Fig. 2: A plot of δ66Zn against the Mg/Zn ratio.
From: Impact-induced sublimation drives volatile depletion in carbonaceous meteorites

The ranges for various sub-groups of carbonaceous chondrites are after reference13,14. The colored arrows indicate the anticipated trends: one showing an increase in δ66Zn values due to evaporation, and the other showing a decrease in δ66Zn values resulting from incomplete condensation or sulfide separation.
