Grabens and horsts
WebAs the crust extends it fractures in series of fault planes, some blocks sink down due to gravity, creating long linear valleys or basins also known as grabens, while the blocks remaining up or uplifted produce mountains or ranges, also known as horsts. Fault scarps are exposed on the horst block and expose the footwall of the normal fault. WebDec 15, 2024 · Scarps, horsts, and grabens, as well as fault-block mountains, can be formed by this fault because compressional stress is a kind of stress that act of squeezing something. 3. Strike-slip fault: Shear stress. When a hanging wall block rises over its footwall block, the fault occurs
