The composition and texture of beach sediments along continental coastlines vary considerably. Beach sands made completely of carbonate sediments are prevalent along Egypt's Western Mediterranean Coast. Forty-five sediment samples were collected from various locations (El-Dekhela, Kilo-21, Abu Talat, and Sidi Krir) along the Western Mediterranean C...

Economic rare earth element bearing-heavy mineral accommodation in alluvial deposits (stream sediments) is a well-known process caused by varying rates of weathering and transportation of heavy minerals and sediments, which is significant in geochemical exploration. In the present work, stream sediment samples from Wadi Lethi, Sharm El-Sheikh, were...

Integrated petrographical, mineralogical and geochemical studies were carried out on the phosphate beds of the Duwi Formation, which was exposed at the Beida mine. Petrographically, the investigated phosphatic microfacies are Molluscal bioclastic phosphatic grainstone and Biopeloidal phosphatic grainstone, generally composed of phosphatic pellets o...

Quaternary sediments are extensively exposed in Kafr El Gebel area, south of Sphinx, Giza, Egypt. Ten stratigraphic sections have been chosen for studying and sampling. Fifty one samples were collected to investigate sedimentological and mineralogical characteristics of the Quaternary sediments. The statistical grain size parameters revealed that t...

Eight sections were measured and described from the 6th of October City. These sections are I, II, III, IV, V, VI, VII and VIII. Lithostratigraphic sections I to III belong to the post-Miocene (Plio-Pleistocene) paleosols, whereas section V and VI belong to late-Pleistocene (most -recent paleosol) and section VIII belong to Miocene clastic. The seq...

Coastal boulder accumulations are documented along the Mediterranean coast of Egypt between Alexandria and Marsa Matrouh at four distinct sites. The spatial distribution and dimensions of 116 medium to large boulders were documented along four representative coastal profiles. Boulders weigh up to 23 metric tons and are located up to 40 m from the s...

Archaeological sites associated with the Holocene playas in Farafra Oasis were occupied primarily by foragers. Intensive utilization of wild sorghum, originally dated to 6700 yr B.P., has now been pushed back to 7600 yr B.P. Sheep and goats, originating in the Levant, were introduced in Farafra Oasis ca. 6700 yr B.P. The playas were episodically su...

A solution cavern has beeb discovered by me in the limestone plateau (Tarawan Fm) and has been subjected to intensive geological and archaeological investigations. The cavern is situated in the southern slope of the northern plateau of Farafra Oasis.about 100m above the floor of Wadi El Obeid . It consists of three adjoining galleries,measuring on...

Grinding stones excavated at the Predynastic site of HG in Upper Egypt were analyzed, and consist of igneous rocks (rhyolite porphyry, basalt, granite) and metamorphic rocks (marble, quartzite). These rocks were brought to the site in Predynastic times (ca. 4000–3000 B. C.) from the Dokkan Volcanics located in the Wadi Hammamat, possibly as far awa...
