p.418: The Bio' Schists
A small slice of metasedimentary rocks is exposed north of Bio', close to the contact with the Sesia Zone. The Bio' Schists have been interpreted in various ways in the Canavese geological literature. They are composed of a continous sequence of folded pelite, siltite and arenite with interbedded arkose and impure limestone. The Bio' Schists are considered to be Malm in age (Biino & Compagnoni 1989a) such as the Lago Pistono Schists.
