Summary:Based on the study of rocks in fault zones on the western slope of the southern Urals, it is shown that carbonaceous rocks are confined to the most dislocated parts of the sections and spatially associated with magmatic rocks. They are characterized by specific geochemical features with anomalous contents of gold and platinum group elements (PGE) and native tin mineralization that is atypical of terrigenous rocks. Transformation of these rocks is mainly governed by reduced mantle fluids penetrating into upper levels of the Earth's crust at early stages of tectonomagmatic activation. The subsequent inversion of the fluids in the Earth's crust leads to the formation of carbonaceous rocks with atypical mineralization and high PGE content.[PUBLICATION ABSTRACT]
