Help ID these rock... Please.

[Stone]

I found these rocks a while back and I'm not exactly sure what they are. These are very light weight and look like they have been melted. I believe they my be some kind of lava rocks. Any ideas?

 

[Stone]

Forgot to mention, the ground where I found these is littered with them.

Anyone have any ideas as to what they are?

Lignite or turba coal.

Thanks... I was hoping they were a cool find but I guess not.

I'd like to see the other side. It doesn't ring a bell quite yet.
Can you break one open and see what it looks like inside?

 

[Stone]

They look pretty much the same on the other side but I did crack one open for you.

Look up basalt, could that fit?

Try burnning one. If it burns then Turkish Man is correct.
Basalt is a dark volcanic rock but it would normaly be described as heavy.
Rhyolite is a lite volcanic rock but it is normaly light colored.
What about these rocks makes you think volcanic?

They kind of resemble a cooled blob of magma but I have a feeling Turkish Man is right.

Where were the specimens located. State, where in the state, by a river, etc....
