The western Peloponnese, being very close to the Hellenic Trench, is one of the most active areas in Greece. The study area is located at the central western part of Peloponnese and it is developed in a NNW-SSE direction along 45 km, parallel to the Ionian Trench, which occurs at a distance of only 30-40 km to the west. Based on the morphotectonic studies of the neotectonic macrostructures of the central-western Peloponnese in many scales, it was concluded that the main neotectonic mega-structure is the "Megalopolis-Lykaeon-Minthi-Tetrazio Composite Morphotectonic Structure" (MELYMITE CMS) (1st order structure). The neotectonic deformation is expressed not only by faults, but also by folds which in some cases are the principal structures of the neotectonic deformation. Neotectonic folds occur in the Alpine formations as well as in the post-Alpine ones in various scales. The folds, and the ductile deformation in general, are not easily observed on the surface because of the intense presence of brittle tectonics. A rotational couple stress-fi eld could satisfactory incorporate and explain the brittle-ductile neotectonic structures of the area. © 2008 E. Schweizerbart'sche Verlagsbuchhandlung. |
