No response to magnet, pretty heavy and brown streak at that dark spot. Chromite? Bad english sorry!

Found this on a beach in the North of France. Oily blue black on one side and goldy black on the other. The rock behind it was just to hold it in position.

Worthy of specimen pieces?



Gold and Copper? I can see a lot of thin gold in the pours but it also has other staining from oxidized material. I usually look for placer deposits and don't know if I should crush or sell them as specimens?

Need help with identification . Another one i found in Beaver County Utah at the old Lincoln Mine. Thank you !

Nice one! Looks like skarn with calcite or quartz (white) and garnets.

Nikki,
Pyrite possibly?

Hannah,
Where those "massive" rock? Not certain, but it reminds me of a small iron furnace.

Robert,
A hardness test would help. Will a knife scratch it? Try on the bottom or where its not to obvious.
I can't recall the names of possible candidates right now. Dusted?

Justin,
Better images, please.

Caribbean digger,
Epidote or pyroxene? It will "reflect" light if a cleavage is hit. A knife won't scratch it.

 

[Eu_citzen]

Ville,
I'd like a better image, please.

Dman,
Looks glassy to me. Do a hardness test with knife and quartz. (if you have one)

USMC,
Likely Mica it seems from the PC screen. Do the "needle test". Poke it. Gold is malleable, the other stuff is not.

What ever they are they are very different from anything I have and pretty to boot. Were I you I would find someone who can identify what they are composed of and maybe put a value on them. Once you know what they are you can probably research on line for specimen value too.

Good luck and I hope they are specimens of good value!

PS: Have you thought to check them with a metal detector?

I need help identifying this rock, when I found it I thought it was a fossil but i don't think so.
It has a ring to it like a peace of glass or hard clay when i tap it. I don't know what it is. I found this rock near Crestmore quarry in riverside ca.

 

[chriseneim]

Falcon md20 gives positive signal on these ? Do u see any signs there could be gold in them and what kind of rock or Quartz are they?

 

[memorios@msn.com]

My boy and I found this rock and we're hoping someone could identify this for us 😊

 

[USMC0331]

You're correct! It's mostly Mica. I put a torch to one of the specimens and the Mica turned black. I found some microscopic gold after hammering the test specimen but nothing significant. Thanks for the input!

This is definitely the neatest rock I've found out in the desert. I just started metal detecting and got a faint signal, "lower gold range". I sacrificed one of the specimens and noticed that most of it is flakey like Mica. I did find a small piece of gold after hammering the specimen, about the size of a pin head... LOL!. I lit it up with some Map-Gas and charred the rock as well. The Mica turned black and I found some micro spots that are probably gold.

I'll follow your advice and have one of the local rock clubs check out the rest of my specimens as well. I don't wan't to find out later that I threw away money! Thank's for your reply and advice!

If it is not some type of stone tool then it is probably a petrified bone or plant fossil. It is too uniform and smooth to be a natural stone. The top middle picture seems to show some chipping on the upper left (sort of like on an arrowhead) that may indicate that ancient humans chipped it for some reason (?)

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!

hay guys
thanx for the previous answers ,
I have new found today can we know what s the crystals in the number 1 and 2 pictures , and the 3 4 what is this rock is it tiger`s eye ?

Completely new to all this & very green, but my 5 yr old wants to start collecting rocks, so our family, being bookworms went & got two ID sources for Rock's & Minerals. We're not really out "hunting" for gold. However, but since my son wants "pretty" rocks we figured we would do this the right way. We are in the South central part of MO, but my job takes me to all parts of MO & AR. Now we just found this in a local creek bed that isn't traveled much. We ID'd this as Chert with oxidised Iron deposits and quartz crystals (?) In veins. We have a LOT of sedimentary rocks, limestone, clay & shale. Anyway, I was wanting to confirm what we found & if you see anything in it we missed, lol. Thanks from the GemHuntingFamily!

Welcome to TNet!

The picture is pretty blurry but it looks like glass slag. Glass slag is a pretty common byproduct of glass manufacturing and was often dumped near the manufacturing plant. The yellow orange component being litharge (lead oxide) a key component in many lead glass products.

Missouri has a long history (since the early 1700's) of flint glass (lead glass) and ceramic glaze production due to the extensive lead (Galena), barite and limestone deposits found there. Lead (flint and lead glass), barite (ceramic glazes and glass) and limestone (the common soda lime "green" plate glass) are all important ingredients in making glass.

There were a lot of glassmakers in Missouri in the last 300 years. It might be an interesting project to find out which glass maker is responsible for your found slag. Follow up from there to the source of the raw materials and you could find some nice Galena or Barite crystals for your mineral collection.

Good Luck!

 

[shaman15771]

anything in these?

 

[Ragnor]

I got one for yah, good luck

Found this today while metal detecting it was welded to the bedrock in an area recently exposed by a landslide. Specific gravity test gives 6.205, mass is 21.1 grams. Streak is black to dark grey. Texture is waxy. Can be scratched with a knife blade. Here is the kicker, a magnet sticks right to it. When polished by rubbing it on my pants for a while it exposes a bright silver/white metalic luster under the black to dark grey oxide coating.

Myself and webmineral are stumped

Here it is before cleaning


and after

Without a doubt Magnetite.

Very common stuff down here in the desert gold fields.

Hi everyone
First off, what an amazing post!, i wish everyone was so helpfull.
I have a large rock that i would like to identify, thanks !!!

I aquired it last summer, on prince edward island
On the north shore, at darnley point.
It was on the beach , in the middle of the sand,
All i saw was a peice of the rock sticking out.
Mostly you only see red rocks on pei,
I saw the green marble color and decided it was unique,
I dug it out of the sand, no similar rock nearby.
I spent like 2 hours ,rolling it and carrying it a few feet at a time, i even dented my car getting it into the back.
It must weigh over 50 pounds.
It was alot more polished, but i took a garden house to it, to clean it and alot of the surface flaked off
I can break peices off still with my hand in some spots,
I checked with a rare earth magnet for fun, its not magnetic, i see some white and pink crystals in it, very small.

So what is it? Should i smash it open, and should i look for more?

Thankyou!!

Also,does anyone know about valuable rocks on pei?
I enjoy all treasure hunting, but there aint much to metal detect in pei, lots of garbadge, and i think the soil is lowsy on pei for detecting,
Ive started reasearching rocks and fossils, i beleive i have a good location for fossils, so i may have some more rocks to post soon, anyone with tips or advice for Prince Edward Island
Such as fossil trees in red stone, i have found one just today without even looking that hard, are the fossil trees in red stone common, are they worth collecting?
