    pink sand beach with evergreen trees

    Would the pink sand from eroding Canadian Shield type rocks be worth looking at? I think there are garnet and quartz around

      I always think sand is worth looking at at least once, lol. Get a hand lens (like $10?) and check it out!

      Also it’s probably pink not because of garnet but because of the oxidized bedrock. I’ve seen a ton of stuff that looked like that on the shores around the Lake Superior and it was usually some form of basalt, rhyolite, or rare sedimentary interbed. You’d probably see a bunch of smaller reddish pinkish sand grains along with darker gray ones and maybe some milky quartz. But IIRC Canadian Shield stuff is pretty diverse and I recall there being some gnarly meta stuff out there so you might find some glittery mica and garnets.

        Do you know what the sand from elafonissi beach (Crete) looks like under a microscope? It really does look pinky when you’re there, and I was told it was because of a certain type of seashell that made up the majority of the top sand. I was a kid though, definitely could have been lies.

        Ok I took some mediocre photos of the sand with this cheap digital microscope, it looks very nice. Can you tell anything about it?
