Meteoritical Bulletin: Oxygen Isotope Plots

Oxygen isotope composition of main-group pallasites and mesosiderites. Data for main-group pallasites and mesosiderites from Greenwood et al. (2006). Solid lines through data points show the mean Δ¹⁷O value for each group. Grey-shaded boxes depict the 2σ error on the mesosiderite and main-group pallasite population Δ¹⁷O and δ¹⁸O mean values. Open squares are individual mesosiderite analyses, open circles individual pallasite analyses. The dashed line labelled (1) is the eucrite fractionation line of Greenwood et al. (2005); the dashed line labelled (2) shows the range of HED values obtained by Weichert et al. (2004). 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.
