We here present the first comprehensive provenance study of Sahara Desert using a combination multiple proxies and state-of-the-art statistical analysis. Our dataset comprises 44 aeolian-dune samples, collected across region from 12°N (Nigeria) to 34°N (Tunisia) 33°E (Egypt) 16°W (Mauritania) characterized by bulk-petrography, heavy-mineral, detrital-zircon UPb geochronology analyses. A set too...

Transmission lines located in the desert are subjected to desert climate, one of whose features is sandstorms. With long accumulation of sand and with the advent of moisture from rain, ambient humidity and dew, a conductive layer forms and the subsequent leakage current may lead to surface discharge, which may shorten the insulator life or lead to flashover thus interrupting the power supply. S...

Within areas of the Chihuahuan Desert dominated by honey mesquite bushes (Prosopis glandulosa), soil erosion causes open eroded patches and the formation of large coppice dunes. The airflow patterns around the dunes and through the open areas are correlated with sand flux and erosion. This study uses wind velocity simulations from the Quick Urban and Industrial Complex (QUIC) model in combinati...

The xerophytic desert shrub Haloxylon ammodendron (C. A. Mey.) Bunge. is distributed naturally in Asian and African deserts, and is widely used for vegetation restoration in the desert regions of Northern China. However, there are limited long-term chrono-sequence studies on the impact of changed soil properties and vegetation dynamics following establishment of this shrub on mobile sand dunes....

Sand glass deposits was located in the mid of the Western Desert of Iraq. It is situated within Rutba Formation (Ceno-manian). Ancient traditional mining method is still used in exploitation the unconsolidated white glass sand from glass sand quarry. The overburden thickness ranges from 2 to 4 m in average. Termite hills were observed around the glass sand quarry extending far from the quarry a...

the result of wind dynamic (capacity and potential) is transport of soil or sediment particles and subsequent formative desert landforms based on the severity of erosion or sedimentation. the khartouran region, because of its geology, geomorphology and climatology conditions is a special place in the arid region on the closed basin of dasht-e-kavir. it is evident that the ecosystem balance of t...

Abstract In the construction sector, non-renewable world resource of sand is largely used to produce mortar and concrete. It has been estimated that over 10 billion tons have produced, with 1.2 in concrete last decade, which leads a progressive reduction available materials environmental impacts. Since desert resources are abundant arid region Adrar (Southern Algeria), it would be viable use de...

In contrast to the body of work in more mesic habitats, few studies have examined boundary processes between natural and anthropogenic desert landscapes. Our research examined processes occurring at boundaries between a desert sand dune community and an encroaching suburban habitat. We measured responses to an anthropogenic boundary by species from multiple trophic levels, and incorporated meas...
