Cyclicity and sequence stratigraphy of syn-rift Late Neogene mixed carbonates-siliciclastics of the area between Wadi Zug El Bohar and Wadi Dabr, Red Sea, Egypt.

2018-09-26 07:07:32 Keywords Pliocene, sequence stratigraph, Neogene, carbonates, Cycles, ,
Cyclicity and sequence stratigraphy of syn-rift Late Neogene mixed carbonates-siliciclastics of the area between Wadi Zug El Bohar and Wadi Dabr, Red Sea, Egypt.
THE LATE OLIGOCENE SEDIMENTS ARE REPRESENTED BY MIXED SILLICICLASTICS AND CARBONATES DEPOSITED UNDER CYCLICAL DEPOSITIONAL CONDITIONS. BASED ON SIZE VARIATIONS AND MIXING OF FACIES, SIX DIFFERENT TYPES OF CYCLES ARE RECOGNIZED; FINING-UPWARD CYCLES, COARSENING-UPWARD CYCLES, MIXED FLUVIAL-LACUSTRINE CARBONATE CYCLES, MIXED FLUVIAL-RESTRICTED MARINE CARBONATE CYCLES, MIXED SILICICLASTIC-OPEN MARINE CARBONATE CYCLES AND DOMINANTLY OPEN MARINE CARBONATE CYCLES. THE DEVELOPMENT OF CYCLIC SEDIMENTATION ... Read more

The problem of the Late Miocene-Early Pliocene boundary along the Red Sea coastal area between Quseir and Mersa Alam, Egypt.

The problem of the Late Miocene-Early Pliocene boundary along the Red Sea coastal area between Quseir and Mersa Alam, Egypt.
The Late Miocene- Early Pliocene succession of the Red Sea coastal area between Quseir and Mersa Alam is differentiated, from base to top, into: Abu Dabbab Evaporites and the overlying informal rock units (A), (B) and (C). The characteristic features of Unit (A) (Lithofacies, mineralogical, chemical compositions, fossil content as well as field relations) suggest that these sediments represent the ... Read more

Comparative Studies of Recent and Fossil Echinoid Jacksonaster depressum (L. Agassiz) from the Northern Bay of Safaga, and Late Pliocene rocks, Red Sea coast, Egypt.

2018-09-05 21:22:01 Keywords Red Sea coast, Safaga bay, Pliocene, Jacksonaster depressum, Echinoidea,
Comparative Studies of Recent and Fossil Echinoid Jacksonaster depressum (L. Agassiz) from the Northern Bay of Safaga, and Late Pliocene rocks, Red Sea coast, Egypt.
STATISTICAL CORRELATION, ONTOGENETIC DEVELOPMENT AND SEXUAL DIMORPHISM HAVE BEEN STUDIED IN RECENT AND FOSSIL SPECIMENS OF JACKSONASTER DEPRESSUM (L. AGASSIZ, 1841). A LARGE NUMBER OF DEAD AND LIVING TESTS OF THIS SPECIES HAVE BEEN COLLECTED FROM BOTTOM SEDIMENTS OF THE SAFAGA BAY, RED SEA, EGYPT. OUT OF TWO HUNDRED SPECIMENS, ONE HUNDRED AND SEVENTY SEVEN (20 LIVING AND 157 DEAD, ... Read more
