Desert ; Dune ; Geochemistry ; Grain size distribution ; Heavy minerals ; Mexico ; Sand ; Sedimentology ; Sonora ; Trace-element
The AA. focus their attention on the provenance of the inland desert and coastal dunes of the Altar Desert, based on the sedimentology, modal analysis and geochemistry of major and trace elements of the sands. The study uses grain size parameters

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.

The study of loess varieties in Hungary is supplemented with the granulometric analyses of key loess profiles. A new system of sedimentological indices has been introduced by a team in the Geographical Research Institute. The index of fitness grade
was first applied in Germany for eolian deposits in Lower Rhine-Vestphalia, while the degree of weathering was employed for loess in China. These indices are combined with conventional sedimentological ones in environmental reconstructions. Index values

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

Morphology, sedimentological characteristics and origin of a fossil rock glacier on Muckish Mountain, northwest Ireland
A large talus-foot debris accumulation on Muckish Mountain is interpreted as a fossil rock glacier rather than a glacial moraine as previously suggested. Sedimentological characteristics indicate that the debris accumulated initially as talus. Rock
