Record 2 2008-08-25

English

Subject field(s)
  • Petrography
DEF

A marine sedimentary facies characterized by a thick sequence of poorly fossiliferous, thinly bedded, graded deposits composed chiefly of marls and sandy and calcareous shales and muds, rhythmically interbedded with conglomerates, coarse sandstones, and graywackes.

CONT

... there are two major facies of sediments associated with geosynclines or mobile belts. These are the "flysch" and the "molasse" facies.... The flysch facies is marked by its great thickness and its predominantly argillaceous nature. It is almost wholly clastic, although at some stages bedded cherts or radiolarites were deposited.... The bedding is well marked, uniform, and rhythmic... The principal material is shale or silty shale regularly interbedded with graded beds of dark sandstone(usually graywackes) varying from a few centimeters to a meter or two in thickness.... Graded bedding is the rule; large-scale cross-bedding is absent, although ripple bedding may be present.... Noteworthy is the absence of carbonates, except as concretions in siltstone beds.

CONT

The flysch-like facies consists of greywacke-mudstone with locally abundant conglomerate and iron-formation ...

OBS

flysch: term used at Natural Resources Canada - Earth Sciences Sector.

  • flyschlike facies

French

Domaine(s)
  • Pétrographie
DEF

[...] formation de faciès particulier qui peut avoir pris naissance à différentes époques géologiques [et qui] elle est constituée par une alternance [...] de bancs de grès, de sables, de conglomérats, de schistes argileux ou marneux et, plus rarement, de calcaires.

CONT

Des cordillères surgissent, alimentant les bras de mer en matériel de plus en plus grossier. C'est ainsi que le faciès «flysch» s'installe d'abord dans les parties internes, puis vers l'extérieur, ainsi que le montrent les séries orogéniques des diverses unités préalpines et helvétiques dans les Alpes françaises, suisses, bavaroises et autrichiennes.

CONT

Le flysch constitue donc une formation marine essentiellement détritique qui semble s'être déposée, sous l'effet de courants de turbidité, à une profondeur moyenne [...] susceptible de variations dans le temps et dans l'espace.

CONT

Pendant longtemps, le flysch a représenté un dépôt rythmique, très épais [...], très étendu et formé d'une alternance de grès et de schistes ou marnes [...] il y a une prédominance constante de carbonate, dont le taux varie de 30 à 90 p. cent [...] du moins pour les bassins récents [...]

English

Subject field(s)
  • Petrography
DEF

An extensive, postorogenic sedimentary formation representing the totality of the molasse facies resulting from the wearing down of elevated mountain ranges during and immediately succeeding the main paroxysmal(diastrophic) phase of an orogeny...

OBS

A term originally used in Switzerland to describe the soft glauconitic sandstones, marls and conglomerates of Miocene age ... The term is now used to describe all detrital sediments of similar genesis laid down in foredeeps developed during the later stages of a major diastrophism.

OBS

molasse : term used at Natural Resources Canada-Earth Sciences Sector.

French

Domaine(s)
  • Pétrographie

Subject field(s)
  • Geomorphology and Geomorphogeny
CONT

Subsequent rifting of the Pan-African mountain belt resulted in a series of grabens, which were infilled with Upper Precambrian-Cambrian molasse. These are the precursor basins for the Palaeozoic sediments which cover much of North Africa

Record 6 2006-08-19

English

Subject field(s)
  • Geological and Other Scientific Names
OBS

A same designation could refer to a geographic or a geologic entity, sometimes with a slight variant in spelling or writing. It is important to distinguish one from the other and write each correctly according to the given context.

OBS

Located in the Flin Flon-Snow Lake Region, Western Canada.

OBS

A coarse, west-derived molasse that lies east of the Athabasca Group.

French

Domaine(s)
  • Noms géologiques ou scientifiques
OBS

La règle concernant la majuscule au générique d'un nom géologique demeure imprécise. Habituellement, les noms de divisions stratigraphiques portent la majuscule et les entités de moindre importance n'en portent pas.

OBS

Une même désignation peut se référer à une entité géographique et à une entité géologique, parfois avec une légère variante. Il importe de bien distinguer l'une de l'autre et d'utiliser la graphie correcte selon le contexte.

OBS

Molasse grossière à source occidentale qui s'étend à l'est du Groupe d'Athabasca.

Record 7 2002-06-12

English

Subject field(s)
  • Tectonics
CONT

... the main orogenic phase occurred a few million years later with a sudden onset of flysch-type sedimentation. This is clear evidence of the uplift of the source area and/or deepening of the basin.

CONT

The main orogenic phase during which nappes and deep-seated granite bodies originated, first commenced during the Oligocene while the molasse sedimentation in the southern Himalayan foredeep and in the zone between the Karakoram and western Himalaya, as well as that between the southern part of the Tibetan Highland and the Himalaya, lasted from the Lower Miocene to the Lower Pleistocene. Only as late as during the Quaternary did the period of predominant uplifting begin in the Himalaya and the Karakoram.

CONT

As a counter effect Central and Southern Tunisia are lifted up and eroded, resulting in thick sandy formations. Mid and Late Miocene are paralic in the coastal area with a hot climate indicated by mangroves and evaporites, specially at the end of Messinian. Strong collisions continue from Tortonian to the late Pliocene giving large conglomeratic series. The last and main orogenic phasis is Early Pleistocene.

French

Domaine(s)
  • Tectonique
CONT

À l'Éocène moyen, la phase orogénique principale des Pyrénées s'accompagne d'une grande phase d'érosion et de décapage des couvertures géologiques (flyschs) qui se poursuit jusqu'au milieu du Tertiaire.
