Thrusting Makes The Bedrock (Geology Orogeny)
- from our Affiliates
Wry suggestive geological humor is alive and well on any of these gifts featuring a schematic overview of an eroded thrust system. The shaded material is the nappe. The erosional hole is called a window or fenster. The klippe is the isolated block of the nappe overlying autochthonous material. These gifts include the educational, scientific saying about orogeny, the process of mountain building via plate tectonics: "Thrusting Makes The Bedrock". Make others do a double-take with a dose of plate tectonic attitude today!
