Hi L.A., Listees,
Just the white powdery "CAI" material which represents a small fraction
of Allende is the old snuff ...

primitive vigarano is. As Jeff mentioned that is another matter entirely.
Second there are different methods for determining age.

Has any SEMARKONA [Indian fall of 1940, type LL3.0 (S2)] ever been distributed
to private collectors??? I very much doubt so. One of
the "next best" primitive meteorites from Jeff´s first category,

There are two meanings to the word "primitive" that are in common use
among researchers:
1) It means that the meteorite was relatively unaffected by secondary
processes that occurred on asteroids, including thermal metamorphism,
melting, shock effects, and aqueous alteration. These meteorites

Dear Listees~
I was wondering if anyone knows what the oldest (as in
most primitive) meteorite is? I was thinking it was
Allende, b/c it is believed to be of extra-solar

our own solar system?
Thanks
