Tracy, I am always on the lookout for odd or unusual meteorites in piles of
unclassified. Out of nearly 1000 Kg I have found two stones that match this
description. I don't have any micrographs at the time but I have examined
them in high magnification and they are stone meteorites.

Keep that one, I think that a very different process was at work.

Tracy, I have seen this before in extremely old weathered pieces, especially
in iron meteorite shale, the layering is normal.
