p.17: [The Massari Formation] passes upwards to layers of white quartzite, sometimes with garnet, staurolite and kyanite. We name this characteristic intercalation the Val Sabbia Formation. It can be correlated with the thick quartzite of late Early Liassic (Lotharingian) age, so conspicuous in a large part of the Helvetic domain.
