TECTONIC AND RECENT MOVEMENT CLUES IN THE PRE OREAK

Inside the Pre Oreak Cave were found morphologies due to the recent tectonic activity. The geological conditions, the morphologic evidences as well as the entities of the movement measured in correspondence to karst morphologies found near the fault planes are, therefore, of great interest. Upon the observations so far concluded, recent movements with dislocations between some millimetres and about 1.5 centimetres were found. Upon the examined data, the particular and current tectonic activity is underlined and the exceptional dislocation of terragenous quaternary dislocation is confirmed. The morphologies underlined and the objective gathered data, therefore appear, as a whole, fundamental for understanding the evolution of the karst systems and, at the same time, for studying the regional recent and current seismic-tectonic evolution.
