Richterite

Inosilicates

Richterite is a sodium silicate belonging to the amphibole within the structure of the mineral, it is called ferrorichterite; if fluorine, it is called fluororichterite. Richterite crystals are long and prismatic, or prismatic to fibrous aggregate , or rock-bound crystals. Colors of richterite range from brown, grayish-brown, yellow, brownish- to rose-red, or pale to dark green. Richterite occurs in thermally metamorphosed limestones zones. It also occurs as a hydrothermal rocks, and in manganese-rich ore deposits. Localities include Mont-Saint-Hilaire, Quebec and Tory Hill, Ontario and Pajsberg, Sweden; West Kimberley , Western Australia; Sanka, Myanmar; and, in the US, at Iron Hill, Colorado; Leucite Hills, Wyoming; and Libby, Montana. The mineral was named in 1865 for the German mineralogist Hieronymous Theodor Richter (1824–1898).
