The provenance and history of Abu Muharak barchan sands (Kharga Depression) inferred from textural, mineralogical, and geochemical perspectives

Abstract The current study deals with textural, mineralogical, and geochemical characteristics of the barchan dune sands Abu Muharak belts in Kharga Depression. is longest belt Western Desert Egypt. Sand samples from 37 sites were texturally, petrologically, chemically analyzed. Our goals to interpret provenance terms grain size, petrology, geochemistry correlate these data proposed source such as Nubian sandstone, Pleistocene alluvial, Holocene lacustrine sediments well ancient aeolian deposits exposed at present concludes that Moghra sandstone main local contributions alluvial weathered
