Wind, in the duration of its erosional process, affects considerable changes in a grain's morphologyfrom its removal (detachment) step to sedimentation. In other word, a grain undergoes its gradualevolution during the transit process. In this project, the maturation of Aeolian sand grains had beenstudied upon as based on texture maturity indicator which includes: sorting, mean size grain, round...

in order to determine the source and critical areas of wind erosion, sistan plain, irifr-e.a method was applied. according to geomorphological investigations, the studied area consists of the following two main units namely: pediment with 1 type and 8 geomorphological facies, and playa with 2 types of flatland and desert type that includes 9 geomorphological facies. on the basis of sediment, th...

The coastline of Essaouira is located on the Atlantic coast Morocco. Bay this city a large sandy system strongly marked by coastal and fluvial dynamics, which makes it perfect example sedimentology processes in area. using satellite imagery allows us to determine morphological evolution mouth Oued Ksob. results study show with areas erosion others accumulation. analysis images distinguish three...

Suspended sediment concentrations in the meltwater of Pindari Glacier were determined at regular intervals in four ablation seasons. The late ablation periods (September 1994 and October 1995) were characterized by a reduced level of sediment concentration, while the sampling periods of early ablation (May 1994 and July 1995) showed very high concentrations of suspended sediment in the meltwate...

Tiapoumdepartment is located in the southeast of onshore basin Cote dIvoire. The sedimentological, granulometric and morphoscopic analyzes carried out on 24 samples from two wells made it possible to determine lithological, paleoenvironmental evolution sediments this area. lithological characterization revealed four facies department Tiapoum. We therefore have direction sedimentation, a thick l...

Dust in the Earth́s atmosphere is increasing, particularly southern Spain. The study of dust properties allows for a hypothesis on origin and provenance dust. This characterised atmospheric deposited city Granada (south Spain) during three spring periods (samples 4PA, 16PA, 28PA, collected 2012, 2013, 2014, respectively). aim was to ascertain characteristics genesis using set methodological tech...
