In this area are present some Mn mineralizations, represented by quartz and quartz-carbonate veins embedded in Diaspri (jasper) formation of Nucleo Metamorfico Apuano. There are also cm-thick layers of braunite and Mn-silicates, concordant with the main schistosity of the rocks (S1).
The importance of this area is due to the significant samples of hollandite and piemontite that are possible to collect here. Besides, scheelite from here represents the second occurrence in the Apuan Alps, after the occurrence cited by Duchi et al. (1993) among the minerals of Calcaferro mine, near Stazzema.
Sugilite and serandite are the second reports for Italy, after Cerchiara mine (Borghetto Vara, La Spezia).
It is possible to distinguish three kinds of occurrences of Mn-minerals:
- Type A: quartz-carbonate veins. In this occurrence there are a lot of species: albite, braunite, clinochlore, hematite, hollandite, muscovite, piemontite, rutile, scheelite, titanite.
- Type B: quartz veinlets. In this type of occurrence it is possible to find only nice braunite crystals and small globular aggregates of todorokite.
- Type C: braunite lenses. Usually the only mineral present is braunite. Rarely, there are also sugilite, serandite and a carbonate of Ca and Ba.
