Large Igneous Provinces (LIPs) and Anoxia Events in “The Boring Billion”
Geophysical Monograph Series, Page 449-486., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Control of tectonic uplift and denudation on uranium mineralization in the eastern Junggar Basin
Meitan xuebao, 2023 There is a close dynamic coupling relationship between tectonic and mineralization. Long-term research and observation have found that the formation and location of sandstone-type uranium deposits are obviously controlled by the formation of target layer

Column bioleaching of sandstone type uranium ore deposit
Pacific International Journal, 2019 Column bioleaching has been performed on sandstone-type uranium ore. The column is initially leached with H2SO4 to make the environment acidic and feasible for Thiobacillus ferroxidase bacteria growth. The column later injected with acid solution containing 6g/L H2SO4, iron source 1.5g/L (Fe3+ 0.75g/L, Fe2+ 0.75g/L) and bacteria.
