Samsari ridge as a youngest volcanic center in lesser Caucasus: A-Ar geochronological and Sr-Nd isotope data

New potentialities of isotope geochronology including K-Ar-method make it possible to describe history of both individual volcanoes and large volcanic areas in period since early to the last stages of their development. Determination of potential volcanic hazard is possible. Investigations of known volcanic centers have been performed. Results of the investigation have led to determination of site of the last volcanism. Numerical time intervals of stages of its magmatic activity have been found. It has been shown that recommencing of volcanic activity is possible in the Caucasus region.
