p.519: an approximately 50 m wide fold hinge containing white siliceous marbles,

outcropping at the Alpe Pradurino (Paleozoic or Mesozoic?; Bearth 1956b) [...] It is also possible that the siliceous marbles of Alpe Pradurino represent a relict of Mesozoic sediments marking the boundary of these two tectonic units, as proposed on the geological and tectonic maps of Switzerland, 1: 500'000 of the Federal Office for Water

and Geology (2005).
