Abstract Uptake of uranium (U) by secondary minerals, such as carbonates and iron (Fe)-sulfides, that occur ubiquitously on Earth, may be substantial in deep anoxic environments compared to surficial settings due to different environment-specific con

Dissolved organic matter in the Fennoscandian Shield deep continental bedrock fracture waters of varying characteristics and ages carries a strong terrigenous signature, and only a small proportion of this potential energy source links to the deep bi

The deep terrestrial biosphere encompasses the life below the photosynthesis-fueled surface that perseveres in typically nutrient and energy depleted anoxic groundwaters. The composition and cycling of this vast dissolved organic matter (DOM) reservo

U-Pb isotope systems have been used to constrain the timing of formation, alteration, and oxidation of U minerals from the meta-granitic bedrock at Forsmark, eastern Sweden. Secondary ion mass spectrometry (SIMS) has been used to collect U-Pb data fr

Moraine waters and solid samples were collected at Kangerlussuaq, western Greenland, during the early autumns of 2014 and 2015. While the solid samples show only limited evidence of chemical weathering of silicates, both the moraine groundwaters and

The mobility of natural U is compared among four boreholes in a fractured granite using Ra isotopes and geochemical modelling. Rn-222/Ra-226 activity ratios (ARs) spanning an order of magnitude underline differences in reactive surface area. (Ra-224/

Elevated U concentrations, most evident in a section ∼500 mbsl, have been measured in deep Fe(II)-containing groundwater at Forsmark, eastern Sweden and have prompted detailed geochemical and isotopic investigations. The highest U contents (up to 1
