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.

Regards,

Count Deiro

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 :)

>> All nine Chelyabinsk/Chebarkul individuals that I have purchased from 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?
