About HuntiteHide

Walter Frederick Hunt
1 - 2
Specific Gravity:
Crystal System:
Named by George T. Faust in honor of Walter Frederick Hunt [September 6, 1882 - December 19, 1975], professor of mineralogy at the University of Michigan.
Huntite forms compact fibrous chalky masses. It is found in caverns in magnesian rocks.

Classification of HuntiteHide

Approved, 'Grandfathered' (first described prior to 1959)

A : Carbonates without additional anions, without H2O
B : Alkali-earth (and other M2+) carbonates
