Record 2 2005-04-14

English

Subject field(s)
  • Tectonics
DEF

A curved downward-flattening fault, generally concave upward.

OBS

Listric faults may be characterized by normal or reverse separation.

OBS

Current debates about the listric(concave upwards) versus planar geometry of normal faults in extensional terranes are partly due to the lack of reliable depth images from seismic reflection data. A recent example of this controversy has arisen concerning the geometry and nature of the Sevier Desert normal fault in west-central Utah(Von Tish et al., 1985; Anders and Christie-Blick, 1994). The presence of shallow-dipping normal faults is one of the most important criteria for recognizing extensional regimes(e. g., Shelton, 1984). In fact, substantial extension can only be accomplished by initially shallow faults or by faults that rapidly rotate toward shallower dips as extension proceeds(Wernicke and Burchfiel, 1982).

French

Domaine(s)
  • Tectonique
DEF

Faille dont le pendage diminue en profondeur, dessinant une courbe concave vers le haut.

OBS

Les failles listriques semblent dues à l'écartement progressif de deux plaques continentales, ou plus souvent de deux fragments d'une plaque en cours d'étirement. À l'affleurement, elles sont presque verticales, mais en profondeur elles sont quasi horizontales et il semble qu'elles découpent en lames horizontales parallèles la base de la croûte continentale.

Subject field(s)
  • Metal Forming
OBS

drawing: A term used for a variety of forming operations ... The usual drawing process with regard to sheet metal working in a press is a method for producing a cuplike form from a sheet metal disk by holding it firmly between blankholding surfaces to prevent the formation of wrinkles while the punch travel produces the required shape.

OBS

dishing : Forming a shallow concave surface, the area being large compared to the depth.

English

Subject field(s)
  • Equipment and Tools (Water Supply)
  • Wastewater Treatment
CONT

For shallow channels, curved bar screens with bars formed as segments of a circle and installed concave to the direction of the flow are available. The rakes revolve slowly around a horizontal shaft located in the center axis of the curvature of the screen. After passing the top of the bars, the raking plate contacts a metal rocking apron which retains the screenings on the plate until it clears the apron.

Spécialement adapté aux profondeurs d'installation relativement réduites, il a l'avantage de présenter une grande surface utile. Le nettoyage est assuré par un ou deux peignes montés à l'extrémité de bras, tournant autour d'un axe horizontal.
