[meteorite-list] old woman meteorite

[MexicoDoug at aol.com]

Adam and the anonymous  commentator:   Actually, it is a very good scientific 
question.   The person who asked was obviously thinking about sedimentary 
layers in the  mountains or their favorite geology text, or maybe the discovery  
channel.

I'd rephrase the answer to be:
Shale in geology is the  fragmentary-type sedimentary layer that splits in a 
planar manner usually has  high silicate content from the clays it formed 
originally from (with the help of  sea creatures).  Clays, very frequently absorb 
water in sheet like  macromolecules with high silicates so you can see where 
the planar shale  splitting derives from...You can have a sedimentary shale 
high in Calcium  (calcium carbonate) from skeletons and shells typically in 
ancient water sites.  Coals are also shales (remember the "strip" miners - an 
illusion to this planar  like splitting), when the same types of materials get 
carbonaceous.

In  the case of the iron meteorite, or for that matter, an old buried Colt 45 
or  horseshoe, the iron rusts in a manner that is layered, and splits off in 
a  planar manner....Voila - it can also be called shale for this planar 
splitting  characteristic.  Just like an onion rind, not to be confused with the 
onion  rind model of asteroids!

Saludos, Doug
(Hoping to bring my iron pick  to a far far away eucrite shale sometime and 
look for nice "diogenite  crystals"!)

Somebody asked the  following question off-list. I will attempt to answer it:

Question:
I  am just  wondering how a totally Iron body can be converted to shale  just
two Kilometers  from the original find.  No offense, but isn't  shale pretty
much  silicon?

Waiting to be set  straight.

Answer:
It is converted to iron shale when it becomes  weathered or terrestrialized
(oxidized). This is a well-known
occurrence  as far as iron meteorites go. Canyon Diablo can be found as both
iron shale  and in elemental iron form depending on the degree of weathering.

Kind  Regards,

Adam
