July 19, 2011 Magnified Beach Sand

Pico and ME · 07-19-2011, 10:54 AM

I grew up enjoying the beaches of southern Lake Michigan. Its really funny that this IOTD showed up today because I was just at the beach this Saturday watching the Gary Air Show with my Dad and I was wondering what the sand was composed of...figuring it wasn't shells and such.

So I just checked and found out that it is mostly minerals like quartz, feldspars, garnets, magnetite, and biotite. Heres a close up photo.
