Sedimentology and sediment geochemistry

The interests of our research group are centered on large-scale processes during Earth's history, which have relevance to present-day environmental change. They include research on paleo-environmental change in carbonate platforms (present-day analogue: coral reefs), phosphorite deposits (carrying the essential nutrient phosphate), organic-carbon-rich deposits (sinks for atmospheric CO2), weathering processes on the continent (as a source for essential biophile elements), major extinction events, trace-metal contaminations, and paleoclimatic reconstructions.
