Ñarbonates in the metasomatines of the Uralian gold deposits are calcite, dolomite-ankerite, magnesite-siderite (rare rhodochrosite). They recognized in the next metasomatites: gumbeites, eisites, berezites-listvenites, argillizites, jasperoides etc. Carbonete’s composition (or carbonate’s paragenesises) and its ferruginous caused by: 1) educt’s composition (or ratio of Ca – Mg – Fe2+ - Mn in it) , 2) pH of processes, 3) size of chemical potential of CO2 in system. The next data have theoretical and practical significance: a) number of carbonate and its ferruginous in metasomatite’s body increase with deep, b) increase of metasomatite’s degree cause replacement of the elements in carbonates in the next order – Ca – Mg – Fe2+.
