Fig. 5: Comparison of Sr and Nd isotopes in olivines and kimberlites.
From: Primordial neon and the deep mantle origin of kimberlites

Sr and Nd isotopes are corrected for radiogenic ingrowth using kimberlite emplacement ages (Supplementary Data 1), and measured Rb/Sr and Sm/Nd ratios (Supplementary Data 3). Straight connectors link olivine compositions to those of bulk kimberlite samples (‘bulk’) from which the olivine grains were separated. The isotopic compositions of olivine are assumed to reflect those of trapped fluid inclusions.
