Spot 1 is a dark crystal with high refraction
index. Raman spectrum above indicates Eckermanite.
Spot 2 is a violet fluorite crystal.
Crystal 3 is Nepheline ( low refraction index as
seen on single polarized refection image)
On the top of this image, the very low index
fluorite can be seen.
The yellow crystal (spot 4) is probably the Rosenbuschite. (or Rinkite).
About the same spectrum is obtained on
Spot 5 has a spectrum not yet fully understood: it has the same Raman
spectrum as muscovite with 2 extra peaks marked in red.
The green crystal 6 is Aegirine, see spectrum
Crystal 8 of low refraction index is microcline.
Crystal 9 is green Aegirine as can be seen on a
Spectrum of crystal 10 could be a mixture of 2
minerals. On the single polarized reflection image, this material seems
to be altered. One of the mineral could be a mica the other could be
analcime both from alteration of aegirine.
Spot 11 is Nepheline
The clear crystal 12 is microcline as can also be seen
in thin section.
