Scientific paper

Carbon concentrations in a 4.2 x 4.2 mm area of the Allende meteorite were mapped with the C-12(d,p)C-13 nuclear method. The x,y resolution perpendicular to the deuteron beam was 65 microns; the depth resolution was 0.6 micron. The matrix of the meteorite contains about 1 wt pct carbon, which is uniformly distributed at the 65-micron level of resolution. The matrix contains most, perhaps close to all, C of this meteorite. The coarse-grained constituents, such as chondrules, show a very strong enhancement of C in the depth range 2 to about 0 micron; the matrix does not show this enhancement. The enhancement may be due to contamination of the coarse-grained areas or else to migration of C in solid solution from the interiors of comparatively large crystals to their freshly polished surfaces.
