Abstract

Seafloor hydrothermal fluids transport metals from the crust to the ocean where they can form marine mineral deposits. This project uses unique fluid and mineral samples from the Juan de Fuca Ridge acquired in collaboration with Ocean Networks Canada. The investigators will carry out cutting edge analyses on these samples to better understand how the fluids form mineral deposits on the seafloor. Laboratory…
