Thanks for your comments Jeff. That makes sense as far as my understandi=
ng of metal meteorite goes. Maybe I should get the handbook of iron mete=
orites (~$1400). As I am sure you know, Kamacite and Taenite both form i=
n crystals. Plessite I would then imagine is a certain pattern of the K=
amacite and Taenite crystals. I am a stone collector myself so my ignor=
ance in iron meteorites is showing. But now, I guess I can look at my Ta=
za etched pieces, and the unusual almost star like etch it creates...like=
ly mimics this pattern to some degree(?). So then, if I took nickel out =
of my Tinnie, being it is a axatite, or I guess I should say, if it would=
 have formed at a different temperature and therefore had a different deg=
ree of nickel in it, it might create a pattern close to Taza when etched.=
 =20

While this was a private message Jeff, I think this might be of interest =
to the group and perhaps some iron expert out there can add to this, I ho=
pe you don't mind. (If anyone can reference me to a meteorite book other=
 the handbook of irons on this subject, I might own it).

G'day Mark,

The way I understand it is that Kamacite and Taenite are actually metalli=
c iron minerals. Plessite is a mixture of these two but not actually a mi=
neral in itself. Hope this helps.

Cheers,

Hello Everyone, =20

My typically long show report is finished, and should be up on my column =
at MeteoriteTimes shortly. =20

I won an item I believe at the Lang auction, if someone who has their e-m=
ail address handy could forward this e-mail to them....I would appreciate=
 it. (I think I won the Guffey).

I purchased a part slice of Tinnie (NM) in Tucson. It is a plessitic axa=
tite. I know Taza is a plessitic octahedrite....so now I wonder...what d=
oes plessitic mean? =20

I wanted to get one of Dorothy Norton's Mammoth books at the auction but =
because I was working it, didn't find the chance. Could you please e-mai=
l me Dorothy or would someone please forward this e-mail to her so that s=
he knows I am interested. (Fred Hall mentioned it was a good). =20

Ok, enough I's. =20
