I have to agree with the Count. I've seen metal content within type
specimens range wildly. Some even have metal blebs that would lead you to think
it's a stoney iron using a magnet test.

Hello Shawn.

I think you may be oversimplifying the composition of individuals and
frags of the same fall. It would be remarkable to me that each portion of a
specimen would have the same percentage of metal. I don't think whatever
process creates a meteorite involves the surety of an equal distribution of
elements throughtout by volumn.

Some areas of the meterorite is gonna have more metal and some ain't. That
would acount for a specimen having different lithographies like Almahatta
Sitta for ezample.

I'm operating on short info here, but I think ya'll get the drift. But,to
answer one of your queries, all nine of my little Pultusk looking peas of
Chebarkul had the same unscientifically measured attraction to a neo magnet.

super strong. My question is, with some of the historic meteorites I have,
can over time, the strength at which a LL or L or even a H meteorite increase
over time, due to oxidation and or rusting? Why I ask is because is
because I have two meteorite samples that fell in 1803 and both are from France,
but two different falls and are both L6. One sample is is less magnetic than
the other. The one that is stronger has about the same attraction and
pull to a H7 Forest City meteorite. All three meteorites come from top dealers
and collectors, so I know the authenticity is genuine, but it seems some
stones can have anomalys within, when tested with magnets. Has any other
listers noticed this, and if so, why would this happen? I have also heard that
some dealer has devised a full proof test to test stoney meteorites to see
if they are LL L or H or HH, or did I just make up HH :)

three different foreign sources resemble themselves. The specimens I have
look like they could have come out of that pile that Mike Farmer posted.
Mostly small individuals of less than three grams, black even fusion crust, no
other coloration, regs, no cracking except for a few fracturing in flight
with the result that the interior lithography is covered by black fusion
product. None but a few that I've seen so far show more than the smallest
impact marks and those display a typical grey chondritic, almost Portland cement
 color. Most landed on snow so have remained pristine. Heavier pieces will
be recovered when the ice and snow melt. They are strongly attracted to a
neo magnet and set off a detector easily, so I'm a little curious about the
initial classification I've heard. Is LL6 S1 W1 and named
Chebarkuhl..correct? Anyone...Ted?
