|Name:||Named in 1985 by Donald Ralph Peacor, Pete J. Dunn, William B. Simmons, and Fred John Wicks after its composition, containing CAlcium, sodium (Latin = NAtrium), and PHophorus.|
The mineral consists of tiny colorless needles (to about 100 +/- microns) completely covering pieces of stilbite. The type material came from mineral collector, Sid Steris, who on being told of its being named a new mineral revealed that he had cleaned the lot is a mild phosphoric acid solution and who believed the efflorescence of needles were just a result of chemical cleaning of the stilbite.
