Murray Lake seems to be a special case. From what i read, a protective crust
formed on the outside of the meteorite as a result of weathering.. When cut has
it been found to be more stable than any other iron meteorite? Also, i've read
that Seymchan and the Springwater pallasits, are quite stable too. My Brenhams
are already rusting and the olivines falling out..

Melanie and Listers,

That's a great meteorite you have there. Another meteorite you might want to
check into is Murray Lake for resistant to oxidation. Its the oldest known and
intact meteorite that has been recovered. The age of the meteorite is around 120
million years old. That's sometime it has spent on Earth.

Hi list,
Which meteorites would you say are known to be the least susceptible moister and

oxidation? I have two slices of NWA 5234 melted eucrite (one of the prettiest of

meteorites imo) and the material seems very stable - i've had them for over a
year, handled them quite a bit and they show no signs of rusting.. *knocks on
wood*


So I wager it'd be some of the achondrites that have the least amounts of iron
and other components reactive to oxygen... which meteorites are they
(name/designation and class)?
