Abstract

For the first time, the presence of bismuth, rare for the north of the Urals, was found in the gravelstone of the Lower Ordovician Obeiz Formation in the Subpolar Urals. Bismuth is represented by small rounded grains (about 1 µm) that form chains in bornite. It has been suggested that its source could be greisenized rocks at the contacts of the parent rocks of the Parnuk complex and granites of the Salner-Mankhambov complex.
