I Found this in a field WTF is it? Pics included.

I'd hang onto it, for sure. Just keep trying to find out what it is. Good luck. I hope you have something cool.

Slag, I have plenty of it in my yard from when my great-grandfather used coal to heat the house.

Is it magnetic? Try that, and also try to break a small piece off to see what it looks like inside. If it looks metallic then you might have some cash on your hands.

Looks like coral..maybe petrified coral when there used to be an inland sea in the U.S.

Possibly you could chisel off a small piece and have it assayed somewhere; maybe the chemistry department of a university or even send the sample to that meteorite guy.

Look in your phone book for companies that might have some sort of chemical testing department connected with their operations and call them.

I would keep the big chunk hidden away unless you want some doofus to pull a 'confiscation' routine on you.

volcanic

It's definitely lava.
Where my father used to live in Australia up in the mountains there are dead volcanos and theres heaps of these rocks, he stacked them as a wall in his garden.

I was always amused by them as a child.. little holes all over them and SUPER heavy!!, some of the edges were a bit sharp.. you could drop them and they wouldnt break.. well theyd break your toe, thats for sure!

Looks like a meteorite. But I have no idea for sure.

Maybe its a piece of mars, found this pic in another link of a mars meteorite!

Its the silicate slag from an old iron furnace

Ditto, we call them clinkers. Nothing special, just a byproduct of a coal burning furnace.

Phosphate.

When I was a kid I found what I thought was a bunch of what I thought were rocks that looked just like that. I found them sticking out of the ground. I was immediately interested because they looked like a meteorite, so my friends and I gathered them all up. Well it didn't take long before my idiot friend Tony decided to have a rock fight. He lugged one of the rocks at me and I jumped out of the way and it hit the wall behind me and it shattered. I was confused at how it was so brittle that it nearly turned to dust so I asked my dad what kind of Rock it was seeing as he used to work in mines. He told me that it wasn't a rock at all that actually it was a type of fungi that could be found in the Midwest. He said that the way to tell if it is a fungi or a rock is to do two things one being check and see if its brittle and two being smell it. Seeing as its organic material it does produce a smell and it is a strong musky smell. So get a whiff and if your nose feels like it just got punched it may be a weird mushroom.

Whatever it is, it looks cool

Slag from an iron smelting operation.

Slag from an old coal fired boiler that supplied steam to an engine on a train or tractor.

extrusive igneous rock with a vesicular texture and very low specific gravity

I live here in Hawaii and lava rock is very heavy

It's called leverite...

leave er rite where you found er

aka junk

cinder...

Slag/Cinder

They used to use it as ballast on railroad beds under the ties and rails

Yup

Definitely looks like a chunk of basalt if you said it's heavy. The pores in it mean it cooled really fast, and not at depth. So it was probably expelled from a volcano umteen million years go. Hit the surface, lost all of it's internal gasses, and cooled looking like that. Nice find. Congratulations, the darker it is the higher chance of it being mantle material. Your holding a piece of the earths core. That's what I can glean from it from the pictures. I would take it to your local university and have a geology professor have a look at it. They might be interested in it depending on how old it is.

cool, yeah its dark and heavy. Its not magnetic at all but I do find it strange where I found it like it came out of no where.

What does it taste like?

ha...



Dude! You were eating off it...

Unless you are a scientist, you will not be able to have it proved as a meteorite unless you test for density and specific gravity. Then you must have it tested for cosmic radiation.

I found a 10 lb stony meteorite a few years back and got my ass handed to me for just bring the stone in without that information.

I have since proven my rock a meteorite, but will never sell it.

What you do is up to you, but you must prove it true FIRST.

Good Luck

What concerns me after looking at the picture is that it does not seem to have any fusion crust or scratches after entering the atmosphere.

Why did I just get a mental picture of joe dirt pulling that wagon of air plane poop??? Ohhh Noo! Hehe!
Honestly looked like lava, however the weight does seems heavy.... I've held a rather large piece and it was light as air (resembles stone sponge look) I hope it's worth a ton of money! Good find :)
