Hi Pat
How strongly is it attracted to a magnet? In my limited experience,
a carbonaceous in general would be less attracted to a magnet
I would say the magnet attracts to the meteorite in the same range L-H
chondrite.I tested Allende CV3.2, Moapa ValleyCM1,These two had less
attraction for the magnet.Dag 192 CO3, NWA801 CR2, and Lucerne Dry lake
CK4 had a attraction that was close to my meteorite.
Just by eye and heft, what is the density compared to an OC?
Carbonaceous Ch. are usually less dense than an OC
It does seem less dense than OC pieces in the same size range that I
have.

Hi Sonny,
Nice find. I second your idea about not wanting to cut it. At first
blush it does look carbonaceous. The crust does have that 'bubbly
burnt marshmallow' kind of look as I have seen on some other
carbonaceous chondrites.

Carbonaceous Ch. are usually less dense than an OC
* I would also recommend looking at it in reflected cross polarized
light. The allows you to look through the desert vanish (but not real
fusion crust) and may give a better look at the interior without
cutting.
Best Regards and Happy Hunting,

Subject: [meteorite-list] New 4.4g Cold find
Hi All,
I found a 4.4g oriented meteorite. It looks like a weathered OC but
on
a closer inspection the back side shows a frothy brown fusion crust
with a dark interior.Could this be normal weathering for chondrite? I
would hate to cut it and find out that it is only a OC and ruin the
oriented meteorite. On a long shot maybe a Impact Melt or CC
chondrite?
