Extended Data Fig. 1: Cr in garnet and olivine Fo distribution from compiled literature with model results.
From: Deep, ultra-hot-melting residues as cradles of mantle diamond
Histograms of: Cr concentrations in global cratonic peridotite garnet and garnet DIs (a)18,37,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100,101,102,103,104,105,106,107,108,109,110; forsterite component in cratonic peridotite olivine and olivine DIs (b)8,24; garnet Cr2O3 concentrations in incremental melt model residues and batch KR4003 melt model residues during melting (c); garnet Cr2O3 over the melting interval of hybrid compositions (d). Note that DI versus peridotite distinction in a and b is more pronounced on a craton-by-craton basis than in the global database.
