FEMOPHILIC ELEMENTS IN WALLROCK METASOMATITES AND IN ORES OF MESOTHERMAL GOLD DEPOSITS − NEWSLETTER OF MANTLE DEEP

There were found contrast anomalies of femophilic element association: P, Ti, Mg, Mn, Fe, Ca-in back zones of zonal wallrock metasomatite haloes of mesothermal gold deposits in Eastern Siberia (Russia), formed in crystal sole (Irokidinsk, Kedrovsk) and in Proterozoic strats of black silstones (Kedrovsk, Chertovo Koryto), in the nearest (up to 1,5 km) margin of geosutures. Metasomatites in back zones are folded with crystalline silica, sericite, carbonate rock impured with pyrite and represent products of potassic- sulphuric- carbon-dioxide metasomatism with input of recomposed sulphur, carbon dioxide into rocks by disproportionation of alkali with almost complete eduction of Na ant partially of silicon. Femophilic elements grade in metasomatites grows in hundreds …some in hundreds % comparatively to original rocks, but decrease to Clark when removing from solution leading geosutures. The joint with solution femophilic elements are fixed in leucoxene, rutile (Ti), carbonate rock (Ca, Mg, Fe, Mn), apatite (P). Taking into consideration other factors – alternate input of mild alkaline mafic melt and metal-bearing solutions, closeness of isotopic ratio of carbonate oxidated carbon to meteorite standard it was concluded about generation of metal-bearing solutions in deep focus of mafic melt.
