"I want to share a beautiful meteorite micrograph that seems to have
everything, color, clarity and interest. It is taken of NWA 969 LL7.
Please email me for a full size attachment of this image. This one
is worth checking out!"
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 Hupés gave this meteorite?
They dubbed it the "meteorite with bottled water".
Best wishes,
Bernd
