For anyone who may be interested I'm getting some pieces of a unique
stony-iron parent body in next week. I'll soon have four slices of Eagle
Station in and am currently accepting offers.
You can see pictures of them here at
www.asteroidmodels.com/meteoritesales.htm Almost all pallasites come from
the same parent body except the pyroxene pallasites and the three members of
the Eagle Station grouplet. This is also a good chance for all you type
collectors out there to fill a hole in your collection that you hardly ever

Speaking of "unique parent bodies", what is the
general consensus on the number of parent bodies to
account for all the various stony-irons? Is this new
classification scheme developing because of new

Hello Dave and Mike,

I think it's also practical to rethink the terms
chondrite and achondrite as useful classification
parameters. We now have the achondrite acapulcoite NWA
725 (Tissemoumine) which has distinct chondrules,
along with relict chondrules in Monument Draw. And
there are
a few carbonaceous chondrites that have experienced
complete aqueous alteration of their chondrules to the
point of obliteration (an aqueous achondrite?). And
what about chondrites that have not experienced
igneous conditions, but instead have been totally
recrystallized by the heat of impact, sometimes
classified as petrologic grade 7 (an impact

But just as we can choose to use the relatively
general term mesosiderite, it's really a matter of how
detailed the information is that you wish to convey. A
simple division into stones, irons, and stony-irons
may suffice for some situations, but even the option
split the classification scheme into unique parent
bodies is becoming more possible each year.
