Fig. 4: Late Neoproterozoic to early Paleozoic δ⁹⁸Mo records of global siliciclastic rocks.

The black solid line represents a “best estimate” of coeval seawater δ⁹⁸Mo evolution, as constrained by δ⁹⁸Mo of marine, euxinic, and siliciclastic sedimentary rocks (data from compilation^11,20 and this study).
