Fig. 7. Relationships between the oxygen-isotope composition of olivine rims and cores, and the major-element composition of olivine rims.

Fig. 7

a Average olivine rim δ18O versus average olivine core δ18O in the kimberlites (and lamproites) from this study. Error bars are one SD of the mean. The blue line is the linear regression through the data points (excluding the Notre Dâme du Nord outlier). b Covariation diagram showing a broad direct correlation between δ18O and Mg# in olivine rims from the examined samples. Error bars indicate the 2σ of each analysis.
