meteorites?

[Kevin]

From the pictures, none of those are meteorites or tektites (ejecta). SaltwaterSlick, you are mistaken on this point. Everything I see posted are from iron ore concretions.

That's what I thought. Just can't figure out why the lines are on there in the shape of a cone...

OK, but we'll have to agree to disagree. May be iron ore, but they originated from a meteor impact somewhere.

Mac... I agree, that is interesting. Im not an expert in all things rock, but due to the extensive heat generated when a meteor enters the atmosphere, the surface of the rock just looks different. You will see flow lines and lips where the metal melted and then hardened again. In your example, if it fell from space you would see melted metal lips coming from the non-pointed side over the lip, or at least melt patterns, which arent that defined (as in your picture).

Here is a pretty good example of flow lines and rolled lips.

Lol, that rock is wearing a hairpiece. Lol

Thanks for the info

[Kevin]

Mac, how heavy are the rocks? Do they seem so heavy you think, "weird that seems like a lot of weight for a rock!"

This guy is a bit of an a-hole, but gets the point across lol

Yeah, they're all heavy. Much heavier than a rock that size should weigh.
I figured they were all iron ore.
Just the 2 that had the distinguished marks were throwing me off.


And some are magnetic and others aren't.

[Kevin]

Are they magnetic?

[Mac...]

See above post

In this particular case the rocks are iron ore nodules/concretions. I'm not sure about the other rocks shown later in the thread. I suppose those could indeed be meteoric in origin. But then, I'm no vulcanologist. Just a rock hound that looks for oil.



Geeze I sure hope I spelled that right.

100 percent Concretions, I can walk next door and pick them up all day, some big as baseballs all the way down to marble size..

Rabbit dinosaurs used to be a lot bigger than they are now days. Just sayin....
