... of an endoreic basin of Syria, where U is brought into the soil, remobilised and redeposited deeper in the profile. The modelling of this U cycle and the fit with the observed ( 230 Th/ 238 U) variations with depth constrain the residence time of U in the profile and gives a current erosion rate of 10–20 mm/ka...

... based on normalized boron concentrations (B/Ga) and isotopic compositions (δ 11 B) of bulk shale. We analyzed the Stark Shale Member of the Missourian Stage Dennis Limestone cyclothem in the Charleston core (CC) from the Illinois Basin (eastward, more proximal) and the Iowa Riverton core (IRC) from...

... Basin, Canada ( Millot et al., 2010 ). Li isotope ratios (δ 7 Li) vary widely between 7.6‰ and 34.7‰ (Table DR1 in the Data Repository; Fig. 1A ). In general, rivers from the west of the island have lower δ 7 Li than the eastern rivers, and overall there is a negative trend between [Li] and δ 7 Li...

..., Great Whale, La Grande, and Nelson rivers were analyzed for dissolved uranium concentration [U] and activity ratio ( 234 U/ 238 U). Field surveys conducted during baseflow and snowmelt in six other rivers of the HJUB basin provided complementary data. It is estimated that altogether, the studied rivers...
