Jouer, Dictionnaire de la langue françaisePrincipales Références. Listric fault 2. Areas of extensional tectonics are typically associated with: Rifts are linear zones of localized crustal extension. Such bends are known as releasing bends or extensional stepovers and often form pull-apart basins or rhombochasms. a left-stepping bend on a sinistral fault, a zone of extension is generated. 2). 1 Deformation styles. Stretching is generally measured using the parameter , known as the beta factor where , is the initial crustal thickness and is the final crustal thickness.

Intraplate extensional tectonics of the Eastern basin‐Range: Inferences on structural style from seismic reflection data, regional tectonics, and thermal‐mechanical models of brittle‐ductile deformation. During the depositional period of SQ5, although the basin had entered a rifting and extensional period, tectonic inversion occurred, resulting in subsiding in the north and uplifting in the south. [2] In individual rift segments one polarity (i.e. 3. Examples of active pull-apart basins include the Dead Sea, formed at a left-stepping offset of the sinstral sense Dead Sea Transform system, and the Sea of Marmara, formed at a right-stepping offset on the dextral sense North Anatolian Fault system.[9].  | Dernières modifications.

Recent Examples on the Web The team only found evidence of extensional features—both ancient and modern—which suggests that a short, violent birth could have given way to an early ocean. Ronald L. … 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. Extensional tectonics is concerned with the structures formed, and the tectonic processes associated with, the stretching of the crust or lithosphere. 1997. Consider a rectangular parallelepiped, a bricklike block of material with mutually perpendicular planar faces, and let the edges of the block be parallel to the 1, 2, and 3 axes. From Wikipedia, the free encyclopedia. Hartz, E.H, Andresen, A., Hodges K.V. définition - Extensional_tectonics. An extensional fault is a fault that vertically thins and horizontally extends portions of the Earth's crust and/or lithosphere. Asymmetrical in form, it lies parallel to the trend of major extensional BASIN uppe PL AT E LOWER PLATE Fig. 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.

This high heat flow often results in moderate temperature (190-230°C) geothermal resources. 3. Breakaway fault 6. 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. Renseignements suite à un email de description de votre projet. & Cooper M.A. dipping towards the ocean) faults are developed with rollover anticlines and related crestal collapse grabens. Extensional fabrics commonly associated with all these core complexes result from reverse flow along an orogenic channel (channel flow) following peak metamorphism beneath a passive roof stretching fault. On some margins, such as the Niger Delta, large counter-regional faults are observed, dipping back towards the continent, forming large grabenal mini-basins with antithetic regional faults.[4]. In terms of plate tectonics … Chaque lettre qui apparaît descend ; il faut placer les lettres de telle manière que des mots se forment (gauche, droit, haut et bas) et que de la place soit libérée. Cenozoic geology of the Yerington district, Nevada, and implications for the nature of Basin and Range faulting. [3] Large displacements may juxtapose syntectonic sediments against metamorphic rocks of the mid to lower crust and such structures are called detachment faults. Extensional tectonics is concerned with the structures formed, and the tectonic processes associated with, the stretching of the crust or lithosphere.

A passive margin built out over a weaker layer , such as an overpressured mudstone or salt, tends to spread laterally under its own weight. 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. scale extensional structures that can be classified as follows: Continental lithosphere Narrow rift systems East African rift system, Rhine Graben, North Sea Wide extensional systems Basin and Range Passive margins Bay of Biscay Oceanic lithosphere Young oceanic basins Gulf of Suez, Read Sea Mid ocean ridges Mid-Atlantic ridge Back-arc basins Philippines . [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. Field evidence for active normal faulting in Tibet. Take the case of Clark Kent, who is secretly Superman. [1], In areas of relatively low crustal stretching, the dominant structures are high to moderate angle normal faults, with associated half grabens and tilted fault blocks.
