Maybe turquoise? Anyone?

Not turquoise for sure. There is some iron staining going on and my gut is that is chert or grey quartz. I would recommend getting a rock hammer or sledge and breaking it apart to get a look at a non weathered side.

Found this in Wayne County utah can anyone figure out what it is?!

Lichens and mold on some sort of solid matter. I am not even sure that is a rock underneath all that. I would clean all that junk off and then break it open to see what structure of rock you have. I cant tell if the structures in the picture are mold or rock.

looks kinda like a fossil rock but I am not sure

Hello, what is your opinion on this stone? I can see copper anything else?View attachment 1107840

It could also be a nickel based oxide and not copper. Green usually means copper or nickel oxides of some sort. Try a streak test on that green portion. If it shows light green it is copper based malachite. If it shows brownish black, it is nickel oxide or Bunsenite. I am not sure what the lower portion of the rock is. Can you see if it is magnetic and/or what it streaks as also. I am thinking it is a nickel based mineral rather than copper. I am also seeing what looks like olivine small inclusions in it. Do you have a higher res picture of it?

How about this one. Found it on my farm in Ga.View attachment 1110140View attachment 1110141

I agree. Possibly Biotite or Magnetite. Could even be weathered Schorl Tourmaline. A little hard to distinguish from the photos.

I would try cleaning up this specimen with Iron Out; remove the iron oxides from the surface.

 

[lisfisher]

Iron oxides?

 

[Tree!]

I believe these are Jasper and Chalcedony, can anyone confirm these? Or possibly a variety of Jade

 

[l337scum]

Iron oxides?

I think he means the black staining on this rock. Try scrubbing it with a brush in water first to see if any of that comes off. If it doesn't you can try some Iron Out or something like that to remove iron staining.

These rocks all look like chert to me which includes chalcendony as a specific type of chert. The conchoidal uneven fractures give it away. Jade(Nephrite or Jadite) does not fracture this way. It will fracture in splinters or granularity. I am going with Chalcedony.

Found a quartz outcropping in a couple places on a seasonal brook bank. It's super crumbly and fractured. I know it's quartz, but I'd like more info the other minerals in it, particularly the green one. There is a TON of what I believe to be mica in it, it makes the little brook sparkle and now I know where it's coming from. Is this leave-erite quartz or does it have gold potential?

This is all from the same spot. The first four pics are the same rock:

It's heavy and sticks to a magnet. I've got several of these some without quartz. I'm thinking magnetite. Should I crush and pan them? P.S. Thanks for the replies and I apologize for the blurry pics.

Hmm, I know there is gold in Ga but I do not think it will be in that type of rock. From what I can tell it seems like you would want to look for quartz veins in granite or diorite for a good chance at gold in Ga. If you live in the counties mentioned in that article, it may be worth looking for those types of formation with mica schist at the contact points between the granite and diorite.

The last picture contains Biotite in the darker portions and this is likely the source of the sparkles in the riverbed as it is black mica. The green is likely due to this being a chlorite schist and or serpentine that is hosting this vein of quartz with biotite crystals.

The picture View attachment 1111198 has some very interesting features. Particularly the far right side of the picture where there appears to be a bleb of actual gold and some other sulfides below and slightly to the left. I cant tell for sure but zooming into the picture it seems like there is chalcopyrite, pyrite and maybe arsenopyrite in that inner sparkle there. The outer one I would looks really promising but it could be the lighting of that picture. I also like the iron oxide staining all over this rock in the cracks and microfractures. I would say this one is very interesting and I recommend you assay it. Especially if that outer portion does not shatter when you poke it or fall apart. If you can scratch it and it bends, this is a very good sign.

Good luck and I hope this is a runner!

The green is likely Epidote. Chlorite and Actinolite are other possibilities. Looks like you could potentially be close to some pegmatite zones.

From the picture it really looks like pegmatite (quartz, feldspar, biotite with schrol which is black tourmaline) however since you say the black is magnetic the black portion must be magnetite.

Hi, I found these rocks around Tonopah, Az. I'm sure they are a type of chalcedony? There are a few that are fairly clear and pink. Any info on these would be great. Thank you!!

I just posted picts of a couple rocks from my claim in another section Can I move them here for you to ID?

Thank you guys! I took a finishing nail to the golden sections.... and it's not gold. It all flakes off like mica. Bummer! I'm going to take a photo of the deposit it came from. Is it so crumbly because it's decomposing? Should I break this rock up into smaller pieces and take a peeksy at it the inside?
