Ultramafic rocks of the Karabash Massif (South Urals): mineralogy, geochemistry, metamorphism

The paper is devoted to the mineralogical and geochemical composition of the Karabash ultramafic Massif and geochronological stages of its formation. The identification of such minerals as garnet, high­aluminum chromespinelides, and amphiboles evidences the multistage formation of the massif. The concentration of petrogenic, rare and rare earth elements indicates that ultramafic rocks have both mantle features and evidences of their transformation in the crustal environment.
Keywords: ultramafic rocks, Karabash Massif, minerals, geochemistry.
