Figure F8. Ba vs. Zr/Ba plot used as a proxy to discriminate Indian from Pacific mantle domains during Leg 187. Data fields are from Christie, Pedersen, Miller, et al. (2001). Data points are Leg 187 samples coded to indicate their mantle domain type as determined from their Pb isotope compositions. Points labeled "Mixed I/P" are IMM samples from sites that recovered both PMM and IMM samples. TPMM (transitional Pacific MORB mantle) field was defined during Leg 187 using onboard data. We no longer use this term. TMM = transitional MORB mantle.
