p.264: 3.4.2 The Piano delle Creste sandstone

Named after the Piano delle Creste rifugio in the Val Antabia, this formation is made of sandstone layers of variable thickness, grain size and composition. It often consists of decimeter-thick beds of more or less quartzitic sandstones alternating with more calcareous sandstones (up to 30% calcite, with small amounts of feldspar and mica). Composition and aspect are rather heterogeneous but these sandstones are always well bedded.
