Engadin window
Exposure of penninic rock lying below the austroalpine rocks
The Engadin window or (Lower Engadin window) is a tectonic window that exposes penninic units lying below the austroalpine units in the alpine nappe stack. It has a roughly elliptical shape with the long axis striking northwest-southeast and dimensions of 55 x 17 km.[1]
From a geographic perspective the window stretches from Zernez (Graubünden, Switzerland) to Landeck (Tirol, Austria), or the Lower Engadin.
