good: next time you leave a 50 kg martian or lunar on the ground because
it is not magnetic and too far from your car trunk, let me know the place,
I am ready to rent an helicopter...

Which meteorites would NOT be attracted to a magnet.
Lunar and Mars meteorites to my knowledge anymore out their??

I wrote in my fisrt message: a lot of rare meteorites (angrite, HED, SNC, R
and CM chondrites, some LL and aubrites) are not attracted by a magnet.

I can add some CV. If you have some Allende: it is not magnetic (in the
sense of the magnet; with the right probe, it has a strong magnetic signal!)
