Реферат: | eng: This study presents the first fluid inclusion data from quartz of albite-carbonate-quartz altered rocks and metasomatic quartzite hosting gold mineralization in the Pechenga structure of the Pechenga-Imandra-Varzuga greenstone belt. A temperature of 275-370 degrees C, pressure of 1.2-4.5 kbar, and the fluid composition of gold-bearing fluid are estimated by microthermometry, Raman spectroscopy, and LA-ICP-MS of individual fluid inclusions, as well as by bulk chemical analyses of fluid inclusions. In particular, the Au and Ag concentrations have been determined in fluid inclusions. It is shown that albite-carbonate-quartz altered rocks and metasomatic quartzite interacted with fluids of similar chemical composition but under different physicochemical conditions. It is concluded that the gold-bearing fluid in the Pechenga structure is similar to that of orogenic gold deposits.
