Abstract

Determining the past record of chemical weathering is essential for understanding changes in climate and atmospheric CO2, such as those that occur throughout the Cenozoic (the last 65 my). Many natural radiogenic isotopes in seawater are sensitive to variations in chemical weathering, but taken alone cannot distinguish such changes from those caused by variations in erosional source (such as composition, geographical location or ocean circulation). However, comparison of isotope systems with different sources and different behaviour in seawater can resolve such effects, and the relationship between weathering and climate change can be examined on both long and short timescales.
