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 example, complete, doubly terminated. Not just a good fluoro-richterite, it is a choice example of an amphibole. Its inclined terminations show textbook monoclinic symmetry. Note there is one small indentation on one termination, which is not distracting.

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