GEOCHEMISTRY AND PETROLOGY ADAKITES OF SAGASKAJA SUITE THE MIDDLE WATERCOURSE RIVER BAIGOL IN MOUNTAIN ALTAI
Data on geochemistry, petrology of volcanogenic adakites of Saganskaja suite of Devonian on river Baigol of Mountain Altai lead. Adakites occurred by andesites and andesi-dacites of volcanogenic nature. High concentration of zirconium, vanadium, chromium, nickel and low contents of Y, Yb, Rb characterized for their. They are treat to metaaluminous differences. Coefficient Mg# is low and vary from 0,17 to 0,4, pointing on low magnesium number of rocks. Generation of rocks related with melting of upper mantle sources (quartz eclogites, amphibolites) and mixing with crust material. Copper-molibdenium-gold porphyries and epithermal gold-silver ore mineralization related with volcanogenic adakites.
