Shortite
A variety of Minerals
What is Shortite?
Shortite is a sodium-calcium carbonate mineral, with the chemical formula Na2Ca2(CO3)3. It was discovered by J. J. Fahey in well cuttings from the Green River Formation, Sweetwater County, Wyoming, US, and was named to honor Maxwell N. Short (1889–1952), Professor of Mineralogy, University of Arizona. Shortite is associated with commercial trona ores, and some care must be taken when beneficiating crude trona to avoid contamination with shortite.
