Abstract
The area under investigation is located between latitudes 27° 50’ x28° 20’ N and longitudes 30° 50’ - 31 ° 10’ E, east El Minia Governorate. The textural characteristics and mineralogical composition of the studied Quaternary sediments are exposed in six wadies at east EI-Minia have been investigated. The studied sediments are moderately to poorly sorted, meso-kurtic to lepto-kurtic and generally positively skewed.
The granulometric analysis indicates their deposition under calm water conditions and low gradient streams of river processes. The surface texture investigation of the studied Quaternary sediments reflect both earlier aeolian stage in deposition followed by a later fluvial one. Heavy mineral fractions indicate a widely origin related to both the basement complex and pre-existing sedimentary rocks. The distribution of clay minerals within the studied Quaternary sediments may confirm that, the studied sediments were deposited in fluviatile regime and mainly controlled by source materials, burial, diagenesis and climatic conditions.
The facies study on the clastic deposits of the research area, pointed out to several lithofacies, including; the coarse, medium and the fine grains clastic facies. The studied facies are subdivided into sublithofacies. These are farther subdivided into 11 microfacies bouldary limestone oligomictic conglomerate, bioclastic sandstone, silty clayey fine sand, bioclastic siltstones, the high organic or very fine mud, limey claystone to mudstone, the mottled clay and the kaolinitic claystone microfacies. The lithostratigraphic analysis and their paleo-depositional provenances were studied.
