OBS

lago proglacial: No se debe confundir glacial (que está en zonas frías) con glaciar (relativo a una masa de hielo acumulada en las zonas de las cordilleras por encima del límite de las nieves perpetuas). Lamentablemente, las fuentes en Internet no reflejan esta diferencia y utilizan equívocamente "glacial".

Record 5 2005-11-02

English

Subject field(s)
  • Geomorphology and Geomorphogeny
  • Glaciology
DEF

A terrace like ridge consisting of stratified sand and gravel formed as a glaciofluvial or glaciolacustrine deposit between a melting glacier or a stagnant ice lobe and a higher valley wall or lateral moraine, and left standing after the disappearance of the ice ...

OBS

A kame terrace terminates a short distance downstream from the terminal moraine; it is commonly pitted with kettles and has an irregular ice-contact slope.

Key term(s)
  • ice contact terrace
  • ice marginal terrace

French

Domaine(s)
  • Géomorphologie et géomorphogénie
  • Glaciologie
CONT

Cette forme de terrain est due aux eaux de fonte d'un glacier, qui accumulent des sédiments entre la glace et le versant d'une vallée. D'un côté, les sédiments s'appuient donc sur un rebord rocheux et, de l'autre, reposent contre la glace. Quand cette dernière fond, l'ensemble du dépôt se borde peu à peu d'un talus plus ou moins raide situé du côté occupé auparavant par la glace. Une telle construction, comprenant une surface relativement plane terminée par un talus en pente forte, se nomme une terrasse. Dans ce cas-ci, étant donné l'origine de contact glaciaire, il s'agit d'une terrasse de kame.

OBS

fluvioglaciaire : Cette graphie, puisée des Rectifications de l'orthographe recommandées par le Conseil supérieur de la langue française, est attestée dans le Petit Robert (2004).

CONT

Patterned Ground Landforms. ... Thermokarst is a general term that refers to the many landforms that develop in response to the melting of ground ice ... Thawing permafrost creates uneven surfaces that primarily consist of subsidence features that collect water such as collapse scar bogs and small thermokarst lakes ... Two cases are presented to demonstrate the development of thermokarst features.

CONT

Thermokarst features are produced by thawing of ground ice when the climate improves or by fires, disturbance of vegetation, erection of heated buildings, etc. in present-day permafrost areas. Localised collapse produces irregular hollows often with small thaw lakes, which progressively increase in size and coalesce to form large lakes(alases). Enlargment of thaw lakes occurs by thermo-erosion of the permafrost on the shores; this leads to slumping and the sediment released is often spread across the lake floor. The thaw-induced slope failures(ground-ice slumps) cause lake marginal cliffs to retreat at rates of 10 m/year or more. Small thaw lakes often form at the intersection of ice wedge polygons, and when these are joined by water in the marginal furrows of the polygons they form "beaded drainage". Thermokarst features cause many engineering(ground stability) problems encountered in permafrost regions.

CONT

Till may also be squeezed into fracture systems or crevasses in the marginal zone of a receding ice sheet and form a criss-cross, irregular pattern of straight ridges that is more or less oblique to the direction of ice flow; some ridges, however, are transverse and some parallel to this direction. Such crevasse fillings have also been termed linear disintegration ridges

Subject field(s)

  • Geomorphology and Geomorphogeny
DEF

A moraine perpendicular to the direction of ice flow, marking the position of old marginal lobes; it consists of a complex network of low, repetitive ridges which are irregularly branched and variable in length and width. The ridges of till give the surface a bumpy, rolling appearance emphasized by the presence of numerous ponds and depressions. A corrugated moraine differs from a Rogen moraine in size and form.

CONT

In the Interior Plains, low relief ground moraine commonly displays short to elongate, irregular-branching transverse ridges that ... impart a corrugated or washboard-like form and pattern to broad areas. ... The term corrugated ground moraine is proposed for these areas of repetitive transverse ridges ...

OBS

The composite pattern of the ridges [is] generally accentuated by the presence of innumerable ponds and sloughs ...

Moraine perpendiculaire à l'écoulement glaciaire, marquant la position d'anciens lobes marginaux; elle est constituée d'un réseau complexe de crêtes basses et répétitives à ramifications irrégulières, de longueur et de largeur variables. Les crêtes formées de till donnent à la surface une apparence bosselée et ondulée, accentuée par la présence de nombreux étangs et dépressions. Une moraine ondulée diffère d'une moraine de Rogen par ses dimensions et sa forme.

CONT

De vastes étendues des Prairies occidentales du Canada font voir une surface basse et onduleuse de crêtes glaciaires répétitives qui donnent à la surface une apparence généralement courbée et ondulée. Une telle moraine de fond ondulée marque clairement la position d'anciens lobes marginaux de l'inlandsis en retrait (...)
