Abstract |
ABSTRACT
The aim of this study is to investigate the sedimentology pattern
and mineralogy of the fine sand fraction in order to evaluate the origin
and the uniformity of soil profiles representing the main geomorphic
units prevailing Wadi El-Sheah, at Assiut governorate.
Data show that the statistical parameters of the particle size
distribution revealed that water or water and wind together play the main
role in transportation and deposition of sediments except that of the
deepest layers of profile H15 (Wadi plain) where wind is the major agent
in the transportation.
With regard to the mineralogical composition of these soils, light
fractions are composed of quartz, but other associated minerals such as
feldspars are found in small amounts. Also, the presences of feldspars
indicate that the studied soils are young from the pedological point of
view.
On the other hand, heavy minerals are detected as opaques,
pyroxenes, amphiboles, epidote in high amounts. Zircon, garnet, rutile
and tourmaline are present in relatively moderately amounts, while the
remaining minerals are detected in less pronounced amounts.
From the pedological stand point, the studied soils are considered
young in the light prominence of pyroboles over ubibutous minerals.
Certain heavy minerals such as garnet, epidote and staurolite are mainly
divided from metamorphic terrain, whereas, the others such as rutile and
tourmaline, for instance, are mainly derived from igneous rocks.
Distribution of uniformity and weathering ratios indicate that the
studied soil profiles are, generally, heterogeneous due to either their multi
origin or their multi depositional regime along the course of
sedimentation
