Heavy copper isotopes in arc‐related lavas from cold subduction zones uncover a sub‐arc mantle metasomatized by serpentinite‐derived sulfate‐rich fluids
Serpentinite dehydration during subduction releases fluids into the sub‐arc mantle, yet the
oxidizing capability of these fluids remains controversial. Here, redox‐sensitive Cu isotopes …
