Rift basin definition
WebDeep basins are often marked by high pressures and temperatures at depth. Basin analysis is vitally important in oil and gas exploration. It incorporates the processes used to determine where there is a high likelihood of encountering commercial quantities of recoverable hydrocarbons, and thus is integral to prospect generation. WebRift basins have been increasingly the focus of research in tectonics, structural geology, and basin analysis. The reasons for this interest include: (1) Rift basins are found on all passive (Atlantic-type) continental margins …

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 rifts remain above sea level they form a rift valley, which m… WebJan 1, 2014 · Definition. A continental rift (Gregory, 1894; Quennell, 1982, 1985) is a fault-bounded elongate trough under or near which the entire thickness of the lithosphere (see Lithosphere, Continental ; Lithosphere, Mechanical Properties ) has been reduced in extension during its formation.
