Found these on the Riverbank..any ideas?

They shined 'purty' so I took em home....as polluted as the river here is it would be no surprise if you told me this was a "Toxic Toilet Rock"
..and that I am now 'exposed'

I am thinking Quartzite,or Calcite......Very nice ......I sure would have taken it home.Looks like the creek tumbled it roundish...

 

[CheathamHill]

There's tons of it..just not as 'shapely' as this one

I am thinking quartz with Muscovite, possibly pyrite to.
Try taking a pic without the lightning in sun light. It helps to minimize the reflections.

looks like it has a lot of mica pieces in it.

I agree with marine dad.....it looks like DG (decomposing granite) with mica.......
