# is this a real meteorite? Answered

I found this out in the desert on one of my visits to arizona from vegas. I found this rock during thanksgiving weekend where my dad and I park at his little ranch which is very clean, no rocks at all. we spent the night at kingman for thanksgiving and on our way back to vegas we stop at our little ranch to drop some stuff off when we park I got out and found this rock in a small crater in the dirt. obviously to my surprise I think its a space rock. its heavy for its size and a little larger than a golf ball you'll see the picture.
so yeah theres my back ground story of it so let me know what it is.
thanks!

what you have is called night rose granite, google it.

It certainly could be, but it also could not (yeah, I know that's really helpful).  One thing you can test yourself is the density.  Iron meteorites have a density of about 8 g/cm3 (that is, about 8 times water).  Stony meteories have a density closer to 5 g/cm3.  Iron meteorites are more likely to survive passage through the atmosphere, and are more distinctive against local stones.

Weigh the rock, then put it into a large (quart-size) measuring cup of water.  Look at the water level before you put the rock in and after; the difference is the volume of the rock.  Density is just mass divided by volume (and you can look up the metric conversion factors if you need them).

If your rock is close to the density of nickel-iron alloy, then you probably have a meteorite.

Would I be right in assuming that iron meteorites behave like iron towards magnets?

Does that mean it will rust when it is dropped in a cup of water and left for a few days?

I would have thought "iron - magnet" before "iron - density measurement" - am I lost on this one?

i agree, it does look like granite

looks like granite

From here it has a crystalline look like granite - are those multi-coulured crystals?
If so, I'd say not.

Yeh, looking closely, it doesn't look meteoric.  The colours seem to be on the surface, though.

The open texture makes me think "volcanic bomb", but I'm not a geologist, so check further.

Do you have a Natural History museum, or university geological department you could consult?

Here is a guide that will help you identify whether it is a meteorite or not::
