Engadin window

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.

The rocks cropping out in the Engadin window are weakly metamorphosed sediments of middle Jurassic to Eocene age.

[2] They are seen as part of the penninic units similar to the rocks that make up large portions of the Switzerland.

[1] The metamorphic overprint was caused by the closure of the Valais and the Piemont-Liguria during the Paleogene part of the Alpine orogeny.
