it's a repeat!)

Hi List!


Can anyone tell me anything about the general composition of Sahara =
Desert sand? I have a couple vials that I've been looking at on my =
lunch break. Just out of curiosity, I held a Nd magnet against the =
glass of the vial and several little black specks jumped up on to the =
magnet. I looked at them under a binocular microscope. I couldn't rule =
them in or out as little micrometeorites.

The orange color of the sand leads me to believe that iron may be a =
factor in the sand's coloration and composition, and that these specks =
may just be ferrous minerals and nothing to get too excited about.

Has anyone come across this? Does anyone have any =
information/thoughts/comments?
