Hi Tom and List,

Color:

The pictures I've taken of my thin section fully support Tom's description
of the NWA 969 (LL6/7*). It is very colorful: the pyroxenes and olivines
come along in all shades of blue, purplish red, brown, orange, yellow, gray,
and olive(-green) when viewed in cross-polarized light.

Clarity:

Usually I have to enhance the clarity of the JPEGs a little with the help
of my Adobe Photo Shop computer program but in this case I had to reduce
both the brightness and the contrast of the pictures.

*According to the correction in the MetBull and I agree with this correction
because my TS actually shows a relict barred olivine chondrule that has been
torn to pieces by some process but is still recognizable and it must have been
pretty large!

Interest:

Tom, I would surely love to see your micrograph, especially
if it shows those infamous "trains of f l u i d inclusions".

Remember the nickname the Hup?s gave this meteorite?
They dubbed it the "meteorite with bottled water".


Best wishes,

Bernd
