Got A Rock you Want Identified? Post it here! gimme a good picture or 3 or 4!

Pyrite ? Arsenopyrite ? Silver ? Some kind of telluride mineral? It feels like a brick so heavy for its size and has all these little holes all over it with shiny silver and gold colored minerals all over it. They do not crush crumble they just make indents when poked with knife. I got it from taking piles in Alma Colorado at the old gold and silver magnolia mill mine. And it's not magnetic what's so ever

Hi,
I have these rock specimens. I have a post on here about is it gold or mica. But I wanted to know if you saw anything significant in this video. I am new to prospecting and got fooled by some mica. I appreciate your help.

Hello GeorgiaGold, looks like you got into the same stuff I am eat up with. Muscovite a form of Mica that is gold in color. I thought mine was gold so much I sent some to be assayed,boy was I fooled. I am no expert and by looking at your video I don't think anyone could tell you for sure as this stuff looks so much like gold. I hope yours is gold. Good luck. Just my opinon.

Couple more I could use some help with-

Meteorite fragment? You may wish to have it sectioned and acid washed...

Thanks SheldonJ. Where would one have this done and what type of acid? He was thinking of having a corner cut off so it could be mounted on a stand. At 21 pounds it is surprisingly heavy.

Does anyone have a clue what I have here, I was playing around in a pegmatite vein an this little guy popped out, its very light pink translucent it kinda has the structure of a morganite but not to sure any ideals

Heavy Hunk of Rock

A friend asked me to find out what I could about this specimen.
It weighs 21 pounds.
It displaces 6 cups of water in a bucket.
Dimensions are roughly 7" x 6' x 4 1/2".
It is magnetic but more so on the end that looks volcanic.
It came in a load of rock from the California Sierras.







Any ideas?
thanks-​

Break it open with a hammer so we can see a fresh surface. Use eye protection.
Strongly magnetic?

Okay, Mr Lee and I have discussed these two specimens. Let's see what you guys think. The first 5 pictures are crystalized quartz, mostly. What else is in there? The next 7 are of a rock found really close to the first. It wasn't pretty, the material looked comparable so I broke it up. What do you guys see? The specimens were found in Hart County, GA, on my property.

I see quartz crystals and pieces (?) of country rock.

I am going to suggest chalcopyrite, it looks like sulphides to me. Chalcopyrite can indent slightly when poked with a knife.
Do a streak test, rub against an unglazed piece or porcelain.

Your second set of pictures look like more copper-related minerals, like bornite for example. Some have a coating making it difficult to guess better then that..

Lead ore with silver in it... would be my guess... been finding alot of it my self in Cerillos nm

Ah yes, Cerillos. Last time I was there in those hills on a horse I looked down and there was a piece of turquoise the size of a quarter. Amazing place.

I can't seem to get any answers perhaps you can help me ID this

broke open the breccia rock that had the reddish cap on the top and what looked like a reddish gold vein running through it. And when to broke it in half the vein is shiny and runs through the whole inside. What do u think

Found this rock/stone (also posted in a thread on this site) in Manila Arkansas in my great-grandmothers garden many years back...

I don't know a rock from a stone but if I had to guess I'd say amethyst geode. cool piece.

I still think there are some copper minerals in there. But I could be wrong, if you want to tell gold from sulphides your better off doing that yourself.

I think your right it seems a bit faint and translucent to be gold.

I found these in a little creek in BC Canada. I am told that the rough (stained) ones are granite. With the magnifying glass, the black parts almost look like tiny crystals? There's lot's of micro sparkly's that I believe and am told is Mica, does Mica sparkle in silver? The rust is just rust I guess?
The little smooth ones have a sort of grain to them, I made them wet hoping it would be easier to see. I'm told they are Gneiss? Nothing about the grain or rings though. I think I'm going to get a claim where I found them.
I like my rocks...lol.

 

[Eu_citzen]

Chrisenim, if it is translucent, I doubt it's the copper minerals but rather the quartz you are looking at?

Wishbone,
Your first 4 pictures do resemble a granitoid. The others look like river rock, perhaps I see some quartz in there. The others I'm not sure.
