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.

OBS

Une plate-forme est une région de transit de sédiments. Seuls les sédiments relativement grossiers sont stables, les autres sont en état de transport. La stratification y est irrégulière, inégale, à ripple-marks et légèrement entrecroisée. L'auteur nomme «unda» le milieu de dépôt correspondant [...]

English

Subject field(s)
  • Chemical Engineering
  • Geology
OBS

Rich (1951) used the framework of shallow water, sloping bottom, and deep-water conditions (undaform, clinoform, and fondoform) to discriminate sediments formed under different environmental conditions. This leads to undathem, clinothem, and fondothem as terms applied to lithosomes formed under the corresponding conditions.

La stratification y est irrégulière, inégale, à ripple-marks et légèrement entrecroisée. L'auteur nomme "unda" le milieu de dépôt correspondant et "undathèmes" les dépôts qui s’y forment.
