Sulphohalite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Na6(SO4)2FCl
Colour:
Colourless, gray, greenish yellow; colourless in transmitted light.
Lustre:
Vitreous, Greasy
Hardness:
Crystal System:
Isometric
Name:
The name is derived from its composition, containing SULFur, plus Greek "hals", salt, alluding to its content of halogens. Originally described from the Searles Lake, California, USA by Hidden and MacKintosh (1888).
Sulphohalite Subgroup.

Sulphohalite is an ordered double antiperovskite with the anti-elpasolite structure (Krivovichev 2008).
