Abstract

In this paper, we present the spatial distribution of sedimentological and geochemical characteristics of the bottom sediments of Vouliagmeni lake which is located in the SW Perachora peninsula extending into the eastern Gulf of Corinth, Greece. A total of nineteen (19) samples consisting of upper 1-2cm lake bottom sediments were collected and analyzed. Standard sedimentological analyses were carried out including grain size analysis and the measurement of calcium carbonate content (CaCO3), total organic carbon (TOC), total nitrogen (TN) and total phosphorus (TP). Concentrations of major elements and trace elements measured by comparison of X-ray intensities for each element with calibration lines constructed from the analysis of known concentrations in of international standards. The sedimentological evaluation of the Vouliagmeni lake reveal that the high clay content (>30%) in the sediments is apparent in the deep part of the lake. Silt and clay content are >90% in water depths between 23-46 m. The high sand content is found between 3.4 and 8.5 m water depth. The carbonate concentration found between 18% and 64%. Low CaCO3 content is apparent in the deep horizons of the lake. However, TOC, TN and TP are concentrated in the depths with high values found in the sediments between 23-46 m. The high correlation (r>0.83) for Ni, Cu, Pb, Zn and Rb with the Al2O3 shows the same origin of these metals and their association with the detrital materials from the catchment. The elements Fe, Mn, Mg, K, Ti, P and TP are well correlated with the aluminosilicate fraction of the sediments.
