[meteorite-list] Santa Fé

[Impactika at aol.com]

Thank you Bernd, Martin, Morko, and all,
 
Yes, Santa Fe is a "bitch to cut". Achim did the cutting, and it took 10  
hours per slice with his wire saw. And they are not all that big!
As for the tendency to rust, Andi Gren is going to do the etching and  
stabilizing, that means that the slices will have to soak for a long time in his  
"magic, secret potion".  
All that might explain why I won't have the Santa Fe much before the Denver  
Show.
 
As for the classification, I am going to the meeting of the Met. Society in  
Tucson in August, and I am planning on having a chat with the nice people down 
 there. And of course I will let you know what I learn from them.

"wasn't there a type-guessing contest for Santa Fe in April on  the list?"

Yes, there was and one of the most sophisticated answers came  from Rob
Matson! Anne had forwarded Robert's mail on Tuesday, April 05,  2007.

My 4.8 grams of Santa Fé arrived today. Thanks a lot, Mirko! Among  numerous 
other
interesting details, Rob wrote this: "IIIE's are abundant in  carbide, which 
makes
them a bitch to cut ... Since no mention was made of  cutting difficulty, it 
probably
makes sense to exclude IIIE."

"a bitch  to cut" is a key-word for some of Mirko's remarks in the mail he 
sent  me:

"it's very problematic to cut and polish this material because there  is an 
abnormally
high cutting loss. Some areas are so hard to cut and  metallic grains so 
minute that
there's always a high risk of a metal  inclusion breaking away.

Marcin wrote in a personal mail that Santa Fé  might be a ruster and he may 
be right because
one look at my piece under the  microscope does show it is prone to rust. As 
a precaution,
Mirko sent my  sample in a padded plastic box together with some silica gel.

Thanks  again, Mirko, and I think everybody is anxious to learn about its  
classification,
which is still pending.

Best  regards,

Bernd
