Earth's environmental history

Hallmark periods in Earth's environmental history: Neoproterozoic to Cambrian transition, Permo-Triassic


A key research topic is on the application of lithium, boron, calcium, magnesium and strontium isotopes to study deep time records of global change with focus on ocean acidification and Earth System response through continental weathering.

Active plate boundaries


Active plate boundaries: exchange between seawater, oceanic crust and continental crust


An additional focus is on transport and (re)cycling of elements at active plate margins. Mantle dynamics, plate tectonics and mass transfer are processes which have shaped our earth and are currently influencing the environment through volcanic eruptions, earth quakes, tsunamis and climate change.

Material flux in(to) the ocean

Material flux in(to) the ocean and global environmental parameters in the Quaternary


The signatures of radiogenic isotopes provide information on the continental input into the ocean. This input reflects large scale variations in weathering and rates of denudation that are controlled by orogen building, large igneous events or climatic changes like glacial and interglacial intervals.
