I think this theory has a potential fatal flaw if what we think we

Good afternoon everyone,
Some members have expressed yesterday their displeasure in the recent threads
about alien life and movie/TV
trivia. Well, here're your chance to discuss meteorites. Several weeks ago I
had asked about silicated Campos.
There was only one reply (Thanks again, Joe K.).
Hi Carl,
I recall you asking this question and I'd like to hear an answer also
- in fact, I think I was one of the few people who replied, although
my reply was the same as this one.
Best regards,
MikeG

Hi Carl,
I recall you
There are three principal goups of silicated iron meteorites: the IAB-IIICD,
IIE and IVA groups. Recent work seems to indicate that the IAB and IIICD
groups are related. Iron meteorites that are thought to have formed by
fractional crystallization processes have certain slopes on

OK, I think I see the subtle difference. I have had to re-read Dr. Rubin's post
several times to get the picture (Thanks to MikeG, too). Simplified, an
asteroid slams into another planetary body right to the iron core and forms
mesosiderites. That part I knew, but when smaller iron

No apology is needed, Dr. Rubin. You are crystal clear. It's just that I'm as
dumb as an ox. It takes a bit of doing on my part for all that information to
sink in. You've also explained the two inclusions in my little slice of
Muonionalusta! I had wondered about them as well.
So after the
Alan: Well done! Carl: thanks for persistently asking a simple question with
a complex answer. I've often wondered about this myself. I never
understood how some Campos (or Odessas) could be silicated and others not. I
thought it had to do with Earth impact, (duh!) Thanks for saving me

Arlene,
Someone just explained this not too long ago. If I recall: cooling is a
factor, but mainly it's the amount of nickel in the meteorite that
determines the pattern. The slower it cooled, the larger the interlaced
crystals of taenite and kamacite, both iron nickel alloys. The width of
14 matches
