Transpression (original) (raw)
Транспрессия — , сочетающий условия сдвига и сжатия. Зоны транспрессии образуются в случае, если сдвиговая зона испытывает дополнительное боковое сжатие. Показателями зон транспрессии являются взбросо-сдвиги и так называемые структуры цветка (структуры пальмового дерева), представляющие собой пакеты тектонических пластин выдавленных из зоны сдвига.

| dbo:abstract | In geology, transpression is a type of strike-slip deformation that deviates from simple shear because of a simultaneous component of shortening perpendicular to the fault plane. This movement ends up resulting in oblique shear. It is generally very unlikely that a deforming body will experience "pure" shortening or "pure" strike-slip. The relative amounts of shortening and strike-slip can be expressed in the convergence angle alpha which ranges from zero (ideal strike-slip) to 90 degrees (ideal convergence). During shortening, unless material is lost, transpression produces vertical thickening in the crust. Transpression that occurs on a regional scale along plate boundaries is characterized by oblique convergence. More locally, transpression occurs within restraining bends in strike-slip fault zones. (en) La transpressione in geologia è un tipo di deformazione da scorrimento che si discosta da un semplice taglio a causa di una componente simultanea di compressione perpendicolare al piano di faglia. Questo movimento causa alla fine un taglio obliquo. In generale è molto improbabile che un corpo che si deforma subisca una compressione "pura" o uno "scorrimento orizzontale" puro. Le quantità relative di compressione e di scivolamento possono essere espresse dall'angolo di convergenza alfa che va da zero (scorrimento orizzontale ideale) a 90 gradi (convergenza ideale). Durante la compressione, a meno che non si perda materiale, la transpressione produce un ispessimento verticale nella crosta. La transpressione che si verifica su scala regionale lungo i bordi delle placche è caratterizzata dalla convergenza obliqua. Più localmente, la transpressione si verifica all'interno di piegature di contenimento in zone di faglie a scorrimento orizzontale. (it) Транспрессия — , сочетающий условия сдвига и сжатия.
