Аннотация: The results of studying geochemistry of phemophilous group in near-ore apogneiss and aposhale metasomatites of the Kedrovskoye mesothermal deposit in the North Tranbaikalia are presented. According to mineralogy-petrochemical data it was defined that metasomatic haloes belong to beresite metasomatic formation with propylite-like profile of transformations at the area periphery. Silica loss up to the half of its mass from the back zones was stated in the initial ores and conditions of this loss were determined. Silica removed from the ores served as a basis for formation of gold-bearing quartz veins. In the back zones of near-ore metasomatic haloes contrast anomalies of phosphorous, titanium, magnesium, manganese, iron, potassium and calcium were found. Femic orientation of gold-bearing metasomatites demonstrates the generation of metal-bearing fluids in mantle magmatic chambers.
