KELSKY VOLCANIC AREA (THE SOUTHERENOSETIYA REPUBLIC): GEOCHEMICAL FEATURES OF ROCKS AND ITS GEODYNAMIC INTERPRETATION

Abstract

At the south-western part of the eastern segment of the Big Caucasus meganticlinorium the quaternary volcanoes of Kelsky volcanic area are situated. Results of petrography and geochemistry investigation of these volcanic rocks have been done. The results of RFA, ICP MA and INAA were presented and discassed. It was shown firstly, that this volcanic rock having of adakite-similar characteristics and according of geochemical conditions its very close to the volcanites which have been origin in subduction geodynamic conditions. The supposition that geochemical peculiarities of these volcanism should connect with a «sholean» tectonic and with a deformational processes, which are developing on interaction between Black Sea-Lesser Caucasus microcontinent and Big Caucasus, was done.
