Abstract

We present the results of study of mineralogical and geochemical features of black shales from the framing of the Yayusky magmatic complex (Polar Urals). The upper-clark contents of Li, Be, Ba, Ti, Mn, Zr, Rb, Sc, Cs, P, Nb, Ta, Th, and REE were revealed. Rare metal and rare-earth minerals were diagnosed, and the silver min-eral form was found – AsAg2Te (presumably hessite). The metallogenic features of carbonaceous sediments affected by hydrothermal processes in the contact zone with igneous rocks were determined. The conclusion is made about the possible discovery of origin gold in connection with hydrothermal mineralisation the black shale of the region
