New insights on Earth’s formation and differentiation processes from in situ analyses of halogens (F, Cl, Br and I) in meteorites and mantle samples

Project description

Tracing halogens in meteorites offers new insight into Earth formation

The physical and chemical evolution of Earth as well the development of life on its surface relies on volatile elements just like halogens. Fundamental questions regarding how and when the Earth acquired its volatile elements and how they are currently distributed between its geochemical reservoirs still remain unsolved. The EU-funded HAMA project will seek to shed further insight into the geochemistry of halogens by measuring the fluorine, chlorine, bromine and iodine elements in a diverse group of primitive meteorites. These meteorites may have been some of the building blocks from which Earth formed. Project research will reveal how halogens subducted back into the mantle behave, and how they influence magma chemistry and volcanism.
