Tilted block faulting : ウィキペディア英語版 | Tilted block faulting
Tilted block faulting, also called rotational block faulting, is a mode of structural evolution in extensional tectonic events, a result of tectonic plates stretching apart.〔 When the upper lithospheric crust experiences extensional pressures, the brittle crust fractures, creating detachment faults. These normal faults express themselves on a regional scale; upper crust fractures into tilted fault blocks, and ductile lower crust ascends. This results in uplift, cooling, and exhumation of ductily deformed deeper crust. The large unit of tilted blocks and associated crust can help form an integral part of metamorphic core complexes and can occur on both continental and oceanic crust.〔 ==Origin of term== The term "tilted block faulting" is a literal description of rotational extension on planar faults, which results in a uniform rotation of faults and crust. Often a "domino-style" stacking of the fault blocks occurs, creating the basis of the terminology.
