Thanks for that link Martin. I haven't seen that article for a while but
it's always an interesting read. I have a few unusual Taza pieces but the
one that really blew me away with it's "dual orientation" was this little
gem:
http://www.meteorites.com.au/features/taza2.html
I think it shows quite a few similarities with some of the pieces you have
highlighted. I've always found this particular feature really interesting in
meteorites.
Cheers,
Jeff

TAKE2
Hi MT,
Back in July of 2003, I posted a collection of pics of oriented irons
known then as Taza in my Accretion Desk article:
http://www.meteorite-times.com/Back_Links/2003/July/Accretion_Desk.htm
I highlighted a couple of fully lipped individuals also wondering how
such a feature could form. I believe it was Jim Tobin who suggested
that the iron was spinning like a wheel parallel to the direction of
travel and the lipping produced a "tire effect" around the surface
interior which, as is especially viewable in the specimen I nicknamed
"a bowl full of flowlines" seemed to have no directional orientation
in the usual way, and in fact, has much in common with the Allende pic
you posted.
Best,
Martin

This is an Allende. I'm not sure I understand the orientation signs I
see.
I see a star flow line pattern which indicates this side is windward. But
the lipping on the NW side hints the side is leeward. So I'm a bit
confused.
Any ideas on alternate interpretations?
