The relationship between riverine lithium isotope composition and silicate weathering rates in Iceland

Abstract:

This study presents lithium isotope and elemental data for the dissolved phase and suspended and bedload sediments of the major Icelandic rivers. For the dissolved phase, δ7Li values range between 10.1‰ and 23.8‰, while river sediments display lower and much more homogeneous values (δ7Li = 3.1‰-4.8‰), close to the composition of unweathered Mid-Ocean Ridge Basalt (MORB). High δ7Li values are associated with high K/Li, Na/Li and Mg/Li ratios, in waters draining mainly old and weathered basalt ...
