Metal Isotope Group
The Metal Isotope Group (MIG) explores the source of metals, and their biogeochemical pathways and interactions between the geosphere and biosphere.
Our primary research focus is on stable and radiogenic isotope systems of selected metals, and their application to solve problems relevant to earth system evolution studies, geochronology, metallogenesis and environmental issues.
Specifically, we are interested in radiogenic isotope systems of heavy metals (Nd, Pb), and stable isotope systems of alkaline earth metals (Ca, Sr, Mg) and redox-sensitive elements (Cr, Cu, Zn).
The MIG group also investigates novel analytical approaches such as collision cell mass spectrometry. We use this for in-situ dating of selected low-temperature minerals such as glauconite and illite, based on laser-ablation analysis of Rb-Sr and K-Ca isotope systems via plasma mass spectrometry.
