Scientist

Jürgen Koepke is professor at the Institute for Mineralogy at the Leibniz University Hannover. His main research themes are petrology, geochemistry and geodynamics of mid-ocean ridges. His favourite approach is to combine investigations on natural rocks from the oceanic crust recovered by research vessels or sampled in ophiolites with experimental simulations in internally heated pressure vessels. He published 78 peer-reviewed articles and was Project or Co-Project Leader of 28 Research projects funded by Deutsche Forschungsgemeinschaft (DFG). He is Program coordinator for the BSc and MSc program “Earth Sciences” at the Leibniz University of Hannover.

Lab

The Institute for Mineralogy (more than 50 professors, scientists, engineers, postdocs and PhD students) is embedded in the Earth Sciences at the Leibniz University Hannover and GeoCenter Hannover (Federal Institute for Geosciences and Natural Resources, Leibniz Institute for Applied Geophysics). Research topics are experimental geochemistry, isotope geochemistry and crystallography. It has a leading role in several fundamental international (IODP, ICDP) and in national research programs (DFG-SPP’s, DFG-Research Units; DFG “Normalverfahren”).

The Institute for Mineralogy hosts an experimental lab for simulation of magmatic processes [16 cold seal pressure vessels, 4 internally heated pressure vessels (up to 1250°C, 700 MPa) with special equipment (large volume sample holder, high temperature furnace (up to 1500°C, 700 MPa), rapid quench apparatus, Shaw membrane to control fO2]. EPMA, Laser-ablation system coupled to MC-ICP-MS Neptune (Fa. Thermo Scientific).
