The diagenesis or transformation of silicate minerals plays a major role in the regulation of the Earth´s carbon cycle and climate system. Chemical weathering and reverse weathering involving silicate minerals in terrestrial environments are likely the most important processes controlling the long-term CO2 concentration in the atmosphere and thereby, green house forcing. It is much less understood whether similar processes occur in marine environments and what is the scale at which such processes occur, locally and globally. The project will involve the following activities.
- Reproduction of conditions favoring in-situ marine silicate diagenesis in the laboratory (e.g., incubating marine sediments under pressure in a seawater medium) to have a better mechanistic understanding of the processes.
- Analyses of key geochemical proxies (e.g. δ30Si and 87Sr/86Sr) from marine sediments and pore fluid samples collected at locations where in-situ marine silicate diagenesis is thought to occur.
- Development of numerical models to quantitatively describe the observations in the laboratory and field, which is essential for upscaling.
