Hello Ritva_1950
I know absolutely nothing about Geology, but I have learned enough to get brave and take a guess. You can let us know when you find the real answers, how close I came.
None of your rocks are smooth, like they were worn down by a river or creek, so I don't think you found them there.
If you did, then the source is very, very, close. They haven't had time to travel yet.
For the 2 on the top row (left), I would search "transparent or colorless minerals" on the internet, they have a mineral class all of their own!
The top row 2 on the right just looks like rocks to me, although the I find the flat one curious, it's like it came from a different area then the rest (to small to tell).
The one that is middle row (left), and bottom row (right) look like brothers to me. Have you tried a magnet on any of them (rare earth is best)? I'm guessing that the 3 blackest rocks might be magnetite. With lots of iron in them they should be heavier then the other rocks, and attract to a magnet.
Out of the last 3, in the middle row, I'll venture to say, the reddish one in the middle could be hematite....and I'll go with Granite for the 2 white ones.
Can you or the other members let me know if I was even close?
Best of luck!
