the alluvial fan of shahdaad in derakhtangaan river is one of the biggest alluvial fans in a dry area in northeastern kerman. this alluvial fan has been formed due to different material erosions in the drainage basin of derakhtangaan river and lying of these materials in the extreme part of this basin called dasht-e-lut (the plain of lut). the region which has been studied in this research is o...

The Blue Nile Basin, situated in the Northwestern Ethiopian Plateau, contains 1400 m thick Mesozoic sedimentary section underlain by Neoproterozoic basement rocks and overlain by Early–Late Oligocene and Quaternary volcanic rocks. This study outlines the stratigraphic and structural evolution of the Blue Nile Basin based on field and remote sensing studies along the Gorge of the Nile. The Blue ...

The research aims to show the validity of quaternary sediments in north Al-Shirqat district as filling materials for dams. Samples were collected from (4) stations representing these region. Geotechnical examinations showed that this region are clay low plasticity (CL) and alluvial (ML) having values ​​of specific weight ranged between (2.65-2.71). Chemical analyzes gypsum ranges (1.35-8.08) %,...

We investigated the Late Quaternary activity of a major, crustal fault affecting southern sector Central Apennines, i.e., Roveto Valley Fault (also known as Liri fault). This chain was hit by numerous M>5 historical seismic events. For some these, e.g., 1654 one (M w 6.33), causative seismogenic source has never been conclusively defined. Within this seismotectonic framework, recent is s...

The Mesopotamian Plain is part of the Mesopotamia which extends for vast area bigger than plain. plain almost flat and lowland, has clearly defined physiographic boundaries with other surrounding provinces. a huge accumulation geomorphologic unit, where fluvial, lacustrine, Aeolian landforms prevail; fluvial units being abundant among others. However, estuarine marine forms also are developed, ...

quaternary sediments have occupied most of the agricultural and natural resources of urmia region. recognition of physicochemical and mineralogical properties of these soils is essential to optimum and stable use of these lands. in this study, eight soils profiles excavated on quaternary sediments of urmia region were investigated. the results showed that little thickness and evolution of studi...
