Hi Elton & all,
In my experience... you just never know what something might come back as.
Just think of the huge NWA EL3 find and all the classifications that went
through. There is hardly a chondrule to be seen in that meteorite... yet
it's a type-3!
There are a couple of others that I've had a 'double take' on and thought...
is that right?
This one for example was classified as an H6!!!!!!!! I have several pieces
of this meteorite and some have even more chondrules.

And then poor old NWA 2622... didn't quite make the type-3 club yet it's
even nicer than some of my other type-3's.

But the meteoriticists know their stuff and everything is classified the way
it is for a reason!
Cheers,
Jeff

Subject: Re: [meteorite-list] H4? the terdaght meteorite fall
Thank You Ben--I don't disagree. Apparently it has already been resold but
my point was how does one "estimate" that the meteorite was an H4 if there
were no chondrules visible? It isn't impossible, I guess, but on the face
value of the statement is hard for me to visualize how an H4 can "look like"
an H6 but be an H4. I was trying to establish the basis for the claim of H4
vs H6.
I realize it is not necessarily the quantity of chondrules over the state of
the chondrules metamorphasis that determines petrology. I know that in all
the H4s in my possession I can easily distinguish chondrules. Apparently
there are enough informed members that there is something legitimate to the
estimate.
Perhaps we've an H4 with a major void of chondrules within a portion of the
matrix and that is very noteworthy if it proves out.
