Archeological site ; Cape Province ; Dating ; Geochemistry ; Isotope dating ; Quaternary ; Sedimentology ; South Africa ; Stratigraphy
This paper synthesizes the interpretations of the new stratigraphic, faunal, sedimentological, and radiometric data and offers a considered statement on the age of the Taung australopithecine skull.
Alluvial cone ; Arid area ; Canada ; Gelifluction ; Periglacial features ; Permafrost ; Sedimentology ; Snow
The objectives of this study are to describe the morphology and sedimentology of an alluvial fan, the Mount Goodenough North fan, in a permafrost region; and to interpret the processes responsible for the development of the fan, using both direct
observations and inferences from fan morphology and sedimentology.
Differential bed sedimentology and the maintenance of riffle-pool sequences
Carrying capacity ; Devon ; England ; Fluvial processes ; Model ; River bed ; Sedimentology ; Statistics ; United Kingdom
The purpose of this paper is to clarify several aspects of the sedimentology of riffle-pool sequences, and to suggest how these both reflect and control riffle-pool stability in the presence of spatial differences in the turbulent near-bed flow
The fine-grained sediments of Wadi Firan (Sinai, Egypt): origin and sedimentology
Aeolian features ; Arid area ; Egypt ; Fluvial terrace ; Grain size distribution ; Mineralogy ; Palaeo-environment ; Sediment transport ; Sedimentology
The geomorphological and sedimentological field studies as well as the mineralogical investigation of 80 silty-clayish samples from the terraces of the Wadis Firan and Esh Sheikh (southern central Sinai) lead to new conceptions about
the petrogenesis of these sediments. The altimetric measurements, the geomorphological and sedimentological observations allow the reconstruction of (at least) eleven successively occuring basins where the sedimentation took place in a lacustrine environment
Morphological, sedimentological and tectonic features of Diamante-M. Carpinoso marine terrace flight (Tyrrhenian coast of Northern Calabria, Italy)
of terraces is evident in the Diamante area. The aim of this study was to define the type of tectonics that acted in the area and to determine its effects, based on morphologic, morphotectonic, sedimentologic and stratigraphic evidence.
Ice-sheet dynamics and subglacial meltwater regime inferred from form and sedimentology of glaciofluvial systems: Victoria Island, District of Franklin, Northwest Territories
The aim of this paper is to describe and interpret glaciofluvial complexes at three sites on Victoria Island and to use these to assess the formative melt-water conditions. Differences in esker morphology and sedimentology and landform associations
sedimentology of anastomosed and wandering gravel-bed rivers. The scale problems of facies analysis may be overcome by employing architectural element analysis in conjunction with modern geophysical methods such as shallow reflection seismology and ground
-penetrating radar. Futur research should focus on devising specific tests of element-scale sedimentological relationships based on the contemporary fluvial environment.
is discussed with respect to accuracy and repeatability. The methods covered include sedimentological evidence, botanical evidence, historical sources, planimetric resurvey, repeated cross-profiling, erosion pins and terrestrial photogrammetry. Prospects
Sediments of 13 piston cores from opposite continental slopes of the South China Sea, off southern China and Sabah (northern Borneo), were analysed by sedimentological methods and dated by oxygen isotope stratigraphy. The resulting high
This paper presents the various environmental parameters and sedimentological processes that contribute to the occurrence and enhancement of the problem of sand encroachment in Kuwait and discusses concepts relevant to control measures.
