- Abstract:
- Continental weathering and erosion are amongst the primary processes responsible for the evolution of the landscape, exert a major control on the transport of material from the continents to the oceans, and on the cycles of many chemical elements, including carbon, at the Earth's surface. Chemical weathering affects climate by consuming atmospheric CO2, which in turn leads to cooler temperatures through a reduced greenhouse warming. A number of radiogenic isotopes in seawater are sensitive to changes in continental weathering and erosion. However, recent studies have shown that differences in the weathering susceptibility of minerals may have dramatic consequences for the chemical signal delivered to the oceans. Consequently, while marine radiogenic isotope records clearly preserve information on changes in weathering, their link to climate change and CO2 consumption is difficult to accurately constrain. The goal of this project is to quantify the effects of incongruent mineral weathering on the behaviour of a number of key radiogenic systems, through the study of natural and experimental systems. To apply these results to an improved understanding of the consequences of such weathering on the radiogenic isotope signal to the oceans, the effects of glaciation, and the consequences for atmospheric 002 consumption and global temperature.
