Lead and cleaned. Sorry my phone auto corrects. Just to the wrong word lol

Jonezy, more likely is that this is a quartz-related mineral. perhaps chalcedony.

I picked up this rock slab at rock and gem show.

 

[Eu_citzen]

Interesting piece Marty. I have no idea what you got there. In what area did you find it, roughly?

Fozzie, didn't you ask the seller what the slab is?

 

[mamabear]

hmm, interesting pieces. Was it the show in St. Louis this wkend? I didn't get to go.

bumping mine. I still can't figure this out. Thanks

Found these while I was digging for crystals. Any thoughts would be great. Thanks

I have been wanting to get these rocks identified for awhile now. I found these in the Lancaster, PA area. These were found at the bottom of what looked to be a run-off from a mountain. There is also a small stream running perpendicular to this run-off, which is about 50 feet away. There were plenty of these small rocks in this area. They differed in color - dark green, dark blue, and some greyish ones. Some almost looked to be glass, but not sure. Anyone have any ideas? Thanks!

Hello Cheatham, unfortunately the pictures are bit to blurry to make out details. Try taking new ones.

DavidH, Likely pyrite and another grey-ish sulphide which is difficult to make out.

Smitty, slag seems to be a possibility. Glassy things can be very difficult to make out from pictures, some historical research can help you! (i.e. smelters in the area?)

Looks like flint, or could be volcanic glass how hard is it? can it be easly chipped?

I live in east tx can't remember how I acquired this rock but it has an iridescent gleam when it hits the light a certain way

 

[Aimblv]

Here's another it might just be dirty though I odd wash them off and let them soak a bunch times and this one still had that orange color kinda mixed into it

 

[Aimblv]

This one is really neat my thumb fits perfect in two different spots and got these little crystals some are bunched together and some are spread out and flat within the rock

 

[Kev123]

Can you identify this rock please?

 

[Aimblv]

Kev is this rock similar ?

 

[Eu_citzen]

Oh my, someone's been busy!

Ok, Aim, here we go:

1. Quartz. The iridescent effect you see may be due to a thin metallic coating.
2. Concretion? Looks sedimentary in origin.
3. Could be a number of things; calcite, zeolite and quartz.

Kev, can you scratch it with a knife? Magnetic? What colour do you get if you rub it over a unglazed piece of porcelain?
