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. =20 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. =20 Has anyone come across this? Does anyone have any = information/thoughts/comments? =20 Regards, Jeanne Devon IMCA #9236 www.thenaturesource.com The Museum Store/The Nature Source =20 ------=_NextPart_000_00B3_01C2394E.28753F00 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD W3 HTML//EN"> <HTML> <HEAD> <META content=3Dtext/html;charset=3Diso-8859-1 = http-equiv=3DContent-Type><!DOCTYPE HTML PUBLIC "-//W3C//DTD W3 = HTML//EN"> <META content=3D'"MSHTML 4.72.3110.7"' name=3DGENERATOR> </HEAD> <BODY bgColor=3D#ffffff> <DIV><FONT face=3DArial size=3D2></FONT><FONT color=3D#000000 = size=3D2>(I tried to post=20 this yesterday, but didn't see it come up.
