(I tried to post
this yesterday, but didn't see it come up. Sorry if 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?
Regards,
Jeanne Devon
