Klippe
image:thrust system en.jpg|thumb|right|350px|Schematic overview of a thrust system. The shaded material is called a nappe. The erosional hole is called a window or fenster. The klippe is the isolated block of the nappe overlying autochthonous material.
A klippe is a geological feature of thrust fault terrains. The klippe is the remnant portion of a nappe after erosion has removed connecting portions of the nappe. This process results in an outlier of exotic, often nearly horizontally translated strata overlying autochthonous strata.
Examples
- Chief Mountain, Montana
- Mount Yamnuska, Alberta
- The Rock of Gibraltar
- Acropolis of Athens, Greece
- Bac Grillera, Catalonia, Spain. The nappe of which this klippe once formed part had its root in the northern part of the Pyrenees mountain range.
