Hi Listees,

After posting some photos of my oddball brecciated meteorites, several
of you emailed me to say that the meteorite resembled a weathered
lunar - specifically one of the Shisr lunars from Oman. I must admit,
that there is a strong resemblance between them. And I would be very
fortunate and happy to find an unexpected 18-gram lunar hiding in my
uNWA box. But, this meteorite has visible metal fleck in it and it
exhibits attraction to a magnet. I have always been told (and read)
than lunars are not attracted to magnets and rarely have any visible
free metal.

So, does the presence of metal and magnetic attraction rule out my
weird breccia as a lunar? If so, then it's probably some kind of L or
LL impact melt breccia like Bison. Which would still be interesting
and fun, but a little anti-climactic after the lunar speculation.

I'd like to direct this question to those folks who have handled a lot
of lunars firsthand, like Adam and Greg Hupe, or some of the
scientists on the List.

Best regards,

MikeG
