| contents | A detailed description of the ores of Lake Storsjoen was given by Vogt J. H. L., 1915 who pointed out that the ores may be divided into two principal types; first, iron ore with 2% or less of manganese (ex: Ertemalm), and, second, ores with manganese contents of up to 30% (ex: Korinter). The iron-rich ore sometimes occurs as a conglomerate embedded in manganese-rich ores, clearly demonstrating that two distinctly different precipitates are involved. In the iron-rich ore, a concentric structure is common of which light brown layers of loose, almost dusty material alternate with hard and brittle black layers, the thickness of each being 0.5 mm or less. The analyses presented in this paper seem to demonstrate that the composition of the sedimentary ores of Lake Storsjden could result from fluctuations in the composition of ground waters feeding the lake. |
