ward). The results of these sedimentological methods showed that the depositional environment was a combination of a low energy fluvial environment with the contribution of a coastallagoonal environment.
