Abstract: The Djoundé locality and vicinities (DV) is located in the Maroua II Subdivision, Far North Region (Cameroon). The conquest of green spaces, the natural resources attracted a significant population that continue to migrate and settle although the occurrence of Mass movement hazards (block and debris falls) in the DV. This paper highlights the assessment of risks related to mass movements hazards in the DV. To that end, important bibliographic research has been done and several laboratory and field studies have been carried out. This allows make the inventory of the vulnerabilities in the study area. This is the human, animal, material and socioeconomic vulnerability. The assessment shows that the human vulnerability includes the population that is made up of Men (74), Women (101) and children (665). The animal vulnerability comprises the cattle that are constituted of sheep (200), goats (350) and domestic fouls (300). The material vulnerability includes houses and equipment, farms, cars motorbikes, bicycles and etc… The socioeconomic vulnerability is attributed to the level of the weight of the history.....

|Title||:||Auriferous, uraniferous and REEs mineralized marl of Middle Um Bogma Formation, Southwestern Sinai, Egypt|
|Authors||:||Abd Elhadi A. Abbas|
Abstract: Um Bogma Formation is considered the most important Formation in the Um Bogma area due to its content from uranium, Mn-Fe ore deposits and copper mineralization. The middle member of Um Bogma Formation consists mainly of marland clay with some intercalated shale. The eU/eTh values of the investigated marlsuggesting that these rocks are considered as productive uraniferous rocks and sites ofdeposition, especially at TaletSelem and Allouga. TaletSelem, Abu Thour, Allouga and Abu Zarab localities clarified that the mineralassociation are mainly represented by autonite, cerianite, pyrite, corandite, iron oxidesand clays-bearing REEs and bastanesite......

Abstract: Allouga area is located in the southwestern part of Sinai Peninsula. It represents one of the more significant economic and uranium mineralized area. It is located within low basin that has been formed from the normal faults of Wadi Nasib on the east and Wadi Baba on the west and most of the high radioactive anomalies recorded in the sediments of Um Bogma Formation within this basin.The Lower Carboniferous Um Bogma Formation is the main rock unitsconstituting the face wall of the Allouga quarry. The wall show very high radioactivity with eU-contents reach 3000 ppm. Sklodowskite and carnotiterepresents the main uranium minerals detected in the face wall of thequarry withanomalous contents of gold.The gold content reaches 1.78, 1.74, 2.02, 1.6, 1.78 and 1.8 ppm in.....

|Title||:||Palynostratigraphy of Well Z, OPL 310, Offshore Dahomey Basin, South-Western Nigeria|
|Authors||:||Anthonia NwanezeAsadu || Johnson Favour Nkem|
Abstract: Background: Palynological studies in Nigeria are largely confined to the propitious Tertiary Niger Delta following the discovery of hydrocarbon in the basin since the late 1950s but the quest for more discovery of hydrocarbon has led to the extension of exploration to adjacent Cretaceous basins in Nigeria. The success of a drilling project depends largely on the accuracy of the exploration process where palynology finds its practical uses. Palynological monitoring through the analysis of ditch cuttings rock samples for age determination and paleoenvironmental interpretations are important tools in stratigraphic correlation aspects of the exploration business.......
