In two test series, liquid and solid gold-based neutron flux monitor materials were investigated with respect to the effects of neutron absorbers such as chlorine, scattering effects, and the dependence of the enhanced activation caused by the epithermal resonance integral. The liquid monitors were prepared from aqueous solutions of tetraamminegold(III) nitrate and tetrachloroauric(III) acid. T...
The Mazra'eh Shadi is located about 130 km northeast of Tabriz (NW Iran) in the Arasbaran metallogenic belt. The deposit occurs as a series of veins within the Eocene andesites. Mineralization shows epithermal system that controlled by fault distribution. Epithermal textures within the veins include comb, vaggy quartz, cockade, boxworke, plate calcite and breccia. Pyrite is the main ore mineral...
На Большом Кавказе описаны различные месторождения и рудопроявления золотого оруденения, в том числе эпитермального. Однако типизация золото-серебряного эпитермального оруденения с использованием физико-химических условий их формирования на современном уровне не проведена. Целью исследования является получение комплексной геолого-минералогической физико-химической характеристики руд уровне. Объ...
The study area is located in the Varzeghan city and in the province of the East Azerbaijan. Mineralization in the Hizeh –Jan area is gold mineralization type and associated with quartz and quartz - carbonate veins and veinlets, which is occurred in the Eocene volcanic rocks with andesite composition. The most significant alteration in this area, is developing of propylitic, argillic and silic...
Despite the existence of a well-known set forecast and search criteria, only three gold silver epithermal deposits were discovered on territory Amguem-Kanchalan metallogenic zone, which has significant resource potential. The base enterprises developing them is extremely limited. aim study to clarify regional local conditions for localization gold-silver mineralization, forecasting searching pr...
