  • Fluvial deposits of the middle Kuiseb valley, Namibia
  • A variety of fluvial deposits of various ages occur in the middle Kuiseb valley in arid Namibia. The characteristics, lithology, spatial and altitudinal relationships and possible chronology of these fluvial deposits are considered. Conclusions
  • are at variance with earlier chronologies as it is postulated that major fluvial activity is probably mid-Tertiary at latest. (AJC).

  • This study investigates the origin and regional tectonic implications of high-altitude Plio-Quaternary fluvial deposits developed over the Bozdağ horst. A total of 23 deposits occur near the modern drainage divide comprising fluvial to occasionally
  • lacustrine deposits. Morphological, lithological, deformational characteristics of these deposits and the drainage system of the area all suggest that the deposits were formed due to uplift and southward tilting of the Bozdağ horst. These deposits

  • Ice-pushed Lower and Middle Pleistocene deposits near Rhenen (Kwintelooijen): sedimentary-structural and lithological/granulometrical investigations
  • Lower Pleistocene deposits fluvial middle Pleistocene deposits and fluvial mass flow and alluvial fan Saalian deposits are involved. The most complete thrust sheets are up to 25 m thick.
  • In the Kwintelooijen sandpit, located in the inside of a large ice-pushed ridge, a number of thrust sheets are exposed which were formed by pushing inland ice during the Saalian glacial time. In these glaciotectonic units periglacial and fluvial
  • Textural features of fluvial and aeolian deposits in the Mark River valley (Belgium)
  • The valley of the river Mark (Belgium) is filled with deposits of fluvial and aeolian origin accumulated during the Pleniglacial or the beginning of the Late Glacial, not later than 12.000 yr BP. The aim of the investigations was to determine those
  • textural features of the deposits that would best differentiate them into fluvial and aeolian ones. The analyses of granulometric composition, of the quartz grain abrasion, and of heavy mineral composition were performed as well as the analysis of quartz

  • Using quartz grain size and shape analysis to distinguish between aeolian and fluvial deposits in the Dallol Bosso of Niger (West Africa)
  • Factor analysis of grain-size distributions gave four sand end-members that can be related to fluvial transport dynamics operating when the sediments were initially deposited. The medium to fine (and more angular shaped) sand fractions are being
  • reworked by wind. Aeolian deposits were well sorted whereas fluvial deposits were poorly sorted in both size and shape. Although gross-shape characteristics (lower harmonics of Fourier series expansion) indicated a common source rock for all sands
  • , the aeolian sands were well rounded whereas the fluvial sands tended to be more angular (upper harmonics of Fourier series).

  • New research from the Shoalhaven deltaic plain prompts revision of ideas on fluvial deposition in coastal New South Wales. Thermoluminescence (TL) analysis indicates that there were at least 2 and probably 4 phases of Pleistocene deposition spanning
  • much of Last Interglacial and Glacial times. Holocene infilling was faster than previously thought. The pattern of channel development which has controlled fluvial sedimentation and the apparent impact of tsunami surges on these Holocene features
  • Size and position matter : riparian plant establishment from fluvially deposited trees
  • The sprouting of fluvially deposited trees is an important process for floodplain woodland regeneration along dynamic rivers. This paper investigates how tree size and relative elevation of the location of fluvially deposited trees affects
  • their survival. The survival of newly deposited trees along the River Tagliamento, Italy, was monitore over 3 field campaigns (2001, 2003 and 2005). A significant negative correlation was found between relative elevation and tree survival, while tree length

  • A database of radiocarbon dates from Late Holocene fluvial environments in Spain was critically analysed in order to obtain a fluvial chronology for this period. The principal types of depositional represented in the record were slackwater flood
  • deposits, alluvial overbank facies and alluvial channel facies. The sedimentary context of each date was classified in order to identify those samples that specifically dated change in the fluvial environment. The results indicate that in Mediterranean

  • Changing fluvial style of periglacial lowland rivers during the Weichselian Pleniglacial in the eastern Netherlands in Periglacial processes and landforms.
  • Analysis of the fluvial deposits occurring in the Weichselian basin fills in the Twente region contributes valuable information to the interpretation of last Glacial paleoenvironments. Although quantification of paleohydrologic data is difficult
  • , if not impossible in these deposits, the fluvial architecture provides sufficient clues for a general interpretation of the fluvial system in terms of discharge regimes.

  • A unique clustering of layered streamlined forms in Athabasca Valles is hypothesized to reflect a significant hydraulic event. The forms, interpreted as sedimentary, are attributed to extensive sediment deposition during ponding
  • and then streamlining of this sediment behind flow obstacles during ponded water outflow. These streamlined forms are analogous to those found in depositional basins and other loci of ponding in terrestrial catastrophic flood landscapes. Likewise, the streamlined forms
  • Sedimentology and facies distribution of Pleistocene cold-climate aeolian and fluvial deposits in the Roer Valley Graben (southeastern Netherlands)
  • This paper describes and interprets the sedimentary facies that can be recognized in the fine-grained deposits of the Boxtel Formation in the Roer Valley Graben and explains the vertical and lateral facies distribution. It is demonstrated
  • that the facies characteristics and architecture are related to a combination of local subsidence and the generally cold-climate conditions during and after deposition.
