extensional tectonics definition

& Brownfield, M.E. & Fossen, H. 1998: Early Paleozoic orogenic collapse, tectonic stability, and late Paleozoic continental rifting revealed through thermochronology of K-feldspars, southern Norway. generated in a strike slip system at transpressive and transtensional fault bends. [1] Extensional accretionary orogens form by creation and destruction of large arc/back arc basin systems, generated by extension and sediment infilling during prolonged slab retreat, but episodically thickened by basin inversion during short‐lived (∼10 Ma), orogenic contraction events. Extensional tectonics led to the formation of strongly subsiding basins (e.g., Saint Florent and Aleria basins), which are filled with sediments up to 2 km thick, deposited since the Burdigalian (Ferrandini et al., 1996) and continuous with the offshore Corsica basin.

Zones of thickened crust, such as those formed during continent-continent collision tend to spread laterally; this spreading occurs even when the collisional event is still in progress. tectonics. Soc. 3. In philosophy of language, a context in which a sub-sentential expression e appears is called extensional if and only if e can be replaced by an expression with the same extension and necessarily preserve truth-value.The extension of a term is the set of objects that that term denotes..

Cenozoic geology of the Yerington district, Nevada, and implications for the nature of Basin and Range faulting.

[6] After the collision has finished the zone of thickened crust generally undergoes gravitational collapse, often with the formation of very large extensional faults. An extensional fault is a fault that vertically thins and horizontally extends portions of the Earth's crust and/or lithosphere. Le service web Alexandria est motorisé par Memodata pour faciliter les recherches sur Ebay. Divergent plate boundaries are zones of active extension as the crust newly formed at the mid-ocean ridge system becomes involved in the opening process. The section reproduced convincingly demon- strates that parts of a given hanging wall may remain unrotated while other parts may rotate in opposite direc- tions.

FIG. ○   Anagrammes 1. defining a word by listing the class of entities to which the word correctly applies From Wikipedia, the free encyclopedia. Stretching is generally measured using the parameter , known as the beta factor where , is the initial crustal thickness and is the final crustal thickness.

Extensional faults are generally planar and, so long as the stress field is orthogonal to the Earth's surface initiate with a dip of 60° typically continuing down to the base of the seismogenic layer. Breakaway fault 6.

We conclude from this that (1) the sense of rota- tion in a given hanging wall does not indicate its trans- port direction and (2) the boundaries between tilted … a left-stepping bend on a sinistral fault, a zone of extension is generated. Extensional tectonics is associated with the stretching and thinning of the crust or the lithosphere.This type of tectonics is found at divergent plate boundaries, in continental rifts, during and after a period of continental collision caused by the lateral spreading of the thickened crust formed, at releasing bends in strike-slip faults, in back-arc basins, and on the continental … Les lettres doivent être adjacentes et les mots les plus longs sont les meilleurs.
