It is not a meterorite for as much as everyone is led to believe, very very few meterorites are metallic on the inside and the texture on the outside is wrong.
That is absolutely not true, it is the other way around. Most meteorites ARE magnetic, and only the rarest do not stick to a magnet. I am an avid collector and have hundreds of them, I ought to know.
While this is probably not a meteorite, and he claims to have sent it to Steve Arnold (still not convinced, since even Steve would never just say it wasn't because it was non-magnetic.) it's characteristics, especially on the outside are as close as you get.edit on 7-12-2011 by charlyv because: (no reason given)
Maybe you're right, meterorites are definitely not my areas of expertise, and they obviously are yours. The few I have which seem to be common where I've collected them (Australia) do not have a noticeable magnetic component but I have not tested them precision intruments. But the ones I have seen (and acquired) have a far more 'bubbley' texture similar to basalt, and the pictures copperhead posted do not seem to have this. I've just done a little research now and found those that are magnetic have an iron-nickel component to them. I guess mine lack that. Mine all look like bubbley little dog turds. I completely stand corrected and thank you for teaching a little more Hematite and iron ores are my only area of expertise these days which is why I'm postive it is not hematite.
This being said internet rock 'diagnosis' are always kinda tricky, and I would trust the dept. of mines assessment more than anything else as they're the only ones who have seen it in person. This and the area she found it in make this relatively straightforward.
I will also say however that the granular texture shown on the metallic core is definitely not something I'd expect to see in a meteorite, and it on that picture alone i would discount the meteor theory. For meteorites should either have a crystalline structure or if you are lucky enough to find one with a metallic core then these grains should have fused together into one homogenous lump due to heat on entry into the atmosphere.
Also having 2 tons worth of meteorite would indeed be a lucky find.
