Eric,
Though I'm not in total agreement with you, that is a good point.
What it comes down to is terrestrial age. That would settle it. For
instance, the L chondrites at Franconia are quite obviously from a more
recent event, I'm certain they are not related., the are distinctly
different in hand and look fresher, and far rarer..
Almahitta - Sita, among others, says they are not always homogeneous.
You make good points
Sincerely,

You mean all those H3-5's are paired?!? Lord.
I think people forget that there are LL's, L's and H's found from the
Gold Basin
fall. To say that a mass from a parent body large enough to have a
strewn field
of this size and TKW should be one homogeneous petro.-type is silly.
This business of trying to classify every stone as a different fall for
what
ever selfish or perverse reason along with having a personal attachment
to the
outcome of the over all conclusion is ridiculous and completely against
the
scientific method.
How many of those YDCA or what ever H3-5's have been found outside the
mapped
strewn field? And how far?

Hi All,
Just read another article in the 2013 March edition of M&PS,
"Stones from Mohave County, Arizona:
Multiple falls in the 'Franconia strewn field' "
by Melinda Hutson, et al.
There is much to digest from this 5-author paper that is 25 pages
long.
What with 14 stones being studied and 7 pairings to be described,
there is a
lot to chew on.
Here's something to chew on. According to this paper, "Much
unclassified
material that has been distributed [sold] as 'Franconia' may not be
from the
Franconia fall". The authors make a case that more than half of the
finds made
in the "Franconia area" are paired to the Buck Mountain Wash fall.
It has taken 10 years, but these findings show that I was justified
in my
belly-aching about all of the self-pairing that was occurring back
then. It
was on this very List that I was strongly criticized for this, and many
dealers
that thought they knew better defended their God-given right to name
their
stones after the Franconia meteorite that I got classified. A closer
look at
the MetBull images for Franconia shows that very few of them are from
the
Franconia fall. I offer no apologies for taking great satisfaction in
the fact
that I am now vindicated.
The paper goes on to show that every Sacramento Wash numbered
meteorite is
paired to Buck Mountain Wash, which effectively has resulted in the
demise of
the SaW DCA and hastened the formation of the Yucca DCA.
As I said, if you read this paper, there's a lot more to digest.
It's late and I'm thinking about chewing on an antacid pill.

Hi All!
Just a point of information. I just read Dr. Rubin's paper,
"Multiple melting in a four-layered barred-olivine chondrule with
compositionally heterogeneous glass from LL3.0 Semarkona"
Whew! That's a title for a paper!
While we are on the subject of melts, I thought I'd point-out
this paper.
Enjoyed reading it the first time....actually understood some
of it and will read it once again after thinking about it
for a while.
You folks might enjoy reading it when you get a chance!
Thanks Alan!!
