Geophysical anomalies over epithermal systems
Journal of Geochemical Exploration, 1990Abstract The interpretation of most physical anomalies in epithermal systems needs to be integrated with available geological and geochemical data, and incorporated into a conceptual model of the original hydrology of the system. These anomalies result from the passage of hydrothermal fluids through rocks.

In Europe and Middle East, Turkey is currently positioned as the largest producer of gold with a 2015 production of 27.5 t from predominantly porphyry and epithermal deposits. Although exploration for gold by advanced geochemical methods started in 1980s, Turkey entered into hard-rock mining based on cyanide process for extracting gold from low-grade ...

Characterisation of the TAPIRO BNCT epithermal facility
Radiation Protection Dosimetry, 2004A collimated epithermal beam for boron neutron capture therapy (BNCT) research has been designed and built at the TAPIRO fast research reactor. A complete experimental characterisation of the radiation field in the irradiation chamber has been performed, to verify agreement with IAEA requirements.

Non-volcanic epithermal deposits
1996Abstract Stibnite, stibnite-gold, and stibnite-gold-scheelite mineralization is confined to the Sundaland continental cratonic core area of SE Asia. This gold association .is distinctly different from the gold-silver-telluride association of the Cainozoic volcanic arcs.

Characterization of an epithermal irradiation facility
Journal of Radioanalytical and Nuclear Chemistry Articles, 1987An epithermal energy neutron irradiation facility has been used to perform instrumental activation analysis for iodine, silicon, nickel, zirconium, uranium and thorium. The facility, which is adjacent to the fuel of the University of Virginia 2.0 MW pool reactor, consists of a dry sample region surrounded by a fixed cadmium shield.

Accelerator based epithermal neutron source
Physics of Particles and Nuclei, 2015We review the current status of the development of accelerator sources of epithermal neutrons for boron neutron capture therapy (BNCT), a promising method of malignant tumor treatment. Particular attention is given to the source of epithermal neutrons on the basis of a new type of charged particle accelerator: tandem accelerator with vacuum insulation ...

The Kuranakh epithermal gold deposit, East Russia
2005The Kuranakh mine is one of the largest lode gold mines in Russia and has produced 7.1 million ounces of gold. Through 1997, the mine has extracted 74.1 million tonnes of ore grading 3.57 g/t gold (Benevolskiy 1985). The Kuranakh gold deposit is located within the Central Aldan Ore District on the Aldan shield, on the southern flank of the Siberian ...

Epithermal Positron Effects in Surface Measurements
1987Positrons annihilating at a molybdenum surface have been studied with a beam apparatus. A new extended method of analysis has been employed to model the annihilation spectra as function of incident positron energy. The results indicate that epithermal emission can be accounted for by elastic scattering of positrons near the surface.
