LEFT-LATERAL MOTION [3 records]

Record 1 2011-08-10

English

Subject field(s)
  • Geomorphology and Geomorphogeny
DEF

A fault in which the relative displacement occurs horizontally along the fault plane separating adjacent blocks of rock.

CONT

Strike-slip faults involve motion [that] is parallel to the strike of the fault frequently described as "side-by-side" motion. Strike-slip faults are further described as "right-lateral"(dextral) or "left-lateral"(sinistral) depending if the block opposite the viewer moved to the right or left respectively.

OBS

strike-slip fault; transcurrent fault; lateral fault: terms used at Natural Resources Canada - Earth Sciences Sector.

PHR

Strike-slip fault system.

PHR

Transcurrent fault system.

Key term(s)
  • lateral slip fault
  • strike shift fault

French

Domaine(s)
  • Géomorphologie et géomorphogénie
DEF

Faille le long de laquelle le déplacement relatif s’effectue horizontalement le long du plan de faille séparant des blocs de roche adjacents.

CONT

Les failles de décrochement [...] correspondent à des cisaillements en régime coulissant pour lesquelles le rejet est longitudinal et parallèle à la direction du cisaillement.

CONT

Une faille de décrochement est dite dextre ou sénestre. Elle est dextre si, en regardant vers la trace de faille, l’horizon repère du compartiment opposé semble s’être déplacé vers la droite. Elle est sénestre si ce meme horizon repère semble s’être déplacé vers la gauche.

OBS

faille coulissante; faille de coulissage; faille de coulissement; faille à décrochement horizontal; faille de décrochement; faille à rejet horizontal; faille à rejet directionnel; faille latérale : termes en usage à Ressources naturelles Canada - Secteur des sciences de la Terre.

PHR

Système, zone de failles de coulissage.

Record 2 2008-10-20

English

Subject field(s)
  • Tectonics
DEF

Movement on a strike-slip fault in which the block on the opposite side of the fault from the observer moves toward the left.

CONT

Left-lateral motion. On a strike-slip fault, if one stands on one side of the slip facing it, the other side is displaced to the left.

CONT

Sinistral or left lateral movement. Movement is sinistral (left handed) if the block on the other side of the fault moves to the left, or if straddling the fault the left side moves toward the observer.

CONT

Left lateral motion may prove an important element in the pre-Tertiary history of southern British Columbia.

OBS

left-lateral motion; sinistral displacement : terms used at Natural Resources Canada-Earth Sciences Sector.
