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
