Any Geologists here?

If I mess with the color settings, it's green so it must be kyptonite. If I don't, it could be a constipated meat-eater's coprolite. :biggrin:
 
OK. I sent these pictures along to a geologist I know. He said he couldn't make a definite ID without holding it in his hands or busting it open.

He did not think it was a meteorite. His best guess was that it was a cobble of weathered metabasalt that came from the north via glacial and/or river transport. The pockmarks are crystals that have prefferentially weathered out.

That brings to mind two questions

1 - is metabasalt still a cool rock - how far from the north would it have traveled?

2 - is metabasalt like metadata - a basalt made of other basalts? :wink:
 
I think the only question he cares to have answered is this one:

"Is it valuable?"

I would think he should have plenty of money from his success in the commercial business..

I can't help with the rock discussion.

I can tell you that if you need a powerful magnet, tear apart an old computer hard drive (you'd be surprised how many people have them sitting around).

They have extremely powerful magnets in them.

Good advice, but come on man, let's be realistic. You and I both know that the OP's not tearing apart a computer with hands like that. He probably has enough trouble peeling a banana, let alone cracking into a computer case. If he wants a magnet, he'll have to use a crowbar and pry one off the refrigerator.
 
I opened this thread expecting it to be about Perrault pulling you into an argument about whether or not the molehill was actually a mountain, and you just wanted some back up.
 
I sent a picture to a guy who worked on the very first sample of lunar rock from apollo, he said this:

Do you have a an volt/am/ohnmeter? Does it conduct electricity? I
can't tell if it's metal of just a chunk of iron oxide:

Do a streak test:

It it were mine, I'd cut it in two to see what's inside. I can't tell
from the outside, but I can see why it caught your attention.

I am a graduate student in geology. We generally don't do meteorites here at ISU, but I do know a little about them.

I thought the vesicle theory was good, but then I would say that those probably aren't volcanic vesicles, because if that were the case the rock should be lighter than normal rock. Vesicles are usually formed as air expands within a rock when it is hardening (usually due to a change in pressure during a volcanic eruption).

Meteorites don't necessarily have to be highly magnetic, it could just be a stony meteorite with a lower nickel/iron content. It does look like other meteorites I've seen, but I'd be hesitant to declare it as real without seeing it myself. If you brought it to Science I on campus during the week we could check it out.

If it does turn out to be a real meteorite (and your hands are regular-sized:smile:) it is pretty large and could be quite valuable. But like I said, it really hard to identify rocks from pictures.

I'd listen to this guy, he's a pretty good TA.
For what it is worth, it's texture does not appear like the meteorite sample I have from Meteor Crater AZ. But if it somehow turns out to be, you're going to have a pretty valuable sample. I think I paid around $15 for a sample the size of a nickle. :yes:
 
Ok, this is random but I knew CF would already have a thread like this. My daughter had picked up some rocks along our gravel road and one looked interesting. Of course she got interested at one point about meteors and asked my wife to test it. She obliged just to teach her some steps but it became more interesting as it seems like it very well could be a meteorite. This rock is magnetic, although not homogeneous, and fairly heavy. It weighs about a pound (my more accurate kitchen scale won't turn on) and about the size of a baseball. I sanded a portion and it has a metallic like grain but I used just a wood sand paper.IMG_1560.JPG IMG_1561.JPG IMG_1565.JPG
