Meteoritical Bulletin: Oxygen Isotope Plots

Oxygen isotope composition of Martian meteorites. Data for Martian meteorites from Franchi et al. (1999) and compiled from laser fluorination analyses in the Meteoritical Bulletin. MFL: Martian fractionation line of Franchi et al. (1999), TFL: terrestrial fractionation line.Δ¹⁷O calculated as: Δ¹⁷O = δ¹⁷O – 0.52δ¹⁸O.
