Arsenic minerals in metamorphic rocks of Pre-Polar Urals

In Pre-Polar Urals the metamorphic rocks on the contact of Riphean-Vendian basement and Paleozoic sedimentary cover possess a bright geochemical specification: they are anomalous on Sn, Be, Ge, Zr, TR and As. The long-term study of these rocks revealed a wide complex of accessory minerals - common and exceptionally rare. The given report are generalised our results of study of As-containing minerals.
