Volcanism and epithermal deposits

Journal of Volcanology and Seismology, 2015
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 deposits.

Epithermal Deposits of Kamchatka, Russia

Geology of Ore Deposits, 2023
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).

Measurements of η for U233, U235 AND Pu239 With epithermal neutrons with epithermal neutrons

Journal of Nuclear Energy (1954), 1957
Abstract The behaviour of η for U 233 , U 235 and Pu 239 has been investigated in the epithermal energy region. For U 233 , η remains constant eneto energies of the order of 100 eV. The value for Pu 239 falls by 12% in passing from a thermal spectrum to a spectrum bounded by 0·15 and 0·5 eV, but remains constant thereafter.

Epithermal positron dynamics

Applied Surface Science, 1997
Energetic positrons implanted into a solid rapidly lose energy, down to the order of an electron volt, through plasmon and single electron scattering. However, the later stages of thermalisation are slower, involving predominantly acoustic phonon scattering, with no discrete boundary between the epithermal and thermal equilibrium states.
