Graben - Wikipedia
WEBA graben is a valley with a distinct escarpment on each side caused by the displacement of a block of land downward. Graben often occur side by side with horsts . Horst and graben structures indicate tensional forces and crustal stretching.
Horst and graben | Faulting, Tectonics & Geomorphology
WEBHorst and graben, elongate fault blocks of the Earth’s crust that have been raised and lowered, respectively, relative to their surrounding areas as a direct effect of faulting. Horsts and grabens may range in size from blocks a few centimetres wide to tens of kilometres wide; the vertical movement.

Horst and Graben - U.S. National Park Service
WEBApr 22, 2020 · Horst and Graben (valley and range) refers to a type of topography created when the earth's crust is pulled apart. This process, called extension, can stretch the crust up to 100% of its original size. As the crust is strained in this way, normal faults develop and blocks of the crust drop down to form grabens, or valleys.
