    Uranium is a silvery-gray metallic weakly radioactive chemical has the chemical symbol U and atomic number The most common isotopes in natural uranium are U (%) and U (%). All uranium isotopes present in natural uranium are radioactive and fissionable, and U is fissile (will support a neutron-mediated chain reaction). Uranium, thorium, and potassium are the. Posts about sulfide mineralization written by stevepiercey. Irish-type zinc-lead deposits represent a distinctive sub-class of the carbonate-hosted zinc-lead deposit family, having geological features and genetic models that are hybrids between sedimentary exhalative (SEDEX; also known as clastic zinc-lead deposits) and Mississippi Valley-type (MVT) deposits.

    journal article: sulfur isotopes as a clue to the genetic geochemistry of a roll-type uranium deposit. Organic carbon and reduced sulfur species (pyrite and sulfide), which are the most common products of sulfate reduction associated with organic matter, are reducing agents that are available to precipitate uranium in sedimentary rocks (Reynolds & Goldhaber ; Spirakis ).Cited by: 3.

    Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to chemical compounds large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide. Hydrogen sulfide (H 2 S) and bisulfide (SH −) are the conjugate CAS Number: Carbon source: organic compounds Do not produce oxygen Purple (and green) non-sulfur bacteria Ex. Swamps commonly have purple and green bacteria living this way utilizing decaying organic material for a carbon source, but using light as and energy source.

However, organic carbon (possibly introduced) is the energy source for sulfate-reducing bacteria. Introduction Organic carbon and sulfide sulfur are common constituents in many roll- type uranium deposits but their exact roles in ore-forming processes is not completely : Joel S.

Usually, these plots are useful to recognize nonmarine vs. marine environments or oxic vs. anoxic vs. euxinic depositional by: Abstract. Anomalous concentrations of iron sulfides found at roll fronts are believed to result from limited oxidation and mobilization of reduced sulfur species from earlier formed pyrite within the more extensively oxidized core of the roll.

Laboratory experiments and chemical theory suggest that the reactions need not be biogenic, Cited by: Sandstone uranium (U) roll-front deposits of Wyoming and Colorado (USA) are important U resources, and may provide a terrestrial source for critical accessory elements, such as selenium (Se), molybdenum (Mo), and tellurium (Te).Cited by: Although organic matter is a stronger re- ductant than hydrogen sulfide, experiments have shown that hydrogen sulfide is a more aggressive reductant (less kinetically inhibited) and in some deposits, hydrogen sulfide, derived from the reduc- tion of sulfate by organic matter may have reduced by: The existence of sulfur-oxidizing bacteria and sulfate-reducing bacteria in the deposit may have resulted in bacterial sulfate reduction to sulfide, re-oxidization of the sulfide to sulfate and subsequent reduction of the sulfate to sulfide.

Uranium sources for the Qianjiadian deposit are comparable to that of the adjacent Baixingtu deposit because they share the same ore-bearing Yaojia Formation in the Qianjiadian Sag and are just 15 km far away from each other (Bonnetti et al., b), which indicates that they are geologically by: 8.

Pyrite crystals and ore-bearing shales of the Degdekan deposit were studied by means of XPS, SEM–EDX, EPMA, and AAS. Five peaks of carbon organic forms were identified, conforming to polymer compounds containing either double bonds of carbon or alkyne groups and compounds containing C–OH and C=O bonds, as well as, probably, small amounts of S-containing compounds Author: V.

Tauson, R. Kravtsova, V. Akimov, S. Lipko, A. Spiridonov, A. Budyak, I. Vor. The Dongsheng uranium deposit is located in northern Ordos Basin, northwest China (Fig. 1a).The geology of the Ordos Basin has been reported in Di () and Cai et al.

Thus, uranium is accumulated gradually in the macerals through an organic carbon-uranium epigenization process, in respect to the maceral's chemistry.

Organic biomarkers consistent with sulfide-oxidizing bacteria were recently reported from inter-ore beds at the giant Proterozoic McArthur River Zn-Pb SEDEX deposit (Logan and Hinman, ), and a diverse microfossil assemblage is preserved in black chert nodules intimately associated with Zn-Pb mineralization (Oehler and Logan, ).
