Abstract Modern river studies support the generalization that surface waters in regions undergoing extensive chemical weathering have elevated dissolved germanium/silicon (Ge/Si) ratios compared to regions with less extensive chemical weathering, thought to be the result of Ge fractionation in 2:1 clays. Temporal variations in Ge/Si observed in marine diatoms have thus been linked to past global trends in terrestrial weathering. However, this relationship has not been adequately ground-truthed… CONTINUE READING
