Özet
Based on the technological progress, the improvements of the software packages and multi-electrode measuring systems have enabled to perform the Electrical Resistivity Tomography (ERT) measurements more widely, faster and more reliable in various disciplines of earth sciences. Herein, some recent case study examples performed by ERT technique for uncommon-purposes such as investigation of coastal environs are presented. Imaging the lower parts of the beach and dune sands (or other covering units) of layered coastal deposits, which were cemented with calcium carbonate after the development by the control of wave, current and wind, and also the buried geological structures and fossil topographies covered by those beach and dune sands, shows significant contribution of ERT technique on the investigations of coastal geology and paleogeography. Thus some case studies, which have been performed in Black Sea (Sile, Karaburun, Kiyikoy) and Aegean Sea (Bozcaada Island) coasts, and their findings were presented here. The depositional characteristics, subsurface geometry and contact relations of those fossil coastal deposits cemented on different geological periods from Late Pleistocene to Late Holocene provide noteworthy contributions in understanding regarding sea level changes, paleo-wind and current dynamics. The derived-ERT images obtained from the field studies yielded key information about the depositional nature of the deeper parts of the studied layers.
