This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Ok I took some mediocre photos of the sand with this cheap digital microscope, it looks very nice. Can you tell anything about it?
Awesome photos!
Whoa you were not kidding about that being pink. Holy cow. I mean..the pink grains could potentially be garnet but I'm a little doubtful and unsteady at saying that for sure. They have conchoidal fracture and a vitreous sheen which could easily be quartz, perhaps stained by something else going on in the area (Mn? > Fe).
Those blue green grains are fricken neato, I don't have a good explanation for them and can't really get a good look from the photos.
I see a couple of green grains that could be epidote or some other green mineral, and one that looks a little olivine-esque but it's hard to tell.
It's one of those things that you poke and prod and rotate and stare at for a while before giving a broad, hand wavy guess.
It would probably be helpful to look up the location and the formation to get a better sense of what to expect.
Either way, those are dope!
