This overview addresses uranium ore deposition and classification, mining refining of are briefly given. The main properties primary secondary minerals reported. surficial deposits account for approximately 4% world resources, defined as young uraniferous sediments soils - Tertiary to Recent near surface. major controlling factors effect the distribution reported in details such : climate, sour...

Whereas titanosaurians represent the most diverse and cosmopolitan clade of Cretaceous sauropod dinosaurs, they remain rare components of Cretaceous African faunas. Currently recognized continental African titanosaurians include Aegyptosaurus baharijensis and Paralititan stromeri from early Upper Cretaceous deposits near Bahariya Oasis, Egypt, and Malawisaurus dixeyi and Karongasaurus gittelman...

Abstract Shale-rich reservoirs present a long-standing challenge for reservoir geologists because the clay minerals often induce large-scale heterogeneity in pore system. This work aims to understand impact of distribution and mineralogy which would enhance predictability best facies. We integrate seismic, well-log datasets investigate petrophysical characteristics clay-rich Cenomanian Clastics...

Globally, there is a rising demand for water purification. This driven by numerous factors, including economic growth, increasing population, shortage, and deterioration of quality. The current work highlights the manufacturing environmentally friendly highly efficient sorbent based on chitosan nanoparticles after successive crosslinking (using glutaraldehyde) modification through grafting 4-am...
