WebA common configuration that results from tension forces is the formation of parallel horsts and grabens. As the rock mass pulls apart, it fractures along a series of fault planes where blocks of rock sink downward by gravity, producing long, linear valleys (grabens) and mountain ranges (horsts). WebJun 8, 2024 · Grabens, horsts, and half-grabens are blocks of crust or rock bounded by normal faults (see Chapter 2 ). Grabens drop down relative to adjacent blocks and create valleys. Horsts rise up relative to adjacent down-dropped blocks and become areas of higher topography.
