I guess that this should now be "Crystyl" clear to everyone... :)

Mike and All:
Even poor old L6's can have their 15 minutes of fame! This one has
high pressure minerals: "dark blue ringwoodite and green wadsleyite".
How cool (or should I say hot and shocked?) is that?

Hi Laurence and List,
Aaaaah, the nebulous picture becomes more clear. Science works in
mysterious ways.
It must be interesting (and fun) to have access to an institutional
collection. One could sift through the numerous specimens looking for
traits that stand out and/or features of interest. I wonder what first
caught her eye about this old Saharan OC. I wish Ms. Crystyl the best
of luck on her research and I hope we see her name more often in the
Bulletin. :)
Thanks for the explanation Laurence. :)
Best regards,
MikeG

Crystyl is a grad student in the School of Earth and Space Exploration
at
ASU. She is studying shock phases in meteorites, and by chance Sah 00293
has
something very interesting in it (you can look up her LPSC abstract
which
will be online in a few weeks). In order for her LPSC abstract to be
accepted, she had to first classify and then get the meteorite accepted
by
the NomCom.

Hi Bulletin Watchers,
There is one new approval. I find it curious. It is an old Sahara OC
found by Mr. Labenne fifteen years ago (2000). Crystylynda Fudge was
the classifier. I have never heard this name before. I am just curious
why this meteorite suddenly appeared out of obscurity to be approved
today.
Best regards and Happy Huntings,
MikeG

Bulletin write-up :
Sahara 00293
(Sahara)
Found: 2000
Classification: Ordinary chondrite (L6)
History: Reportedly collected in the same location as Sahara 98222.
Physical characteristics: Chondrules largely integrated into matrix,
difficult to discern in cut section. Abundant shock-induced melt veins
and pockets.
Petrography: Fine-grained recrystallized plagioclase throughout
matrix, some grains up to 200 ?m. Abundant metal sulfides and troilite
with trace native Cu. Evidence of minor planar deformation features in
olivine. Ubiquitous opaque shock melt veins and associated dark blue
ringwoodite and green wadsleyite.
Geochemistry: (C. Fudge, ASU) EPMA: Fa24.8?0.1 FeO/MnO: 48.8?1.6 n=11;
