Change title:




Oxygen isotope composition of differentiated achondrites. Data for angrites and HEDs from Greenwood et al. (2005). Data for Martian meteorites from Franchi et al. (1999). EFL: eucrite fractionation line (Greenwood et al., 2005), AFL: angrite fractionation line (Greenwood et al., 2005), MFL: Martian fractionation line (Franchi et al., 1999), TFL: terrestrial fractionation line. M: average value of Martian meteorite analyses from Franchi et al. (1999). E: bulk terrestrial mantle (Mattey et al., 1994). Open squares: HEDs, open triangles: angrites, open circles: Martian meteorites. Δ17O is linearized using the format of Miller (2002): Δ17O = 1000 ln (1+ (δ17O/1000)) – λ1000 ln (1+ ( δ18O/1000)) where λ = 0.5247.
