Folded metasandstones surrounded by schists (a type of metamorphic rock) with a pen for scale.
#GeologicalRelief for my American friends...
Some of the best folds I have seen in my life in schists and metasandstones... second phase folds refolding an earlier foliation parallel to bedding.
Paleozoic basement, Bocca di Magra, La Spezia (Italy)
