The Yubileinoe porphyry Au (-Cu) deposit, the south Urals: Geology and alteration controls of mineralization

摘要

based on results of combined petrographical and geochemical mapping of hydrothermally altered rocks of the Yubileinoe Au (-Cu) deposit area, the sequence of hydrothermal activity events have been reconstructed. Such an approach made it possible to determine the geochemistry of alteration zones related both to the mineralized granite porphyry stock and to pre-granitic volcanic and sedimentary units. The results can be used to evaluate the ore potential for alteration haloes associated with hidden granite porphyry stocks within the study area.
