Depleted mantle (DM)—MORB source

 3.2 ± 0.5 2.5 15600 Workman and Hart [66]
 4.7 ± 30% 2.9 12800 Salters and Stracke [67]

Model of Javoy et al. [64] is constructed following Javoy's recipe as described in [69]. *Calculation of radiogenic power for DM estimates assumes that the entire mantle has DM composition.
