Differentiation of the Geomorphologic Environmental State in Oaş Mountains. The Eastern Carpathians develop to the Transylvanian Depression a long chain of Neogene volcanic mountains that continues much over the Romania’s bounds. The Oaş Mountains, part of their Northern group, represent a very complex geologic and geomorphologic area, with a polycyclic magmatism, with a large variety of volcanic structures (intrusive bodies, effusive volcanic forms with central eruption, volcanic cupolas, isolated volcanic bodies, plateaus, calderas etc.), high degree of fragmentation and reduced altitude (Piatra Vişcului, 823 m). The geomorphologic environmental states display on a large specter: temporality states (relicts, inherited, actual, of aggradation etc.), critical environmental states (tectono-physical polyphasic, tectono-magmatic, talaso-denudational, morpho-sculptural, critical human-made – physical), of conflict between the geomorphologic system and the external factors (fragility, environmental decline etc.).

Keywords: environmental geomorphology, palimpsestic character, increased sensitivity, induced dysfunctions.
