Open-framework gravels (OFGs) form common lithofacies of alluvial fans. However, inferences their mechanisms transport and deposition, controls on distribution in alluvial-fan successions, remain difficult, limiting our ability to interpret the environmental significance such deposits predict distributions ancient successions. From an applied standpoint, predictions are important development hy...

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...
