| Abstract |
This study was carried out to evaluate the formation mode of Wadi Sadd el Gamous soils through studying their grain size analysis; their origin through their mineralogical composition; and their uniformity through studying the ratios of uniformity and weathering.
The grain size analysis and sedimentation pattern stated that most soils are mainly medium sand, poorly to very poorly sorted, fine skewed to strongly fine skewed (with some exceptional cases are near symmetrical or coarse skewed), and leptokurtic or very leptokurtic indicating that water is the apparent major agent in formation most soils and wind may have, sometimes, contributed to the formation.
From the mineralogical analysis of the sand fraction, the light minerals are distinguished by prevailing of quartz indicating soil resistance to the weathering processes. Feldspars are found in relatively small amounts indicating the recent of the studied soils from the pedological point of view.
Heavy minerals are distinguished by a dominance of opaques, while non-opaques are characterized by dominance of pyroboles minerals (pyroxcenes and amphiboles), and epidote. Zircon, rutile and tourmaline are found in moderate amounts. The left minerals are detected in less pronounced amounts.
On the light of the predominance of pyroboles over ubibuitous minerals, the studied soils are considered young form the pedological stand point. Certain heavy mineral such as garnet, epidote and staurolite are mainly divided from metamorphic rocks, whereas the others such as rutile and tourmaline, for instance, are mainly derived from igneous rocks indicating to a multi origin of the parent materials.
Depthwise distribution of the minerals shows an irregular pattern in most soil profiles indicating that the depositional regime rather than the pedological processes is the main reason for such mode.
The index figure of the studied soils does not appear a specific pattern with depth with quite differences from one layer to another indicating a multi depositional regime.
From the irregular trend of uniformity ratios and weathering ratios, the soils under study seem to be formed by multi origin and/or multi depositional regime along the course of sedimentation
