Name(s) in local language(s):
Miniera di Prabornaz, Saint-Marcel, Valle d'Aosta, Italia
The manganese concentrations of Praborna(z) are restricted to a 4 × 8 m thick quartzite unit of diverse lithologies, which represents the basal part of the sedimentary cover of an ophiolite suite. Together they constituted the Piedmont Nappe which was metamorphosed up to the eclogite facies in Cretaceous times and was retrogressed in the early Tertiary.
The quartzite unit is composed of a succession of siliceous levels characterized by Mn-bearing minerals, reflecting differences in chemical composition and oxygen fugacity inherited from the original sediments. The parageneses evolved during the polyphasic Alpine metamorphism passing through a pre-eclogite blueschist facies event, the main eclogite facies event, and the several post-eclogite stages terminating in the greenschist facies.
These Mn concentrations were subsequently penetrated by various networks of cross-cutting veins and late fractures which were responsible for the mobilization of certain elements, in particular, K, Sr, and Ba.
Note on the mineral list: The reported slavíkite is most probably not from the Praborna mine but from the old Servette-Chuc mining complex in the same municipality.

In my instructional YouTube video tutorial on "Normalizing epidote-group minerals in MS Excel" (https://www.youtube.com/watch?v=IbMLngyz4Cs), the Prabornaz mine "piemontite" analysis I used to illustrate the normalization calculations turned out to be a REE-bearing tweddillite (named as "manganipiemontite-(Sr)" based on the Armbruster et al., 2006 nomenclature).
