Abstract
The Chorukh-Dairon monzonite-syenite-granite pluton is part of the Chorukh-Dairon volcano-plutonic complex consisting of a number of multiphase plutons and comagmatic volcanic and subvolcanic suites. The rocks of the Chorukh-Dairon pluton affiliate with the shoshonite-latite type generated by deep (mantle) magma; they correspond to the continental marginal variety and were related to chambers generated in metasomatically enriched mantle material. The evolution of the melts during their crystallization differentiation proceeded via the predominant fractionation of, first, mafic and accessory minerals and then feldspars. The drastic decrease in W concentration by minerals that crystallized during the late evolution of the pluton was associated with the enhancement of the emanational differentiation and the development of aureoles of postmagmatic ore-bearing metasomatic rocks.
