Grandfather gave me this rock, he got it from Mexico in a mountain road they were constructing

Hello again, thank you for previous help I busted up previous rocks and got tiny amount of gold in the pan. Thanks again.

Here's one, metamorphic seems to be moved at sometime through some glacial action as it's quite smooth and flat. Has silvery flake like material, white mica? And crystal mineralization throughout the middle like a little sandwich! Interesting formation in the crystal like a winding staircase.

Love rocks thanks again, Found this close to Canadian manitoba Canada border.

I'm having a bad night but this rock is magnetic. I found it among gravels and washed stones. I thought it to be magnetite. There is a flaw on one side so inside is coarse I need to take better photos.

New to the forum. Just curious about a rock I found in Missouri by a creek. The rock isn’t that unusual but there is a spot in the center I am very puzzled by.

Does anyone have an idea what kind of rock this is. It may be a petroglyph as well. I believe I can make out some markings. It’s about the size of a “forty”.

New to the forum and fairly new to prospecting in general. Here is a picture of a sample I broke in half, one picture is with a flash and one without a flash. I pulled it out of an old mine I found in the western Uinta Mountains. I've searched every resource I can think of and can't find any information on the mine, so I'm unsure of what was being mined. The USGS reports only mention phosphate deposits in the general area. The mine isn't very big, the tunnel is only 40' - 50' long. Mostly I'm just trying to get up to speed on identifying rocks and minerals in the field and was wondering what some more experienced people thought of the sample.
Thanks!

Edit;
Going to take a guess based off the research I've done, please correct me if I'm wrong. I think the host rock is possibly a combination of chert and dolostone/dolomite rock. White calcite vein, the red is possibly iron rich chert/jasper?
I've also added two pictures of the roof/top of the mine, (at the back of the mine), is this layered calcite and hematite?
The sample was taken just below the 'roof' pictures, this part of the mine is very red, it actually stains my hands for a couple days after handling it. The sample itself felt much heavier than other rocks of the same size in the mine, mostly the reason I brought it back with me. Wasn't magnetic enough for a magnet to stick to it, metal detector didn't pick anything up in it (older White's MXT) I have attempted to crush and pan about half of the sample, don't have a rock crusher so was just trying to smash it up with a hammer, was actually pretty hard and more difficult to break up than I thought it would be. Some of the heavies are magnetic, most that are not magnetic have a dull silver metallic/glossy (not shiny) look to them.
USGS geological report says the area is mostly classic sedimentary and carbonate sedimentary.
Any input/thoughts would be greatly appreciated, I've certainly exhausted my knowledge and then some haha.

Hello,
take the below with a grain of salt. My sedimentary rock skills aren't quite as sharp as they used to be.

I'd take anything "waxy" in luster and attempt to scratch it with knife. Scratch probably = Carbonate.
No scratch = Chert.

Because my knowledge on sedimentary rocks is so rusty, I'll just mention there's some nice faulting going on in that pic.
Which may warrant a keen, curios eye. However, I'd not expect as much gold as I'd expect base-metals.

Does anyone know what this rock is found it in a field while cycling also I’m new to this forum. The rock is very heavy and very big no idea what kind of rock it is though appreciate any help View attachment 1617693View attachment 1617693

A nice blurryite!

Could be magnetite.

(botryoidal) hematite on host rock. (quartz?)

Bixbite with unusual surface etchings, maybe some striation. You're rich!

Check this "rock" out.

I thought it could just be a magnet that came loose off of a piece of machinery and after tumbling around a wash plant for a long time it got out. It is magnetized one side stronger than the other. I don't have a clue but does have scratchy one side but not deep.

I saw a different snake. Until I saw the snake.

What is this?

Glass-slag.

Can you tell me what this is?

We found this rock in our backyard when we uncovered and dug out a 160yr old root cellar. It fell out from behind one of the walls.

Last two pictures male me think quartz, would help maybe to tell location.
