Upper panel: difference between the solar photospheric and bulk abundances for CI (blue circles), CM (red triangles), and CO (green stars) chondrites as measured by Bland et al. (2005). CM and CO chondrites show increasing fractionation compared to the Sun, especially for the volatile elements. Lower panel: same, but for the fine-grained matrix of chondrites. Surprisingly, the solar abundances more closely resemble the CM matrix than the CI equivalent, which shows a trend with condensation temperature. As explained in the text, for the bulk comparison Mg has been used as the reference element to connect the meteoritic and photospheric abundance scales since the Si abundances are not provided by Bland et al. (2005) for non-CI chondrite classes, which introduces a 0.02 dex offset. For the matrix compositions, the usual reference element Si has been used.
