horst and graben structure
In physical geography and geology, a horst is the raised fault block bounded by normal faults. The raised block is a portion of the Earth's crust that has remained stationary while the land has sunk on either side of it or has been crushed by a mountain range against it. http://tinyurl.com/2u9ta6
A graben is a depressed block of land bordered by parallel faults. Graben is German for ditch. A graben is the result of a block of land being downthrown producing a valley with a distinct scarp on each side. Grabens often occur side-by-side with horsts. Horst and graben structures are indicative of tensional forces and crustal stretching. http://en.wikipedia.org/wiki/Graben
