WebMar 10, 2024 · The transition from continental rifting to oceanic spreading is a crucial yet partly enigmatic stage that determines the birth and further evolution of an oceanic basin. WebDec 23, 2011 · We consider that two mechanisms can induce the structures observed on the margins of the present-day oceanic accretion system. (1) Oblique rifting close to …
Los rifts son fosas tectónicas alargadas donde la corteza terrestre está sufriendo divergencia y distensiones, producto de la separación de placas tectónicas y crecimiento simultáneo de las mismas. El proceso se denomina rifting o, en estadios más avanzados, expansión del fondo oceánico. Si el rift está activo, la tectónica puede producir sismos y vulcanismo recurrente. Los rifts pueden tener … WebIn 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 rifts remain above sea level they form a rift valley, …
