Типохимизм сульфидов Au-Pd-рудопроявления озерное (полярный Урал) in three associations (pyrrhotite-pyrite, pyrrhotite-chalcopyrite-cubanite and bornite
Mineralogy of sandstones and localization of oil matter in productive horizons of high-viscosity oil in permian deposits of the volga-ural region (Russia)-bedded, with inclusions of pyrite crystals. Quartz is predominant in the mineral composition of sand and sandstone, albite
Evolution of parental melts of alkali ultrabasic intrusive massives of Maimecha-Kotui Province (Polar Siberia) that the crystallization of olivine from the high-magnesium pyrite melt occurred in the temperature range of 1510-1260 ° C
(Rare types of tetrahedrite-tennantite ores of a gold ore deposit.These sulphosalts occur as: 1) tiny segregations in sphalerite, galena and pyrite; 2) thin veinlets
A genetic variety and convergence of epithermal gold-silver mineralization-molybdenum-porphyric and pyrite ore assemblies as well as basic-ultrabasic complexes (gold-silver-telluride deposits), and also
The sulfur activity trend inversion in the ore solution and its effect in the gold-quartz deposits formation (example of the Verkhne-Indigirsk district, Yakutia). The drop of the μH2S below equilibrium of burnonite + pyrite = galenite + chalcopyrite results in gold
Ultra dispersed magnetite as a catalyst for aquathermolysis of heavy oil derivative compounds of oxides such as maghemite, pyrite and hematite. Besides the results of SARA
Up-dated ore composition data (Central ore-field, Kuznetsk Alatau) was studied, as well as the distribution of trace elements in pyrite.
Characteristic features of sulphide mineral DTA of pyrite (550-580°) results in destruction of its superficial oxidized film. A thermal change typical
The finding of hydrocarbons migration zones by differential termomagnetic analysis of near surface rocks analysis's curved lines was made. Territory's outline, for which is typical the presence of pyrite
