Glarus Thrust and Lochseiten limestone at Piz Atlas. North is left and
south is right. The Lochseiten limestone is the approximately 1 m thick light grey band separating
the greenish Permian Veruccano above from the darkish "Flysch" below.
Foliation in the "Flysch" is dipping south and cut off by the Lochseiten
limestone. Foliation in the Verrucano is flat and parallel to the
Lochseiten limestone. Note yellowish, approximately 25 cm thin, upper layer
of Lochseiten limestone. This is the so called Lochseiten "mylonite", the
actual thrust plane. In the lower part of the Lochseiten limestone the
foliation is parallel to the foliation in the Flysch.
