Abstract: soil profiles were select representing the soils of EISalhiya project. These soils were studied in order to evaluate their genesis,formation and development. Studied grain size distribution and statistical parameters indicate that these soils have mainly moderately to poorly sorted sediments with near symmetrical to fine skewed materials and leptokurtic to mesokurtic pattern . These parameters indicate that these soils are formed under water or both water and wind action. With regard to the petrographic examination , data show that the light fraction are composed essentially of Quartz. The other associated minerals such as Feldspars are detected in small amounts. On the other hand, heavy minerals are dominated by opaque minerals. The non-opaque minerals are dominated by pyroboles ( pyroxenes+amphiboles ) and epidote. Zircon, rutile and tourmaline are presence in moderate amounts. Garnet J staurolite, kyanite and silimanite are found in less pronounced amounts. Moreover J the results indicate that these soils are formed from heterogeneous materials either due to their multiorigin or due to a subsequent varh,tion along the course of se(iimentation. Therefore, they are pedologically considerd as weak developed'and young.
