NASA OSIRIS-REx mission and sample analysis on Asteroid Bennu
On September 24, 2023, NASA's OSIRIS-REx mission successfully returned a capsule to Earth containing material from asteroid Bennu. This marked the first time a U.S. mission delivered pristine asteroid samples and is the largest asteroid sample return to date. These samples, among the oldest, most primitive, and pristine materials available, originate from a well-studied asteroid. They offer a unique opportunity to deepen our understanding of the formation and evolution of the solar system. In this talk, I will provide a brief overview of NASA's OSIRIS-REx mission and present our latest findings on the major and trace elemental composition, as well as the isotopes of moderately volatile elements, in Bennu samples.

Understanding Central European Volcanism: new age, chemical and petrological data, and the connection between Alpine foreland tectonics, magmatism, and hydrothermal activityThe Central European Volcanic Province (CEVP) comprises hundreds of Cretaceous to modern volcanoes of basaltic, basanitic, nephelinitic, melilititic, and evolved compositions. New data show surprising correlations between age, whole-rock composition, and mineralogy in SW German volcanics between Frankfurt, Basel and Konstanz, which record different melting episodes in a heterogeneous mantle. These are related to specific stages in Alpine foreland tectonics and even correlate with hydrothermal activity responsible e.g., for the formation of base metal deposits in the crystalline basement of the Schwarzwald. The talk will cover all these topics and present a broad overview of these exciting new results.
