Several meters-wide outcrop of the fault zone of the Aga-Vedello Low-Angle Normal Fault (LANF) to the southwest of the Forcellino Pass.

It is nicely preserved and well exposed, thanks to the glacier erosion that smoothed the outcrop surface. The fault zone is characterized by 40–50 cm thick reddish cataclasites, mainly developed at the expense of Early Permian conglomerates in the hanging wall with minor involvement of the footwall paragneisses of the Variscan basement. Cataclasites are partially to completely substituted by tourmalinites. Black tourmalinites represent the strongest effect of tourmalinization; however, there are other, less tourmalinized facies, especially in the basement, in which the replacement by tourmaline commonly follows the main foliation planes, mylonitic bands in strained levels, and discordant fractures.

Tourmalines belong to dravite-schorl series and display a clear zoning with Mg-rich cores and Fe-rich rims.
