The Sardona Nappe is a Lower Helvetic tectonic nappe emplaced in an early phase onto the future Helvetic domain, subsequently truncated by the Glarus Thrust and simultaneously cut by out-of-sequence thrusts. It is composed mainly of Late Cretaceous to Paleogene sediments of Ultrahelvetic affinity, cropping out in the area between Linthal and Sargans.
