Epithermal Deposits of Kamchatka, Russia | Geology of Ore Deposits
Abstract The results of studying the epithermal deposits of Kamchatka, one of the most promising gold-mining provinces of the Russian Federation, are generalized. The deposits are divided into acid–sulfate (Ac-Sul) and adularia–sericite (Ad-Ser) types (Heald et al., 1987). The disadvantages of the scheme, which is the most popular in the …

Epithermal mineralization is an important metallogenic criterion for volcanogenic belts of varying ages. We show that epithermal high-sulfidation deposits are shallow formations in volcanogenic belts, with low-sulfidation deposits being formed at the subvolcanic level and the intermediate between the two types being the deepest …
Low Sulphidation Epithermal Gold Deposits
Although they are a product of the same igneous system, low sulfidation epithermals gold deposits are very different from high sulfidation.
