Important role of seawater radiolysis of the World Ocean in the chemical evolution of the early Earth
2022, Radiation Physics and ChemistryCitation Excerpt :The presence of hydrogen in groundwater and the correlation of its content with the amount of helium and radon arising from the decay of uranium and thorium were explained and evaluated from the point of view of water radiolysis (Vovk, 1982, 1987a, 1987b). This approach is consistent with the observation of H2-rich fluid inclusions in a natural fission reactor at Oklo, Gabon (Savary and Pagel, 1997). Computer simulation of the radiolysis of seawater caused by the decay of radioactive 40K indicated the important role of this process in the oxygenation of the atmosphere (Draganić et al., 1991; Draganic, 2005).
Dominant products and reactions during organic matter radiolysis: Implications for hydrocarbon generation of uranium-rich shales
2022, Marine and Petroleum GeologyMineralogical and geochemical evidence for biogenic uranium mineralization in northern Songliao Basin, NE China
2022, Ore Geology ReviewsCitation Excerpt :For instance, in the Daying uranium deposit located in the northern Ordos Basin, carbonaceous debris is widely distributed in the terrestrial facies sandstone in the forms of lumps and bands (Zhang et al., 2019). The role of organic matter in maintaining reducing conditions had also been reported in the natural reactors at Oklo, Gabon and uranium deposits in the Grants uranium region, New Mexico, USA (Nagy et al., 1993; Gauthiere-Lafaye et al., 1996; Spirakis, 1996; Savary and Pagel, 1997; Janeczek, 1999; Deditius et al., 2008). Besides, the clastic organic matters also provide food for the anaerobic bacteria and maintain the energy supply for bacterial metabolic processes.
