Study reveals zinc isotope fractionation during mid-ocean ridge basalt differentiation

Zinc (Zn) isotope systematics is a useful tool to study planetary evolution and trace carbon cycling in the Earth’s mantle. However, zinc isotope data for mid-ocean ridge basalts (MORB), the most widespread magmatic rocks on Earth, are scarce. The possible effects of MORB differentiation and mantle compositional heterogeneity on MORB Zn isotope compositions remain unclear.
