In geology, a rift is a linear zone where the lithosphere is being pulled apart and is an example of extensional tectonics. Typical rift features are a central linear downfaulted depression, called a graben, or more commonly a half-graben with normal faulting and rift-flank uplifts mainly on one side. Where … See more Most rifts consist of a series of separate segments that together form the linear zone characteristic of rifts. The individual rift segments have a dominantly half-graben geometry, controlled by a single basin-bounding … See more Many rifts are the sites of at least minor magmatic activity, particularly in the early stages of rifting. Alkali basalts and bimodal volcanism are … See more • The Asunción Rift in Eastern Paraguay • The Canadian Arctic Rift System in northern North America • The East African Rift See more • Geology portal • Rift zone • Wilson Cycle See more Rift initiation The formation of rift basins and strain localization reflects rift maturity. At the onset of rifting, the upper part of the lithosphere starts to extend on a series of initially unconnected normal faults, leading to the development … See more The sedimentary rocks associated with continental rifts host important deposits of both minerals and hydrocarbons.

Taupō Fault Belt - Wikipedia

Webtectonic basins and rift valleys, landforms characterized by relatively steep, mountainous sides and flat floors. The steep sides are created by displacement on faults such that the valley floor moves down relative to the surrounding margins, or, conversely, the margins move up relative to the floor.
