Canaphite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Na2Ca(P2O7) · 4H2O
System:
Monoclinic
Colour:
Colourless
Lustre:
Vitreous
Hardness:
2
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.
