... ( Fig. 4b ). Previously, similar compositions of metasomatic garnets with inclusions of crichtonite-group minerals from the Internatsionalnaya kimberlite pipe were reported by Rezvukhin et al. ( 2018 ). Based on these data, we suggest that pyrope paragenesis in terms of associated titanate minerals...
