About: Geigerite

An Entity of Type: mineral, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Geigerite is a mineral, a complex hydrous manganese arsenate with formula: Mn5(AsO3OH)2(AsO4)2·10H2O. It forms triclinic pinacoidal, vitreous, colorless to red to brown crystals. It has a Mohs hardness of 3 and a specific gravity of 3.05. It was discovered in Grischun, Switzerland in 1989. It was namedin honor of Thomas Geiger (1886–1976), Wiesendangen, Switzerland, who studied the Falotta manganese ores.
