Hi Jeff, Jerry, and List,

"Man! That's an incredible individual.
Everything's in such outlandish focus."

If that remark refers to NWA 3119, I whole-heartedly agree.
It's really hard to believe we are "only" looking at an LL4
chondrite. If I had to judge from the overall density and
frequency of well-developed chondrules (especially in the
seven o'clock position of Jeff's image #3), I'd probably call
it an L3.x or an LL3.x but other areas are definitely more
highly metamorphosed. Moreover, the olivine Fa-value (28.4)
and the pyroxene Fs-value (23.6) clearly place it in the
field of the LL4, LL5, LL6 chondrites.

My 0.65-gram and 1.95-gram slices of this beautiful LL4 chondrite
are from Rob Wesel. The smaller piece has chondrules sitting so
tightly packed together that there is hardly any matrix material
to be found. The larger piece is less chondrule-laden but sports
a gorgeous, large pyroxene chondrule measuring 5 mm in diameter
and close to the latter, there is one of those bull's-eye chondrules
(bleached chondrules) that seem to be fairly abundant in NWA 3119.
Jeff's images also show some of these bleached chondrules!

Pictures of my two pieces go to Jeff and to Jerry!

Cheers,

Bernd
