[meteorite-list] Chelyabinsk meteorite

Sun Mar 17 09:16:01 EDT 2013

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 :)

>> 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?
