Full textRoll front ore U-ore deposits in the Chu-Sarysu basin (Kazakhstan) occur in paleogene, continental silicoclastic formations. Sedimentary sequences include unconsolidated arkosic sands and clay lenses, formed by detrital minerals issued from granites and calkalcaline volcanites but also from paleozoïc series from Karatau. All formations are characterized by a fine grain clay fraction dominated by smectites, associated with palygorskite which could be the result of alternated humid and dry periods. All series underwent a rather shallow burial which is indicated by the immature feature of the organic matter, the presence of newly formed unaltered smectites, and the presence of pyrite framboïds which are formed by bacterial sulphate reduction, indicated by the wide range of delta34S of pyrites. Sands are locally cemented by calcite which precipitated from meteoric fluids at low temperature. U-ores are spatially and genetically related to sulphides and organic matter, especially in levee facies at the top of the sedimentary sequence and in association with organic macro-clasts disseminated within the sand channels. Phospho-coffinites occur latter on. These deposits show similarities with those of Wyoming but differ by the size of the roll fronts front redox, the heterogeneity of the U-ores at small scale, and a probable significant pre-concentration associated with organic matter

Full textThe Arlit U-deposits (Niger), situated in the eastern part of the Tim Mersoï Basin, less tan 50 km from the Air mountains (SE of the Hoggar), are hosted in reduced carboniferous sandstones. U-deposits are low to medium grade concentration, tabular-type, geographically controlled near major faults in the sedimentary cover. The tectonic history of the Tim Mersoï Basin is closely linked to the geodynamical context of Western Africa, since Palaeozoic to Tertiary times, and to the rejuvenation of panafrican major lineaments in the basement. This study confirm the role played by the upper Carboniferous syn-sedimentary tectonics on the sanstones channels architecture. Reduced sandstones channels are favourable zones where concentrate U-ore deposits. Compression that principally occurred from upper Cretaceous, induced the rejuventation of major faults, and conferred at the Tim Mersoï bain its general morphology. During this NW-SE compressionnal event, brittle shear zones had been created in the sedimentary cover, along the NS and almost N30° major faults (sinistral strike-slip motion). We have shown that this brittle fault zones affecting the sedimentary cover, and notably the NS Arlit-In Azawa fault, were the locus of important fluid circulations during the upper Cretaceous event. The Arlit economic U-déposits are located at the intersection between NS/NNE-SSW major brittle faults and sedimentary reduced trapps (sandstones channels)

Full textThe mineralogy and the geochemistry of the Mesoproterozoic (Riphean) Pasha-Ladoga volcanic - sedimentary intracontinental clastic basin (Russian Karelia), associated uranium mineralization and underlying basement lithologies have been characterized and compared with those of highly mineralized districts having similar age and lithologic associations. The clastic sediments appear much more immature than highly mineralized basins of the Athabasca (Canada) and Kombolgie (Northern Australia). However, large-scale fluid circulation has been evidenced in the Archean to Paleoproterozoic metamorphic rocks and Mesoproterozoic rapakivi granites of the basement and in the overlying clastic sediments of the Pasha - Ladoga area, where the Karku unconformity related uranium deposit has been discovered. These fluid circulations are related to zircon alteration and to a lesser degree to monazite at the regional scale and essentially with a Fe-chlorite and carbonate alteration assemblage produced in the mineralized districts

Full textMadagascar has been isolated from Gondwana during the Mesozoic: she separated from the african continent, ca. 180 Ma, and from the indian subcontinent, ca 150 Ma. Since then,biological evolution followed its own rythm, what Philibert COMMERSON had yet foreseen in 1771, writing that Madagascar was the "laboratory of nature" and that "Madagascar was the true land of promise for naturalists". After almost two hundred years of paleontological researches, it is time for a mapped balance sheet of Madagascar : it is the subject of this thesis. The literature on Madagascar is extremely abundant, and we brought together more than 2000 publications, printed between 1829 and 2014, in relation to the paleontology of the Island. They allowed to identify nearly 3500 fossil species, 3% of Plants (104 taxa), 89% of "Invertebrates" (231 Foraminifera, 183 Cnidarians, 14 Bryozoans, 56 Brachiopods, 6 Annelids, 392 Bivalves, 206 Gasteropods, 1746 Cephalopods, 129 Crustaceans, 60 terrestrial Arthropods and 85 Echinoderms) and 8% of Vertebrates (76 "Fishes", 7 Amphibians, 29 "Reptiles", 24 non avian Archosauromorphs, 52 Birds and 82 Mammals). These taxa are distributed in over 400 paleontological sites from the upper Paleozoïc (Permian) to the Quaternary (Holocen), distributed as follows : twenty Permian sites, 24 Triassic, over 110 Jurassic, over 130 Cretaceous, 16 Tertiary et 42 Quaternary sites. Some taxonomic groups are over-represented (eg ammonites), while others should promise new discoveries (archosaurs, mammals!...). The periods themselves have a different focus (Mesozoic vs. Cenozoic) and in the same vein, the paleontological sites are unevenly distributed in the territory (the Northwest is the most explored). The research potential is still very high. Fossils and paleontological sites are placed in a map database with comments. Thus we have achieved, at least we hope, an useful basic tool for scientists, also a "global" book for teachers and naturalists, and a support to reflection and decision for Madagascar administrators and politicians at both regional and national levels
