The Nubia Sandstone Nubia Group , Western Desert, Egypt An OverviewYogeshIJTSRD
No information was given about the outcropping of the Nubia sandstone in the Great Sand Sea in the Western Desert of Egypt and actually very scarce and insufficient information has been written on the geology of the Great Sand Sea. Since 1931 the Great Sand Sea has been described as being formed of many parallel longitudinal sand dunes which cover ~72000 km² and are bounded in the south by the Gilf El Kebir Nubia Sandstone Plateau and in the north by Siwa Oasis. However, recently it has been found by the author and his collaborators that the rock units exposed on surface in the Great Sand Sea are belonging to the younger members of the fluviatile Cretaceous Nubia Sandstone Group. They are not covered by younger marine consolidated deposits but only with a thin veneer of accumulations of free sands originating from the disintegration and breakdown of the Nubia Sandstone bedrock, thus obscuring the original bedrock. The area exhibits a long history of predominantly continental sandstone accumulation and continuous subsiding during the geologic history so that the sequence attains a thickness more than 3500m in the subsurface. The exposed Nubia Sandstone rocks have been formed in different geomorphologic features such as longitudinal parallel sandstone ridges separated by wide flat sandstone tracks, sandstone plateaus and domes, sandstone depressions, plains and valleys. These results make it necessary to review the surface distribution and the lithostratigraphic change both stratigraphic and geographic of the Nubia Group in the Western Desert of Egypt.

Structures and hydrocarbon prospects in emi field, offshore niger deltaeSAT Journals
Abstract The Niger Delta is ranked among the world’s major hydrocarbon provinces in the world. Oil and gas in the Niger Delta are mainly trapped in sandstones and unconsolidated sands in the Agbada formation and the structural traps are not easy to map precisely because they are very slight, not obvious and very complicated. The main aim was to determine the structures and hydrocarbon prospects in Emi-field, off shore Niger Delta using seismic data integrated with well logs. Four (4) horizons namely L1, L2, L3 and L4 were selected and structural maps drawn for each of the horizons. Fault closures of high quality hydrocarbon prospects were identified and delineated. The integration of seismic data with well logs greatly improved the extent of accuracy and exactness of structural maps in hydrocarbon prospects and its development in Emi Field. Key words: Structures, hydrocarbon prospects, Emi Field, Niger Delta

Hydrocarbon potential of the Borno Basin through Electrofacies and depositional environment analysis was carried out from well log and seismic reflection data to reassess the potential of the Basin thereby justifying the huge financial commitment of the Government. The reflection configuration pattern from the seismic reflection lines is characterized by variation from parallel, continuous and strong amplitude to sub parallel, chaotic discontinuous and low amplitude which indicate a variation from a low energy basinal setting of uniform rate of continental deposition to high energy environment of monolithologic deposits. Furthermore, the derivable log signatures shows a variation from serrated mud/sand to serrated blocky to serrated funnel and bell shapes with depth. This imply a stable massive mud/sand rich basinwide environment to an upward regressive sequence of bar deposit followed by a deltaic estuarine clastic sediment to gradual upward transgressive decrease in grain size to a fluvial point bar deposit. These environments identified from the research are known to be hydrocarbon province.

A REVIEW OF GROWTH FAULTS AND ROLLOVER ANTICLINES (A CASE STUDY OF NIGER DELTA) James Opemipo OLOMO
Growth faults and its associated rollover anticlines are generally syndepositional sedimentary structures that result from diastrophism which was contemporaneous with sedimentation. They are special structures which occur abundantly in the Niger Delta & constitute one of the most important hydrocarbon traps in the region .
Despite this abundance, their occurrence is however restricted to the extensional zone of the Niger delta. These structures can be identified from outcrops, seismic data , structure contour maps and well logs. While their propagation history can be constrained by the use of key kinematic tools, such as t-z, d-l and expansion index plots. Although, it has been identified that these structures are target structures in the accumulation of oil and gas, they can also be destructive, especially if they are reactivated after hydrocarbon accumulation.
Hence, it is important for the petroleum explorationist to identify, map their extent and constrain the propagation history of these structures, in order to minimise exploration risk.

Groundwater Sapping Process and Runoff of Old River Systems in the Great Sand...ijtsrd
The present work delineates two main patterns of drainage in the Western Province of the Western Desert. The first pattern was formed by runoff of old river systems and has a restricted geographic distribution on the top surface and slopes of the scarps of the Gilf El Kebir Plateau but it is generally low, intermittent, having a limited duration in the westernmost part of the Great Sand Sea along the Egyptian Libyan borders. The second pattern was and still formed by groundwater sapping process which has a widespread distribution along the slopes of the Gilf El Kebir Plateau, the Nubia Sandstone hills distributed in the Dakhla Basin and the slopes of the widely distributed longitudinal Nubia Sandstone ridges in the Great Sand Sea between the Gilf El Kebir in the south and Siwa Oasis in the north. The phenomenon of lateral flowing of groundwater and its emergence as seeps at the edges of the scarps was and still today the main erosion process that produces major landforms with unique characteristics in the Great Sand Sea. It causes disintegration and breakdown of the Nubia Sandstone bedrock and erosion of the sandstone from the slopes, causing the slopes to be undermined and undergo mass wasting. It is also the predominant mechanism of the growth of the amphitheater headed valleys, and the flat topped surfaces of the upraised plateaus as well as the exploitation of joints and fractures in the Nubia Sandstone bedrock. In addition it is responsible of formation of different types of alcoves in headwalls, spring sites and seepage zones in many valley flanks. Moreover, vast areas of the Nubia Sandstone bedrock of the flat topped plateaus, flat tracks and depressions are found to be eroded, well exposed, clean, and covered by silica debris as a result of intense erosion by the groundwater seepage.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Facies Associations and Evolution of Jurassic Carbonate
Platform, Northern Atlasic Fringe (Ne Algerian)
El Hadj YOUCEF BRAHIM1
Abstract
This study focuses on an area located at the convergence of the allochthonous and the
Atlasic forelands of the Northren Algerian Alpine Belt. The objective of this work is to
reconstruct the drowning history of the Jurassic carbonate platform, and discuss its
relationship with the geodynamic evolution of the Southern Tethysian margin. The
identification and interpretation of drowning events in the platforms can help
significantly to the reconstruction of the depositional, tectonics and eustatic history of
these platforms. The drowning of carbonate platforms was the subject of several
stratigraphic and sedimentological researches in different places on the planet, at
different periods of Phanerozoic times (Read, 1980, 1982, 1985, Kendall & Schlager,
1981, Schlager, 1981, 1989, Santantonio 1993). The stratigraphic interpretation and
correlation of the study area Jurassic series from a few cross-sections, have allowed
the highlighting of the platform physiography during this geological period and
individualizing three stratigraphic units. The synthesis of bio-sedimentological data
reveals diversified facies, involving various deposits environments ranging from
supratidal to deep pelagic peleoenvironments. These facies have evolved within
subsidante carbonate ramp. Thereof has experienced drowning (Toarcian) and filling
(Tithonian, Berriasian) phases, in relation with the eustatic sea level changes at the
global scale and regional tectonics.
