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. |
