Assessing the role of climate on uranium and lithium isotope behaviour in rivers draining a basaltic terrain

Abstract:

This study presents uranium (U) and lithium (Li) isotope and major and trace element data for the dissolved load, suspended particles and bedload from rivers draining dominantly basaltic catchments on the island of Sao Miguel in the Azores Archipelago. Uranium activity ratios are at secular equilibrium in the bedload, but are higher for suspended material, suggesting sorption of uranium from the solution onto particle surfaces. The (234U/238U) of the riverine dissolved phase varies between 1....
