[meteorite-list] E-chondrites

[starsandscopes at aol.com]

I noticed that with the heavily weathered  examples they develop a yellow 
sulfur looking powder in spots.  The OC's  tend to have a little more orange 
"rust" color.

I'm not saying this is an  accurate indicator but rather, I am wondering if 
others have noticed this as  well.

Ayeee  good question.
Im alvays a little surprized how Moroccans can recognize that  chondrite is 
E-type. From my 12 years collecting/dealing practice, I can  recognize most 
of types by eye (so Moroccans also can do this ofcourse),  except 
E-chondrites. For me they are typical OC impossible to recognize  without 
lab 
tests, especially when specimen is complete. Thats why I never  bought 
possible e-type chondrite from Morocco.

Anyone have any hints  for us ? :D
