About Adranosite
Formula:
(NH4)4NaAl2(SO4)4Cl(OH)2
Colour:
Colorless, white
Lustre:
Vitreous
Specific Gravity:
2.15
Crystal System:
Tetragonal
Name:
After the Greek name of the ancient fire god Adranos (Latin: Adranus) who,according to legend, lived under Mount Etna before being driven out by Hephaestus (Latin: Vulcan). Adranos was worshipped all over Sicily, but particularly in the town of Adranus, now named Adrano.
The Al analogue of Adranosite-(Fe).
Unique combination of elements. One of a few ammonium-sodium sulfates among acmonidesite, adranosite-(Fe), lecontite, möhnite, and therasiasite.
In the crystal structure there are: (1) NaO4Cl2 tetragonal square bipyramids, that have common Cl in corners; (2) AlO6 octahedra and SO4 tetrahedra that join to form spiral chains parallel to [001].
