The term "Eulysite" was introduced by A. Erdmann (1848) for rocks containing pyroxene, garnet, and olivine. Palmgren (1917) showed that these rocks basically are the same skarn as the Mn-rich iron ores in the middle of Sweden with two differences: much lower grades of magnetite and higher metamorphic level.
The typical ores of this type mined held 6-12% Mn and 24-33% Fe.
