I was doing some metal detecting along the shores of Lake Ontario when I was on vacation. The mental detector went crazy beeping on this rock. I have searched several sources and even asked the guy at the metal detector store. Does anyone know what this rock might be?

It is solid, dull black and you can see many flecks of black crystal like bits in it. I unfortuntely can't get a good picture of it?

A picture of it might help a bit.

You didn't give much info on how large it is, hardness scale, streak or magnetic property. Making a guess I think you have a chunk of glassy dacite that is devitrifying. This is like snow flake obsidian. You could take it to a geology department at any local college or university and they might be able to tell you more about it. It is also might be a meteorite, but doesn't sound like any I have seen. More like a volcanic rock fragement.

I don't think metal detectors usually pick up rocks unless there is metal in it. Meteorites can be picked up with a metal detector it might be worth looking online if that is the rock you found.

If it was on the lakes it is definitely an iron rock of some sort

If it is smooth and definitely a "rock" it probably just has a high iron content.

Sounds like magnetite, or possibly a nickel ore.
