The Adigrat Sandstone is found in the Blue Nile Basin, North Western plateau of Ethiopia.It was formed because of jurassic marine transgression came from the south-east (Daniell, 1974. It has been analyzed to determine their provenance composition, paleoweathering and paleoclimatic scenarios. Samples of this sandstone are slightly variable in composition and on QFL diagram; most o the samples are plotted in subarkose and lithic subarkose fields. The CIA, PIA and CIW values for this sandstone and the A-CN-K diagram agreeably suggest that source rocks experienced intense chemical weathering under hot and humid tropical to sub-tropical climate. Mineralogical evidence suggests that plutonic and metamorphic rocks were major contributing source rocks. However, recycling of the sediment is also an inevitable.
