About Fluor-schorlHide

Formula:

NaFe²⁺₃Al₆(Si₆O₁₈)(BO₃)₃(OH)₃F

Colour:

Black

Hardness:

Specific Gravity:

3.20

Crystal System:

Trigonal

Member of:

Tourmaline Group

Name:

For the relation to schorl.

Co-Type Localities:

ⓘ Steinberg, Zschorlau, Erzgebirgskreis, Saxony, Germany
ⓘ Le Cave (Grasstein), Franzensfeste (Fortezza), Wipptal (Alta Vall'Isarco), South Tyrol, Trentino-Alto Adige (Trentino-South Tyrol), Italy

The F-analogue of schorl. A complete solid solution exists between the two.

Apparently not really uncommon (Ertl et al., 2016; Kolitsch & Ertl, unpubl. results), confirmed by large analytical dataset in Henry & Dutrow (2011). A correlation between Fe and F content is present (Fe-rich -> F-rich) (Ertl et al., 2016).

First reported, with a full crystal-structure refinement and complete chemical-analytical details, as unnamed F-dominant analogue of schorl from Grasstein, Trentino – South Tyrol, Italy (Ertl et al., 2006).
