Petrochemical features of acid volcanism of the Sablegorsk Complex (Subpolar Urals)

Abstract

The study of the composition of the rock using petrochemical, geochemical and other analytical studies makes it possible to obtain quantitative information about the content of chemical elements, more accurately diagnose the object under study and create an idea of its genesis. Acidic volcanics of the sablegorsk subvolcanic complex (Subpolar Urals) are represented by rhyolites, trachyrhyolites, rhyodacites, trachydacites and dacites with high silicon contents, up to ultra-acidic varieties, from low-alkaline to moderately alkaline calc-alkaline series of rocks. By the nature of their concentration, trace elements have a very similar distribution with inner continent.
