[meteorite-list] New Arizona Find....

[Matson, Robert]

Hi Bill,

I had to dig through my old e-mails to remind myself what my
"guess" was:

"... hard to guess from a single photo -- almost certainly an H-
or an L-chondrite.  Doesn't look unequilibrated, but it doesn't
look completely equilibrated either.  My best guess would be H5
or L5, though the petrologic grade could be 4 or (less likely) 6.
Weathering grade probably W2 or W3 -- the metal flecks look
pretty good.  Don't see evidence of high shock, so S3 or less."

I guess when you're as non-commital as I was, it's easy to guess
correctly.  ;-)  --Rob

Hello List,

I am very happy to announce that the chondrite I found in January is now 
classified by Lora Bleacher at ASU. I do not have all the information yet, 
but it looks to be an
L5, S1, W3

If some of you remember your guesses just by looking were right on the 
money!

This sure is exciting stuff for someone fairly new to this fascinating world

of meteorites! So far there is about 870 grams with a 465 gram main mass.

Cheers, Bill
