I obtained my doctoral degree in Geology (Dr. rer. nat.) from the University of Stuttgart and have mainly been working on the geology of large meteorite impact structures on Earth. Impact cratering has shaped the surface of our planet and other bodies in space ever since. Large impacts have had a major influence on the evolution of the Earth’s biosphere and the generation of economic deposits.
My work at the Lunar and Planetary Institute largely focuses on the petrographic and geochemical characterization of intensely shocked and impact-melted chondritic materials. Moreover, I curate a comprehensive collection of impactite thin-sections from a large number of terrestrial impact structures worldwide, soon to be turned into an online compendium. My previous and ongoing research includes the optical microscopic and SEM-aided petrography and geochemistry of impactites, meteorites, and shock metamorphic effects in rocks and minerals; classical field geology; the sedimentology of impact structures and materials; remote sensing; and the isotopic dating of large impact events using the 40Ar/39Ar dating technique on impact melt rocks and glasses, and U–Pb dating of impact-metamorphosed zircons. One further field of interest is volcanology. For more information and a full publication list, please visit my personal website www.suevite.com.
