About BassaniteHide

Francesco Bassani
CaSO4 · 0.5H2O
Vitreous, Dull, Earthy
Specific Gravity:
2.69 - 2.76
Crystal System:
Named in 1910 by Ferruccio Zambonini in honor of Professor Francesco Bassani [October 29, 1853 Thiene, Italia – April 26, 1916 Capri, Italia], Professor of paleontology, University of Naples, Italy.
May occur as pseudomorphs after gypsum.
Very similar to omongwaite; structurally related to chinleite-(Y).

Apparently a common precursor phase of anhydrite and gypsum (Van Driessche et al. 2012; Ossorio et al. 2014).

Classification of BassaniteHide

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

7 : SULFATES (selenates, tellurates, chromates, molybdates, wolframates)
C : Sulfates (selenates, etc.) without additional anions, with H2O
D : With only large cations

6 : AXO4·xH2O

25 : Sulphates
4 : Sulphates of Ca, Sr and Ba
