Help me ID this rock

I'm certainly not an expert, but the green looks like serpentine, with inclusions of other rock, perhaps basalt with some quartz also showing. Somebody will know for sure.

Looks like a hunk of cooled slag to me. Where'd you find it. ?

North Central Kansas

I can't think of any natural rock formation from any region of Kansas you wound find something like this. I believe it's a piece of glassy slag most likely transported to the location as railroad ballast. Here is a link to another TN post about the same type of find. http://www.treasurenet.com/forums/n...ifacts/381371-creek-hunt-what-type-stone.html

What is slag?? Does it have to do with oil drilling??

 

[trdking]

Slag is anything scraped off the top of something melted. The unpure junk that rises to the top. In this case Glass

Depending on the weight, the center looks like petrified wood.
