Rift - Wikipedia, the free encyclopedia

In geology, a rift is a place where the Earth's crust and lithosphere are being pulled apart and is an example of extensional tectonics. Typical rift features are a central linear downdropped fault ...

A rift valley is a linear-shaped lowland between highlands or mountain ranges created by the action of a geologic rift or fault. This action is manifest as crustal extension, a spreading apart of th...

Continental rifting is the poorly understood thermomechanical process by which continents break up and new ocean basins form. Two dominant styles of continental rifting are recognized1. Crevice style rifts are characterized by initial graben formation, local uplift of the graben shoulders, and little or no volcanism.

It explains the Site 900 MORB gabbro as material underplated beneath thinned continental crust or as an aborted point-of-initiation of seafloor spreading, and the alkaline to transitional characters of igneous clasts in Site 897 and 899 deposits as evidence of continental rifting.

Nonetheless, differences in the magnitude of seafloor spreading are systematically compensated by differences in the magnitude of continental extension, which was calculated by reconstructing thinned continental crust to its pre-rifting thickness.

Cretaceous continental rifting that led to separation of Africa and South America was associated with mantle plume activity (Tristian plume) and bimodal volcanic-plutonic magmatism in southwestern Africa and Atlantic margin in South America.
