Fluoro-richterite found 1976

Fluoro-richterite is a silicate mineral, specifically one of the amphibole group (Hawthorne et al., 2012). The root name richterite dates back to Breithaupt (1865), who applied the name to a mineral from Sweden. The name richterite honors Professor Theodor Richter (1824-1898), a German mineralogist who first analyzed the mineral.

Construction of the Essonville rail line in the 1960s unearthed fine crystals of amphibole formed in carbonatite matrix; such material became a mineral classic. While labeled with various species names over the years, these crystals now fall under the current definition of fluoro-richterite. This is a fine doubly terminated crystal, 2.0 × 1.4 cm, in calcite matrix. Not just a good fluoro-richterite, it is a choice example of an amphibole, showing textbook monoclinic symmetry.

From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona. Laskowski self-collected this specimen March 23, 1976.
