An old iron and manganese mine.
The Fianel Fe-Mn deposit is of syn-sedimentary to diagenetic origin, embedded in Triassic marble belonging to the Starlera nappe. It underwent a polyphase Tertiary metamorphism, climaxing under blueschist- to green-schist facies conditions (Nussbaum et al. 1998).

The lenticular ore body (60x60x20 m) of Fianel was exploited for iron until the end of 19th century.
