The tracts range from about 50,000 to 130,000 km² in area. The Urals host 8 known porphyry copper deposits with total identified resources of about 6.4 million metric tons of copper, at least 20 ...

2014-1-5 · The Urals are well known for their volcanic-hosted base-metal massive sulfide (VHMS) and orogenic lode gold (mesothermal) deposits (Koroteev et al., 1997, Herrington et al., 2005, and references therein).However, there are also relatively little studied porphyry and epithermal systems, besides of a few historically important examples such as the Gumeshevskoe skarn-porphyry deposit (Grabezhev ...

Variations in lead isotopic composition are caused by mixing of mantle and crustal lead sources. The input of radiogenic 206Pb took place during the post-ore phase as a result of a series of tectono-magmatic events, which include emplacement of at least two phases of the Chelyabinsk pluton.
