Zinc isotope fractionation between Cr-spinel and olivine and its implications for chromite crystallization during magma differentiation
We report the first zinc isotope data (expressed as δ 66 Zn relative to the JMC-Lyon
standard) for chromian spinels (Cr-spinels) and coexisting olivines in oceanic peridotites. All …

Zinc isotopes of the Mariana and Ryukyu arc‐related lavas reveal recycling of forearc serpentinites into the subarc mantle
Mantle source heterogeneity of arc‐related magmas was traditionally thought to be
predominantly affected by slab‐derived components. However, the role of forearc …
