Detailed geomorphological study of the Nagada region, west of-the Nile enables us to better understand the main landfonns in this part of Upper Egypt. Six geomorphic features are recognized including: the Thebaid plateau; ...

The origin and environment of deposition of the Alamein Dolomite in the El-Razzak Oil Field have been investigated by means of petrographic, chemical and X-ray analysis. The studied rocks are composed of dolomite with ...

Desert roses are crystals which usually take the form of rose petal. They have definite crystal shapes, and enclose sand grains. The desert roses were scattered along an area of about 500m2 in the Ayn Dar area, near Abqaiq, ...

In this study, the effect of porosity and pore filler on the reflection coefficient parameter (R), are well deduced and some mathematical expressions were developed. This leads to the establishment of new expression of (R) ...

The Nile Delta area is geothermally studied to define the behaviour of geothermal gradient in different wells and to determine the distribution of heat in some interesting rock formations. The geothermal investigation of ...

Ten speciecs of family Corallinaceae (Coralline Algae) are herein recorded and described for the first time from the stratigraphic sequence of Mersa Alam, Red Sea, Egypt. Of these, Amphiroa knolli, Jania johnsoni and ...

Thermal derivatographic analysis of the Khuff and Jubaila carbonate rocks shows that calcite and / or dolomite (of calcitic type) are the main constituent minerals. Their differential thermal and thermogravimetric behaviours ...

St. Catherine area, some 900 km in size, is dominated by basement rocks Encompassing old continental gneisses, metasediments, greenstone belt, calc-alkaline granites (G-II-granites), rift-related volcanics (RV), and ...

Ooids are a major constituent of the Pleistocene carbonates along the northwestern coastal ridges of Egypt. For a detailed diagenetic study of the rocks, the Mersa Matruh area was selected. Petrographic examination shows ...

The Jabal Abu Safiyah is a layered intrusion, which was emplaced within volcanosedimentary rocks. It extends in an arc for about 15 km and displays clear layering. The lower zone plagioclases were studied by electron ...
