WebMay 28, 2024 · BRITTLE FAULTING. Because most rocks are brittle at low temperature and low confining (lithostatic) pressure, virtually every rock at or near the Earth’s surface exhibits evidence of brittle failure, i. deformation-induced loss of cohesion. Brittle failure results from the irreversible and very rapid propagation and connection of cracks, a ... WebScarps related to strike-slip faulting generally form because the fault moves an area of higher topography up against a lower area. When such a scarp blocks off a drainage, it is called a shutter ridge .Where two topographic lows are moved next to each other, they form a tectonic furrow.
