Greetings,
The Iron Handbooks by Buchwald would be the best source for trying to do
this but one would have to consider irons that may have been found or fell
after his putting the books together.
I'll take a look at these later and venture a guess.

Hi Martin,
In a way that's what I was saying.....many etched iron slices have
very characteristic patterns with regularly occurring inclusions etc
which show up differently on the cut angle....so as a project it would
be very complex and would need to show how those things differ (or are
similar) in each meteorite for different angles....but it could be a
wonderful resource if someone had the time and expertise to compile an
illustrated book.. I would certainly buy it.
Cheers,
Graham

I don't know Graham, whether that would work,
Because the same iron can look very different, just depending on the angle
of the cut plane through the crystals. Same applies especially to the
Neumann lines.
Laurence, any hints, how long those pieces are already in the collection?
Best!
Martin

Looking at your slices and their widmanstatten patterns it strikes me
there is scope here for a book about identifying widmanstatten
patterns and their subtle characteristics for individual
finds/falls....or is their already one I'm not aware of...now there's
a project for someone!
Sorry can't help with identification, I'd just be guessing....although
pretty sure non of them is Taza.

I found four unlabeled iron meteorite slices in the collection at Arizona

If anyone recognizes any of the slices then please let me know at
