Block view of a rift formed of three segments, showing the location of the accommodation zones between them at changes in fault location or polarity (dip direction) Gulf of Suez Rift showing main extensional faults. In geology, a rift is a linear zone where the lithosphere is being pulled apart [1] [2] and is an example of extensional tectonics ...
A rift valley near Quilotoa, Ecuador. The Ottawa-Bonnechere Graben Þingvallavatn. A rift valley is a linear shaped lowland between several highlands or mountain ranges produced by the action of a geologic rift. Rifts are formed as a result of the pulling apart of the lithosphere due to extensional tectonics. The linear depression may ...
The Midcontinent Rift System (MRS) or Keweenawan Rift is a 2,000 km (1,200 mi) long geological rift in the center of the North American continent and south-central part of the North American plate. It formed when the continent's core, the North American craton , began to split apart during the Mesoproterozoic era of the Precambrian , about 1.1 ...
A map of East Africa showing some of the historically active volcanoes (as red triangles) and the Afar Triangle (shaded at the center), which is a so-called triple junction (or triple point) where three plates are pulling away from one another: the Arabian plate and two parts of the African plate—the Nubian and Somali—splitting along the East African Rift Zone Main rift faults, plates ...
A rift zone is a feature of some volcanoes, especially shield volcanoes, in which a set of linear cracks (or rifts) develops in a volcanic edifice, typically forming into two or three well-defined regions along the flanks of the vent. [1]
Bottom: half graben, more common Block view of a rift formed of three segments, showing the location of the accommodation zones between them at changes in fault location or polarity (dip direction) A rift is a region where the lithosphere extends as two parts of the Earth's crust pull apart.
The formation of the Red Sea – Gulf of Suez rift system was caused by the anticlockwise rotation of the Arabian plate with respect to the African plate. [1] This model is consistent with near orthogonal rifting along the entire length of the rift system.
The West and Central Africa Rift System formed from the Early Cretaceous separation of Africa and South America. [3] This rifting almost tore apart the African continent but instead formed a complex system of extensional, wrench and pull-apart basins.
