Wadi Ras Baroud area is located in the North Eastern Desert of Egypt, covering an area of about 170km2. It is covered bybasement rocks and dissected by several wadies. The rock assemblages cropping out at Wadi Ras Baroud area comprise, quartzdiorites, granodiorites, syenogranites, dykes and Quaternary sediments filling the streams of the studied area.The grain size analysis and their distribution is a fundamental descriptive measure for clastic sediments. The results of thestatistical parameters are a graphic mean (Mz) ranging from 0.4 to2, inclusive graphic standard deviation (I) ranging from1.2 to 1.9, inclusive graphic skewness (SkI) ranging from -0.3 to 0.22, and inclusive graphic kurtosis (Kg) ranging from 0.7 to1.1. These parameters clear that they are coarse to medium sand, poorly sorted, near to coarse skewed samples, and platykurticand mesokurtic, so these sediments are represented by the turbidity currents environments.The identified minerals in the heavy fractures are represented by magnetite, ilmenite, hematite, garnet, rutile, titanite, zircon,thorite, ferogusnite, and columbite. The radiometric study of the stream sediments of Wadi Ras Baroud indicates that theaverage concentrations of U and Th are 10.38ppm and 25.5ppm respectively
