Meteoritical Bulletin: Oxygen Isotope Plots

Oxygen isotope composition of lunar rocks and meteorites. Data for lunar samples from Wiechert et al. (2001); Spicuzza et al. (2007); Hallis et al. (2010). Data for lunar meteorite samples compiled from the Meteoritical Bulletin. Angrite data from Greenwood et al. (2005), Irving et al. (2005, 2006). Δ¹⁷O is linearized using the format of Miller (2002): Δ¹⁷O = 1000 ln (1+ (δ¹⁷O/1000)) – λ1000 ln (1+ (δ¹⁸O/1000)) where λ = 0.5247. TFL = Terrestrial Fractionation Line. AFL = angrite fractionation (Greenwood et al., 2005).
