The Udokan Cu–Ag deposit in Transbaikalian Russia is one of the largest individual examples of the sediment-hosted stratiform type. Mineralization is hosted by the Udokan Complex, a ~ 12,000-m-thick metasedimentary sequence deposited between ~ 2.2

The pilot study with Re–Os dating of sulfides from Sukhoi Log and Olympiada gold deposits revealed early Paleozoic ages of the auriferous sulfides from the two largest orogenic gold systems in the Neoproterozoic orogens of the Baikalides framing th

For the first time in the Rudny Altai, we propose to distinguish Besshi- and Kuroko-type deposits, previously considered as members of a single massive sulfide-polymetallic group. The ores of the two deposit types differ in mineral composition, with

Paleoproterozoic collisional (internal) and accretionary (external) orogens, additionally constrained by the matches between the Archaean granulite-gneiss and granite-greenstone terranes, are used to reconstruct the Mesoproterozoic supercontinent Col

The Siberian craton was affected by more voluminous plume events during last 1200 Ma than any other craton on the Earth. These events produced many economically important deposits, of which the tectonic setting of diamond deposits and related alkalin
