Die voorkoms en betekenis van hangterrasse in die Hartbeespoortdamomgewing. (The existence and significance of slope terraces in the vicinity of the Hartbeespoort Dam)
The existence of four slope terraces from the freeface over the southern slope of the Magaliesberg was ascertained by means of slope analysis. These terraces are covered by colluvium which has had no significant influence on the prominence
of the terrace. In the same vicinity, on the Daspoortrand pediment, it was possible to deduce that the fine sediments originating from the Daspoort quartzite totally covered a small valley as well as a terrace on the middle pediment of the Daspoortrand
. These terraces were correlated with the Early and Late Tertiary erosion surfaces respectively. (AJC).
Types de terrasses fini-glaciaires dans le Nord-Mayo et l'Ouest-Sligo (Irlande occidentale). in Colloque AFEQ, Paris 1983. (Types of terraces related with melting-ice processes in North-Mayo and West-Sligo (western Ireland))
The piedmonts and intramountain basins in North-Maysand West-Sligo were filled in the Late Pleistocene by the eastern ice of the Midlandian Glaciation. Varied types of terraces are related with the erosive and depositional meltwater processes
of the recessive ice-sheet: 1) frequent terraces in the pleniglacial till cover by vertical cutting of the meltwater channels| 2) frequent stepped juxtaglacial-lake terraces by glacial obturations| 3) very few proglacial outwash terraces. The fresh shape
Zur Stratigraphie der Elbterrassen und glazigener Bildungen der Elstereiszeit bei Dresden. (On the stratigraphy of the Elbe Terraces and glacigenous formations of the Elsterian near Dresden)
On the base of new drilling results, Elsterian formations are described. They allow to show new possibilities for the classification of Elbe river terraces and the origin of the Elbe valley. (HL).
Mise en place des basses terrasses holocènes dans les Matmata et leurs bordures (Sud-Tunisien). in Colloque AFEQ, Paris 1983. (Emplacement of the lower terraces in the plateau of Matmata and its borders (southern Tunisia)
The genetic relationship of these lower sand-silty terraces with the in-situ loesses of plateau and the colluvial loesses of slopes is shown by sedimentological criteria (progressive disappearance of the clayey/fine silty fraction of the initial
loessic stock| relative concentration of the detrital palygorskite proportion in the fluviatile terrace sediment). The emplacement of these terraces is in good agreement with the palaeoenvironmental holocene evolution of southern Tunisia.
Les rapports entre les terrasses et l'évolution des versants dans les Aurès (Algérie). in Colloque AFEQ, Paris 1983. (Terraces and slopes evolution in the Aures mountains (Algeria)
In the Aures mountains, terraces are accumulated on the course of a humid phase. During the accumulation, pediments, fans and mudslides are formed. Then, when aridity appears, calcretes, eolian sands and gypsum crusts settle.
Terrasses fluviatiles au Proche-Orient. in Colloque AFEQ, Paris 1983. (Fluviatile terraces in Near East)
Field survey in Lebanon, Syria and Jordan proves essentially that the terraces of the coastal rivers were built during marine regressions. Those of the inland rivers were roughly synchronous, as evidenced by the typology of the artefacts and various
Les terrasses fluviatiles au sud des Alpes. in Colloque AFEQ, Paris 1983. (Fluviatile terraces in south of the French Alps)
Some typical examples of Quaternary terraces systems in South of the Alps are presented. They show variations in the fluvial dynamics evolution in accordance of their localization (alpine or provençal area) on the one hand, in accordance
Signification dynamique et climatique des formations et terrasses fluviatiles dans l'Europe du Nord-Ouest. in Colloque AFEQ, Paris 1983. (Dynamic and climatic significance of fluviatile deposits and terraces in northwestern Europe)
Terrasses fluviatiles du Pléistocène moyen en France septentrionale: signification dynamique et climatique. in Colloque AFEQ, Paris 1983. (Middle Pleistocene fluviatile terraces in northern France: dynamic and climatic significance)
The typical sequence of the lower terrace of Somme valley at Longpré-les-Corps-Saints (Somme, France) shows two series of pleniglacial formations (the lower being fluviatile) separated by deposits and soils which are related to the evolution
of the penultimate Interglacial-Early Glacial. The erosion into the valley which is responsible of the terrace morphogenesis occurs formerly to the slope pleniglacial deposit corresponding to a new slope morphology. Similar data are furnished by the paleolithic site
of the lower terrace of Scarpe Valley at Biache-Saint-Vaast (Pas-de-Calais) which is also disturbed by faults.
La terrasse moyenne de la Moselle dans les Vosges: essai de reconstitution de la genèse d'une terrasse fluviatile par rapport au cycle climatique quaternaire. in Colloque AFEQ, Paris 1983. (The middle terrace of the river Moselle (Vosges, France
The two graded megasequences observed in the alluvial deposits (middle terrace) of the river Moselle, with the help of other sedimentological indicators, allow the author to correlate sedimentation periods and climatic cycle: sedimentation occurs
Signification dynamique et climatique des formations et terrasses fluviatiles dans un environnement de moyenne montagne. in Colloque AFEQ, Paris 1983. (Dynamic and climatic significance of the fluviatile formations and terraces in a middle altitude
Sedimentary and erosional phases responsible for the formation of fluviatile terraces are studied in a middle altitude environment. The importance of neotectonic phenomena is revealed by the shaping of alluvial channels as also their sedimentary
Chronologie des basses terrasses de l'Allier en Grande Limagne (Puy-de-Dôme, France). in Colloque AFEQ, Paris 1983. (Chronology of lower terraces of the Allier river in Grande Limagne (Puy-de-Dôme, France))
After the deposit of Würmian alluvium (lower terrace of 15-20 m), one can distinguish two phases of in cutting during the Late Glacial followed by a period of alluviation which stops during the Atlantic. Then, the Allier river hollows her present
Les terrasses alluviales dans les petites Pyrénées et l'avant pays molassique: les conditions de leur mise en place. in Colloque AFEQ, Paris 1983. (The terraces in the Pyrenean piedmont: conditions of alluvial setting)
Soils and particularly weathering rocks data on alluvial gravels tends to assomption of a non-synchronism for alluvial setting between upper and lower part of the basin. With regard to a lower terrace so called basse plaine, this assumption
