• Furthermore, this site will provide constraints on mantle source, melting, and magma crystallization processes in the latest stages of basin formation. (iodp.org)
  • In geology , a rift is a linear zone where the Earth's crust and lithosphere are being pulled apart〔( Rift valley: definition and geologic significance ), Giacomo Corti, The Ethiopian Rift Valley〕〔( Decompressional Melting During Extension of Continental Lithosphere ), Jolante van Wijk, MantlePlumes.org〕 and is an example of extensional tectonics . (ne.jp)
  • 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. (ne.jp)
  • The individual rift segments have a dominantly half-graben geometry, controlled by a single basin-bounding fault. (ne.jp)
  • The 600 km-long Main Ethiopian Rift (MER) is a key sector of the East African Rift system connecting the Afar depression to the north, with the Turkana depression and Kenyan Rift to the south 3 . (nature.com)
  • A rift zone is a feature of some volcanoes, especially the shield volcanoes of Hawaii, in which a linear series of fissures in the volcanic edifice allows lava to be erupted from the volcano's flank instead of from its summit. (absoluteastronomy.com)
  • Most rifts consist of a series of separate segments that together form the linear zone characteristic of rifts. (ne.jp)
