The Manglai uranium deposit is located in the Tabei Sag within the Manit Depression, centrally positioned in the eastern Erlian Basin at the core of an ancient valley uranium metallogenic belt. This study analyzed the geochemical properties of 22 clastic and mudstone samples from the Lower Cretaceous Saihan Formation in the Manglai deposit to assess its tectonic setting, provenance direction, redox conditions, and paleoclimatic environment. Key findings reveal that (1) The primary sediment source of the Saihan Formation in the Manglai deposit consists of felsic igneous rocks, situated mainly in a passive continental margin setting.

- The Chepaizi Uplift in northwestern China is a key area for exploring uranium resources, particularly in the newly identified Neogene Shawan Formation.
- This study employs advanced techniques like scanning electron microscopy and X-ray diffraction to analyze uranium minerals and understand their geochemical properties.
- The research reveals that uranium mineralization in the Shawan Formation occurred in two stages, influenced by a dry climate and processes involving lateral migration of oxygenated waters followed by hydrocarbons affecting mineral deposits.
