Hi,
Having recently got a nice 0.376g slice of Dag 400, I have been looking
around the net for any research papers on it, this got me wondering if
anyone knows why the total known weight of each of the lunar falls is so
low? Is there some physical process that determines the maximum size a
Hello list,
has anyone an idea, which of the finds paired with
NWA1109 are classified as howardites?
NWA1109 is listed in the Bulletin as polymict
eucrite.
Some sell it as howardite, some as howardite or
eucrite, some as eucrite.
Thanks!Martin

at what point does a polymict eucrite become a howardite? grain size? melt?etc.??? will the REAL howardite please standup? what ARE the definitive criteria of howardite?

Harlan,
Polymict Eucrite's contain less than 10% diogenite clasts (this is man
made value to discriminate between Polymict Eucrites and Howardites)
Howardites also show more of an even distribution of eucritic and
diogenitic inclusions. Polymict Eucrites often contain pyroxene zones
within the
Hi Martin and List,
NWA1109 is definitely a eucrite as it has no
diogenite component. We stated this several times and posted publicly to
the List so if somebody is still selling it as a Howardite than they are
ignoring the scientists who studied it.
All the best,

Adam,
I have a question along the same lines related to NWA 1648. Could you summarize the
differences between a polymict diogenite (like NWA 1648) and howardites? Does a
polymict diogenite have more (or just more varied) diogenite in them than the typical
howardite?
I just got a thin section
Here's a quote from Mittlefehldt's article in the 1998 Planetary
Materials volume:
Howardites have long been known to be polymict breccias (Wahl
1952). More recently, numerous polymict breccias with bulk
compositions like those of eucrites have been recovered from Antarctica,
leading to
Dear John and List,
In simple terms, NWA 1648 was voted in as a polymict Diogenite becuase it is
mostly composed of orthopyroxene and the ratios indicated that several
Diogenitic parent rocks were sampled.
All the best,
Adam

Thanx Adam...NWA 1648 is a very nice meteorite. Like I said, it(nwa 1648) does not
have the look of a eucrite in thin section which would also suggest it is not close to
a typical transitional Howardite of 10 to 20% diogenite...as I understand things {ie.
limited knowledge for sure :) }

Just a note to let you know we have dozens of great auctions ending tonight.
We normally do not market complete individuals so this represents a great
opportunity to pick up some awesome examples. Among the specimens are
several items from our personal collection including some

I was wondering, once again, if anybody would seriously be interested in purchasing a
half-slice of the Worden, MI garage/car smasher. It is a very nice 17.3 gram
part-slice with with specks of red car paint on the top edge of it. This specimen
