Seminar: From Hard Rock to Heavy Metal - how high-mass metal stable isotopes are helping us understand the Earth’s mantle

The silicate mantles of terrestrial planets constitute the vast proportion of their mass and govern the chemical and geodynamic evolution of these bodies. Understanding the physical and chemical interplay between the solid Earth’s main chemical reservoirs - mantle, crust and core - is a fascinating subject that has challenged geochemists for decades. In this talk, I will discuss how the development of a vast spectrum of high mass (> 20 amu) stable isotope systems has contributed to the field of mantle geochemistry over the last decade and the new opportunities and challenges that the application of these tracers has provided, with a particular focus on rocks formed in the first billion years of Earth’s history and modern mantle plumes.
