Figure 3-15. Element composition (normalized to silicon)
of micrometeroid residue found in the crater shown in figure 3-14.
The open squares and circles represent different electron-beam probe
runs. The elemental compositions of two types of carbonaceous
chondrite meteorites (C1 and C3), represented by solid circles and by
crosses, respectively, are shown for comparison.
