Record 1 2018-02-23

English

Subject field(s)
  • Geomorphology and Geomorphogeny
  • Hydrology and Hydrography
CONT

Isolated basin marsh : These marshes occupy topographically-defined basins formed by glacial erosional and depositional processes, slumping, solution or ablation of unconsolidated deposits and bedrock. There are no surface inlets or outlets. The marsh receives water from rain, snowmelt, surface runoff, and groundwater discharge. The length of time that the marsh retains water is dependent upon water exchanges with the groundwater table, the permeability of geological substrates, and water losses by evaporation. Water may be saline with saline rings around the periphery in arid regions and fresh in non-arid regions. It is possible to have freshwater or saline isolated basin marshes.

Domaine(s)
  • Géomorphologie et géomorphogénie
  • Hydrologie et hydrographie
CONT

Marais de bassin isolé : Ces marais se trouvent dans des bassins aux reliefs bien délimités formés par les processus d'érosion et de dépôts glaciaires, le «slumping», la dissolution ou l'ablation de dépôts non consolidés et de substratum. Les ruisseaux et les chenaux de surface sont absents. L'eau du marais provient des précipitations, de l'eau de fonte, de l'écoulement de surface et de l'écoulement de l'eau souterraine. La durée de la rétention de l'eau par le marais dépend des échanges aqueux avec la nappe phréatique, de la perméabilité du substratum géologique et des pertes d'eau par évaporation. L'eau peut être salée, avec des anneaux salins autour de la périphérie dans les régions arides et de l'eau douce dans les régions non arides. Les marais de bassin isolé sont à eau douce ou à eau salée.

Subject field(s)
  • Geomorphology and Geomorphogeny
  • Oceanography
OBS

In 1951 John L. Rich was the first to propose that the depositional settings of sediment accumulation on the shelf, slope, and bottom be(1) unda for shallow water overlying the shelf,(2) clino for the deeper water overlying the slope, and(3) fondo for the deepest water covering the bottom of the basin(Friedman(2001). Rich suggested the terms(1) undaform for any surface underlying an unda environment;(2) clinoform for any surface underlying a clino environment;(3) fondoform for any surface underlying a fondo environment.... Following this approach Mitchum(1977) proposed that clinoform surface be used for the sloping depositional surface that is commonly associated with strata prograding into deep water.

OBS

Rich chose three Greek words as general ones for the three critical environments. These are (1) unda for the shallow water overlying the shelf, (2) clino for the deeper water overlying the slope, and (3) fondo for the deepest water covering the bottom of the basin.

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

A subaqueous landform, such as the continental slope of the ocean or the foreset bed of a delta.

CONT

A clinoform is a seaward-dipping surface of a prograding sediment body that consists of a gently dipping topset, a steeply dipping foreset, and a gently dipping bottomset. The topset consists of fluvial and subaqueous environments coupled at the shoreline. Clinoforms are ubiquitous in modern depositional systems and are the fundamental constructional units of stratigraphic sequences.

Rich was the first to propose that the depositional settings of sediment accumulation on the shelf, slope, and bottom be(1) unda for shallow water overlying the shelf,(2) clino for the deeper water overlying the slope, and(3) fondo for the deepest water covering the bottom of the basin(Friedman(2001). Rich suggested the terms(1) undaform for any surface underlying an unda environment;(2) clinoform for any surface underlying a clino environment;(3) fondoform for any surface underlying a fondo environment....
