THE KARST IN ANO VLASSIA ACHAIA (GREECE) AND THE CONTRIBUTION OF OLONOS -PINDOS GEOTECTONIC UNIT ON ITS FORMATION
Résumé
The study area includes the Selinous river hydrologie basin on East Erimanthos (Olonos) Mountain, to close to Ano Vlassia village (N. Péloponnèse - Greece). It is formed at an altitude between 700 - 2.169 m and occ 'Dies an area 30 Km2. It belongs to the Olonos - Pindos geotectonic unit, which characterized by lithostratigraphic unevenness, intense folds, successive thrusts with NE - SW directions and transverse faults. Lithostratigraphic and tectonic conditions are accountable for a directed karst development with many karstic basic planes. The above research includes systematic survey in all karstic formations that were observed. Karrens, kluft karrens, shallow dolines and dry karst valleys are developed on the surface. Furthermore, an underground formation was found and composed by caves, gulfs and an underground karstic river. Above 25 karstic fountainheads were observed which gush from the limestones with a 100 m3/h (summer) maximum supply. The imperfect development of surface karst, the good development of underground karst, karstic fountainheads, hydnlogical network and vert, allow for the studied area to be classified to the Transitional type of karst Dy Cvijic (1926) or to Halbkarst by Grund (1903).
