[meteorite-list] Soledade etch, check this out!

[Martin Altmann]

Hi Bernd and Mike,

to me it's looking just as typical IAB-iron should look alike.
It's not only looking like Odessa, it's looking like Morasko (which was an
IAB before and many can't find a reason, why it's now a IIICD) and even in a
very, very few Canyons you can find such nice cohenite wormlets parallelly
oriented to the Widmannstätter patterns.
Thus Matteos observations were not so stupid.
Cohenite and troilite eyes rimmed with schreibersite, cohenite and graphite
are most often found in Odessa (and somewhat rarer in Morasko, but this has
more often Neumann lines).

So where is the problem? Just another pretty IAB.
Martin
