Looks like alot of the Petrified Coral we find here in NM, it gets bound up in sandstone, and eventually weathers out in some quite amazing shapes.

my camera doesnt capture it vary well but this rock is full of green crystaly stuff the darker areas are actualy green I found it on a hill full of Quartz and the last one I found in a mine shaftView attachment 868061View attachment 868062View attachment 868063View attachment 868064View attachment 868065View attachment 868066

the "Green" crystals are most likely Olivine in the Quartz/ Mica matrix. nice rocks.. you keep your eye open for any the size of a pancil eraser,, or bigger there about 28$ a carat, and i've seen some go way more ..

Some kind of quarts stone with goldish rivers running through it.

I still think its a sulfide.. hey have you got a Tile saw? cut one right thru the center, wax the cut part and take a pict! or send me that one right there and I'll cut it up.

Dusted,
I crushed up another small sample and got what looks like merc. It is really heavy. It does not roll like merc though. I have no clue. Can you identify? The third pic is the vein rock that I crushed. We are six to seven feet in.

most Silver is found with Galena, altho the Structure to this rock is NAICE! Ok so Galena has a Cube Structure to it Square... the Silver in its natural state looks like folded melted metal. or it turns black with exposure to oxygen (white in Clorine).. Copper is almost always found with silver, My personal feeling on this is you have a Very NAICE Chunk of Native silver,and should probably have it assayed ! Immediately..lol VERY NICE FIND!

Thanks Dustedyou for the info. This metal is really hard and I could not scratch it with my fingernail so I got my hammer and had to hit it pretty hard to put the dents in it that can be seen in the pics where I scraped some on the powder off of it to get to the shine that is a dull shine none the less. Thanks.

Thanks Dustedyou. How do I find someone to assay this piece and where do I look for a assayer? I live in southwest Va.

Hey guys if you have any rocks you want identified,, or are having a problem with the composition, Post it with questions, and a brief summary of where you got it..I'm down to help!

And I love to play Stump the Chump!

Hello Dustedyou. Found this rock in my quartz inventory. Can you tell me what it is with the green in it and it really has a lot of sparkle in it too just like little diamonds and I would like to see what's inside but I am afraid to bust it. A lot of the surface of the shiny side has a shade of green. I also turned the rock with different angles for you to see and turned it over and displayed the bottom side too. This thing is beautiful. The one pic of the little rock that is in there is by accident but it has green in it too. Could this mass also have Fe-Rich Olivine crystals in it. It has one chunk of quartz in it too. Thanks.

This rock is here in So Cal, It,s heavy mineralized but I dont know? Thanx.

Holy crap!! Did I actually get one right? Found this thread over in the metal detecting forum and sent G Freeman over here. Dusted, your a bad influence.

Hi! Fantastic thread! I'm still learning how to post pics so I might not be able to..but..I have a rusty quartz sample I found the other day that had a lot of black on it..the sample seemed unusually heavy. When I got home I started crushing it and to my surprise it broke open to expose a matalic silver material. Sparks came from the rock when I hit it with the hammer..kinda smelled like burnt gunpowder when it broke open.. I can pick up the black portions of the sample with a magnet, but the shiny portion was not magnetic. I tried scratching the shinny part with a screwbriver to no avail....I looked in a few of my rock books and everything with a silver shine should have been scratched with the screwdriver..this rock crushed hard..its not in cubic form and does not flake apart..after reading the description of arsenopyrite I heated the sample with mapp gas (outside) and low and behold it became magnetic,,and crumbled apart. When I pan the fine ground sample there is some kinda shiny stuff that is very very heavy but very very small. Does not shiny like gold but almost..hard to tell when it is ground so small..there is a small ammount of gold in the sample...any tests or suggestions would be great, thanks.

OK Dusted ive been digging under this Quartz vein were it turns that red,orange color ive been crushing it but no gold. What do you think of this orange material and should i keep digging here or maybe down left or right farther? Im a rookie I need a clue.

 

[hbprospector]

That first pic looks like feldspar and quartz. No gold there that I've found.

Thank you!

Here's a couple more. The black "rock" is attracted to a magnet. Ignore the pink paint on the smaller rock, it was found in the low tide area of a drydock and caught a little primer...

 

[timberjack]

Working on posting pics of the rock described above hope it works. Sent it off for an assay

 

[timberjack]

Hot damn, I think I have got it! Also found this-alot of this in the same area.

Another rock for your opinion

One of the rocks I found in a clay fissure in bedrock about 10 feet from the surface. Was wondering if the lattice texture of the deep brown mineral was an indication of boiling an what it could be? Appreciate you taking the time to respond to all our inquiries.

Found this quite heavy rock in a campground in Michigan City, Indiana, where it stood out from the rest of the drainage rock that appeared to be igneous (or perhaps a slag by-product?) and very porous, with a few black obsidian pieces mixed in. I was attracted by the surface on one side of this rock, which looked like woven fabric. I'd love to know what it is, though my spouse made me leave it there in case it was uranium or something similarly radioactive!

Dustedyou - are you still willing to identify rocks if I send pictures? Wish I could be enjoying a breakfast there at Weck's and watching the balloons.
