Subsurface Lower–Middle Miocene Biostratigraphy Of Ras El-Ush Oil Field, G. Zeit Area, Gulf Of Suez, Egypt, A. Hewaidy, M. Ayyad, Ahmed Abdallah Dec 2018

Subsurface Lower–Middle Miocene Biostratigraphy Of Ras El-Ush Oil Field, G. Zeit Area, Gulf Of Suez, Egypt, A. Hewaidy, M. Ayyad, Ahmed Abdallah

Al-Azhar Bulletin of Science

The Lower-Middle Miocene succession penetrated in four wells in Ras El Ush oil field (Ras El Ush 7,8,12 and 14), East G. Zeit, Gulf of Suez is examined in detail for its foraminiferal and nannofossil contents. The Rudeis, Kareem and Belayim formations are distinguished. One hundred and fifty-one foraminiferal and forty-five nannofossils species are identified. Three planktonic foraminiferal and two nannofossils biozones are distinguished and integrated. The planktonic foraminiferal zones are Catpsydrax dissimilis (M3) of early Miocene (Burdigalian) age, Praeorbulina sicana (M5) of early-middle Miocene (Burdigalian-Langhian) age and Fohsella peripheroacuta (M7) of middle Miocene (Serravallian) age. The nannofossil biozones are …


Suitability Of Feldspar-Sand Deposits As Raw Materials For The Production Of Ceramic Tiles At Wadi El-Yatima – Wadi El-Tuleia District, Central Eastern Desert, Egypt, M. El-Mezayen, M. El-Desoky, D. Abayazed, M. El-Bery Dec 2018

The function of feldspar in ceramic bodies is that of a flux and it takes a part in physio-chemical reactions with other crystalline phases. Two formulations were studied on laboratory scale and on production simulation of tile making process, compared with standard one. The tiles made up of feldspar-sand as raw materials and fired between 1125°C (wall tile) and 1185°C (floor tiles). The properties of wall tiles were found to have the water absorption are of 13.43 - 16.25%, bulk density are of 1.65-1.68 g/cm3, apparent porosity are of 22.24-26.82%, linear shrinkage are of 0.01-0.06%, bending strength are of 18.45-23.08 …
