Popis:	Orthorhombic barium thiosulfate monohydrate, triclinic barium thiosulfate fluoride, triclinic barium sulfite and monoclinic hydrated barium aluminium trisulfide hydroxide have been isolated and identified as natural weathering products in old smelting mill slags. None of them have been found in nature before, but two of them are known as laboratory products. They represent a stepwise sequence in sulfur oxidation numbers and are potential intermediates in the familiar but little-understood oxidation of sulfides to sulfates and thus throw light on the mechanism of the natural oxidation of sulfide ores. The nature of these phases and co-existing species suggests formation between about Eh -0.45 v at pH 11 and Eh -0.6 v at pH 13.[▭
