Levinsonite-(Y)
Levinsonite-(Y) is a rare mineral from the mineral class of "organic compounds". The mineral was named in honor of Alfred A. Levinson (1927-2005), professor of mineralogy at the University of Calgary, in part because of his origination of the internationally used nomenclature for rare-earth minerals, the Levinson modifier[1], which is a standard in mineralogical nomenclature and allows for the more precise identification and classification of rare-earth minerals.[2]
The type material for Levinsonite-(Y) is kept at the University of Michigan, and the Smithsonian National Museum of Natural History in Washington, D.C.[3]
Discovery
In 1981, T. Dennis Coskren and Robert J. Lauf began investigating a large number of unusual minerals at the Alum Cave Bluff (ACB), Great Smoky Mountains National Park, Tennessee, USA.[2][4] Coskren and Lauf discovered three new rare-earth element minerals, which have subsequently been named coskrenite-(Ce), levinsonite-(Y), and zugshunstite-(Ce). After submission to the International Mineralogical Association (IMA), the naming of Levinsonite-(Y) was approved by the Commission on New Minerals and Mineral Names and given the IMA number 1996-057.[5]
