Pretty metalic rock. ANYONE?

My first guess was Zinc but I don't know.

galena is my best guess, but its usually cubic

 

[High Plains Digger]

I agree with devildog about galena usually having some cubic areas somewhere, but this rock doesn't. Well, not much anyway. Also, this seems a little too "white" silvery, where galena is grey silvery. But on the lower left corner, is that a bit of pyrite sticking out? Are there other veins or whatever of pyrite? And where did your rock come from? Interesting. Show us the back.
I don't know what the streak test is for zinc, but if that is galena, it will leave a wonderful streak.

Interesting ,did you find that on your manhood camping trip ?

 

[DJKelly]

Here's the other side. I'm using a scanner so there is actually a couple angle not represented I'm sure but this is most of it.

 

[High Plains Digger]

Still interesting. Is all that brassy yellow stuff pyrite? Go back and answer a couple of the questions. Locale means a lot, unless it came from a garage sale or something.

My back yard at the base of a hill in Cumming GA. It was about 2-3 inches down.

does it flake easily, like with your fingernail?

pretty cool rock. you might want to try posting it in the Rocks/Gems forum too

Spectacular rock. I hope half of it is gold and the other half is silver. But in the mean time:

Do a scratch plate test on the different "colors".

Chip off a piece of the brassy gold stuff with a small chisel and then gently smash it. If it is very brittle we will know what that part is. I don't think loosing a tiny bit of the rock will hurt it at all.

Can I come rock hunting with ya'll next time I come to Georgia? Have you ever gone to the amethyst mine?

Let's figure out what this is.

Best idea: go find two other small pieces and send one to devildog and one to me. I have no idea what zinc looks like, but what about nickel? I don't know if that is found in Ga or not. Devildog

Hello from Cornelia. Since this rock was found in Cumming, it may have historical significance. It could have been thrown at Hosea Williams.

 

[DevilDog812]

well, im no geologist, but feel free to send me a piece

try sticking a piece of metal to it and try sticking a magnet to it, that might answer some questions

Great rock!
Could it be Chalcopyrite? Is it all gold & silver colored, and is the blue color a reflection of the scanner? Check out these websites:

None of my chalcopyrite has "silvery" white in it, just white veins of possible calcite. And an interesting guess from a person that knows everything about antiques that is worth knowing. But the chalcopyrite you reference is from the OTHER Georiga. It took me too long to figure out that the place names were too weird. Sorry, ya'll, but there is another place, maybe not so cool, but it also is full of Georgians.

Hey HighP, Thank you for the kudos on the antie-q's. So we have no chalcopyrite here in the good ole USA? Dang, must be a visitor from the OTHER Georgia hiding chalcopyrite in Kelly's yard! LOL Breezie

 

[High Plains Digger]

We have lots of chacopyrite in Ariz, probably UT, and I am sure some in Colorado. I just don't know about our Gerogia, yet. And probably lots of places I don't know about with heavy mineralization. I doubt it is rare, by any means. In fact, I believe the the small bits of "pyrite" I dig out of the limestone are either marcasite or chalcopyrite.

Perhaps Mr. East Georgian will bring me some of the cool Kelly rock. Any one been in your neighborhood with a really strange accent? Big fur hat with a red star on it? Oh, I know, not so hot on the red star anymore.

I'd second chalcopyrite, with some sphalerite (peacock ore) as well.

May not be well-known in GA, but you found it there, didn't you?

Easy way to test whether it is one of the pyrites or not. But it near a blowtorch for a short time. Smell the rock. If it smells like sulphur, it's some kind of pyrite.

Sphalterite in my experience can have more of a purplish-hue, but still within the range of reality. In GA, could have been something traded/cached by the Indians as well.

 

[High Plains Digger]

Ok, I just read that chalcopyrite is maleable while pyrite is not (it will break into a million small pieces when smashed). So, if you can, from an unobrusive part of the rock, see if you can pry or cut off some of the brassy yellow part. Then put it on a piece of iron or something hard and hit it with a hammer. If it flattens, then we know. See if you can get any of the white part off also, and let's see what that does.

LOL, I remember that!
