Fig. 1: Zinc isotopic compositions of mantle peridotite and several crustal reservoirs.
From: Zinc isotopic evidence for recycled carbonate in the deep mantle

The blue line marks the average δ66Zn value of the peridotitic mantle (δ66Zn = 0.16‰, ref. 27) and the vertical gray field marks the δ66Zn range of the peridotitic mantle (δ66Zn = 0.10‰~0.22‰, ref. 27). The number of samples (N), average δ66Zn values and 2 standard deviations (2 SD) are given. Reference data are shown as symbols with gray rims, and data of this study are shown as symbols with black rims. See Supplementary Information, Note 6 for data sources. MORB = Mid-Ocean Ridge Basalt.
