Number six looks like pyrite.

Did scratch test with pocket knife,it scratched it, but it was the dark outer shell.Im guessing that is oxidation if thats the correct terminology. I then broke offan edge with a hammer revealing the shinier metal and it did not scratch. Dont know if its useful info, but the weight is 1 lb 13 oz and the ruler reference to give you an idea. Its pretty heavy. It was found around KY/TN line, i just learned "around the railroad tracks". I seem to remember rocks like this being abundant by railroads. Family member seems to think they found something and have said so for 2 years. Just trying to get some resolution. I appreciate your time and input.

I recently found both of these in the sane pile of landscape rocks in West MI.
I asume to be lake bead clay at one time where it was a feeding ground for shell eaters.
I have seen places in lakes where the pike and other fish that crunch clam shells to eat the clam and it always seems to be in a pile.
these 2 stones are very dense and weigh more than they look
What are your thoughts?View attachment 1470252View attachment 1470253View attachment 1470254View attachment 1470257

Old sedimentary rock for sure. The last pic has me thinking conglomerate.

Thanks!

#1-2: Quartz or chalcedony
#3 Quartz with Limonite and sulphides. Interesting for a prospector.
#4 Diabase with quartz-veins. Can be interesting, further research is required.
#5 Chalcedony
#6 Blue quartz with sulphides. Interesting.

Help please

I was told this came from Arkansas. That it was " river rock" . It's extremely hard about 41/2 ft high maybe 2 ft. Wide ( or close). It has a black "top" and light colored innards. One side has this " brown, burnt orange , yellow color " it's made up of a whole bunch of tiny crystals it's of course as heavy as you'd think but I can lift it.

Hi! Im new here. Im from central Florida. I just got my first metal detector and found this. I have no clue what it is. Maybe someone here could help me out. This area I live in was an orange grove before a subdivision. The land around us is all phosphate mine.

This was a rock my grandmother had in her garden. I think she told me it came from Arizona, but not sure. She had the end cut off to try to identify it, but we never got a good answer by the local guy as what it was. The end picture shows the cut part wet with water to show more detail. Do you know what it might be?
Thanks!

Some kinda sedimentary rock. sandstone or more likely siltstone. The black is a coating from the river.

To blurry to tell. Do a streak test and see if a knife can scratch it.

Diabase/basalt or something similar.

Hello everyone! Just stumbled upon this site and figured it might be a good opportunity to have some experts look at this rock or mudcake or space turd (like in the movie Joe Dirt, although there do not appear to be any peanuts or corn kernels in our rock). It was found in south central Pennsylvania, United States, and looked unnatural as it was sitting on top of a dead tree trunk. Could this be some kind of tree sap formation? Anyways, it weighs 6lbs 10 oz which I guess is appropriate for its size. It is NOT magnetic. It looks kind of wet in some of the pictures but it is dry.






Thanks in advance for any feedback!

Hi, I'm new. Is this gold ore?

Hi I'm Matt and I'm ten years old, I'm wondering if you can tell me if this is gold ore? We found it at our pond, we live by Coloma California. It was one piece and I broke it up.

We think we might have a quarts vane, but we are not sure.

Back in the 90s, I found a weird green rock on the beach in South Korea. Originally I thought it was jade, but upon closer inspection, I realized it was not. The green parts are smooth and cool to the touch. It feels slippery. It's heavy for it's size, but doesn't appear to have iron in it. It doesn't scratch with a fingernail, screw driver, knife or scissors. I took a hammer to it and after several heavy blows, a small fragment broke off. It sparked when hit with the hammer. It's not opaque and light does not pass through it. Please feel free to ask any questions if you need to identify the rock.

No expert here but I guess that it is flint or chert. The sparking you noted kind of indicates that along with the smooth fractures.

 

[Goldspeed]

Here's a few that I'm wondering what may be.

The sparks only happened a couple of times and I had to hit it repeatedly for several seconds. Chert is a good answer though. I'm going to research it some more. Thanks!!
