Thank you Richard. Yes, because all the fragments were found within a small area and all showed the same lack of weathering, they were thought to be part of the same meteorite, and the isotopes immediately verified that. And yes, because this meteorite is basically, as Ted Bunch called it, a "rubble pile" each fragment is being analyzed and classified independently. I do have more complete and detailed lists if you are interested, but first take a look at the list on my website (www.impactika.com/asitta.doc) you will see what I mean, I am very careful to keep each fragment listed with its proper classification.
Yes, Richard, you found a very interesting meteorite, from the moment of discovery, to its classification. Anne M. Black http://www.impactika.com/ [email protected] Vice-President, I.M.C.A.

If you buy from her you will know exactly what you are getting, ureilite, enstatite, H5, etc. because each and every fragment of TC3 she sells is being classified. ______________________________________________ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
