is a false color x-ray map of the lunar meteorite
3333, an impact breccia. Red represents aluminum,
green, magnesium, and blue, iron. This section contains
a large olivine-phyric basalt clast (left), an olivine
gabbro cumulate clast (right side), and breccia.
In this scheme, red grains are plagioclase, green
are mostly olivine and some magnesian pyroxene, and
purple to blue colors are Fe-rich pyroxene, glass,
and ilmenite. A glassy impact-melt vein with several
large vesicles cuts through the breccia on the right
side. X-ray images were taken with the JEOL
8200 electron microprobe.
