Meteoritical Bulletin: Oxygen Isotope Plots

Oxygen isotope composition of enstatite chondrites and aubrites (SNCs shown for comparison). Data for Enstatite chondrites and aubrites from Newton et al. (2000). Data for Martian meteorites (SNCs) from Franchi et al. (1999) and compiled from laser fluorination analyses in the Meteoritical Bulletin. TFL: terrestrial fractionation line.
