Change title:




Oxygen isotope composition of HEDs and angrites. Data for angrites and HEDs from Greenwood et al. (2005). EFL: eucrite fractionation line (Greenwood et al., 2005), AFL: angrite fractionation line (Greenwood et al., 2005), TFL: terrestrial fractionation line. B: Bholghati matrix, P: Pasamonte. Δ17O is linearized using the format of Miller (2002): Δ17O = 1000 ln (1+ (δ17O/1000)) – λ1000 ln (1+ ( δ18O/1000)) where λ = 0.5247.
