  ABSTRACT: Intrusive fluorite-barite-siderite carbonatite of Karasug deposit (Tuva) crystallized from ionic salt melt is dominated by iron chloride with the participation of alkali metal salts. Melt composition and main reaction of mineral formation: NaFeCl3 + 4KF + 2Na2Ca(CO3)2 + Na2Ba(CO3)2 + Na2SO4 = 6FeCO3 + 2CaF2 + BaSO4 + 14NaCl + 4KCl. The highest temperature (550°C - 650°C) brine-melt inclusions in minerals are pseudo-primary. Their predominant Na-K-chloride composition does not correspond to the primary melt, but is close to the residual brine-melt.
