Paper Abstract

The island of Rhodes represents an uplifted easternmost segment of the Hellenic forearc extending between Greece and Turkey, which is associated with the subduction of the African plate below the Aegean. Middle Miocene-Pleistocene sedimentary basins, are separated by a stack of Alpine nappes of the Hellenide orogen exposed in uplifted fault blocks such as Plattenkalk series (Attaviros Group), Gavrovo-Tripolitza series (Lindos Group), Pindos-Olonos series (Profitis Ilias Group) and several outcrops of Pelagonian series with ophiolitic mélanges. These pre-Neogene formations are dominated by low-grade metamorphic sediments, which were folded and faulted during several phases of the alpine orogeny. The Rhodes region was uplifted in the Middle Miocene after which subsidence and deposition of sediments took place in the Upper Pliocene and Lower Pleistocene. In this paper we present the combined use of remote sensing and GIS techniques for the geological mapping of Rhodes Island at a 1/50.000 scale. The geological formations, geotectonic units and the tectonic structure were recognized in situ and mapped. Interpretation of medium resolution satellite images (Landsat 7 ETM and Terra ASTER) has been carried out in order to detect the linear or not structures of the study area. The in situ mapping was enhanced with data from the digital processing of the satellite data. All the analogical and digital data were imported in a geodata base specially designed for geological data. After the necessary topological control and corrections the data were unified and processed in order to create the final layout at 1/50.000 scale.
