Geo-environmental research of submarine sediments of Northern Cyclades
Summary:
The aim of the present study is to determine the origin of the sediment samples and to relate it with the environment dynamics and the geological background of the islands that define the study area. The practical part of this thesis took place in the laboratorial sections of the Hellenic Centre for Marine Research (H.C.M.R), at the laboratories of the Department of Geology and Geoenvironment of the National and Kapodistrian University of Athens and the laboratories of the Department of Chemical Engineering of the National Technical University of Athens. The sampling of the sediments was carried out byHellenic Center for Marine Research (H.C.M.R.) from 1986 to 1987.In the present study were conducted sedimentological, mineralogical and chemical analyzes in 75 samples of sediments, derived from the marine area of North Cyclades.Sample analyzes were carried out to determine the particle size distribution of the samples, mineralogical analyzes using XRD-SEM methods and the use of stereoscopy, for the determination of minerals and fossils, and XRF analyzes to determine the main and trace elements. Furthermore, the percentage of the carbonate portion of the sediments, under examination, was determined. The evaluation of these results led to the creation of a comprehensive guide, which includes mineralogical tables, geochemists maps and maps highlighting the particle size distribution of sediments in the sea area of the Cyclades, which is bordered by the islands of Tinos, Mykonos, Paros, Naxos and Syros.Finally, the direct connection of the material with the geology of the area and the increased carbon content in the samples with the existence of carbonate bio-communities, which are favored by the low depth and good oxygenation of the area, should be noted.
