Mendoza-Espinosa, 2008, On the Libyan Desert Silica Glass (LDSG) transport model from a hypothetical impact structure.

"Fragments of this glass are mostly scattered upon the exposed bedrock of Nubia group (Cretaceous sandstone), on a large surface area along wide corridors between dunes of the Great Sand Sea (SW of Egypt). This distribution is somewhat the result of the tektite fluvial transport occurring throughout the Oligocene-Miocene boundary."
