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 of NWA 1648 from Jeff Rowell and it has very little, if any,
needle like plagioclase typcially seen in eucrite material. Maybe that fact alone is
telling me that it is mostly diogenite?
Thanx in advance,
John

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,

Subject: [meteorite-list] Polymict EUC
vs. HOW - NWA1109 question
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
