Spot 1 is a clear non fluorescent crystal of calcite
Plane polarized image of the section. Crystal labeled 2 is
forsterite, crystal 3 is magano calcite or dolomite.
The opaque crystals on this image are hausmanite, manganese oxide.
Plane polarized view. Crystal 6 is forsterite, crystal 7 is dolomite or
Crossed polars view.
Spot 8 is a fluorescent crystal of dolomite or mangano calcite. The
Raman spectrum is noisy due to the high fluorescence.
Reflection image of the fluorescent image above.
Spectra in darker region 8 has been compared with lighter area 9. The
spectra are similar, they indicate the presence of calcite or dolomite.
View of the same spots 8 and 9 in plane polarized
transmission with spectrum.
Other section of another mineral of the same location. This section
contains much more opaque crystals type 1 (hausmanite) and less crystal
2 (forsterite). The fluorescent mangano calcite or dolomite (spot 2) is
ubiquitous in this rock.

meteorites, a forsterite macro crystal already analyzed and the crystal
which appears in spot 6 above.
