Metallic ore?

[BeerBelly]

My daughter found this rock at a park yesterday. I helped her break it open. She wanted to takeit home, so I said ok. Today, I noticed it was in the garden next to some plants that are being grown for food. I became concerned, and thought I should check it out. So, what is it? Is it safe to be around food? I've been trying to find something simialar on the internet but the only thing I found was Iron ore? One pic looked a little simialar, the other pics were far from it. Any ideas?
Thanks in advance!

It's not magnetic, the rock is very smooth and rounded on the outside, (river rock?) and it came from a city park in lost vegas, nevada.

You're safe. It looks like common granite.

The brown rock looks like quartzite. Also the shiney flakey material is probably a mica schist- A quartzite rock bedded with a mica schist on top.

Either the above or an example of a deadly radioactive rock called KILLROCK. It is so radioactive that a 30 second exposure will make your testicles turn black and fall off in about 48 hours. If they do not it is indeed an example of quartzite.

Good Luck

I know that was a joke, but you can find radioactive ores and fossils in nature, luckily Uranium in nature is weakly radioactive compared to the radioactivity found in many consumer products if your curious you can search the web....
