Hey, I've found some rocks which look a bit molten. Location is in the mountains at an altitude of 1,400m above sea level. I'm figuring there has been a light stream passing near many years ago but now there's nothing, just a river-like pathway. These are the photos:




I hope the images are clear, any feedback is appreciated.

This is a huge rock. It must weigh over 100 pounds. I’m trying to figure out what it is. I think my father found it 70 years ago in the Napa valley river, but I’m not positive. The rock is pink and white.

Would love help identifying this rock. It was found in Michigan but in a flower bed of red rocks.

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.

Quartz.

Posted this in today's finds.. http://www.treasurenet.com/forums/today-s-finds/585810-unknown-rock-atleast-me-help-please.html Any idea what is it? Its 100% magnetic across the entire surface of the rock.

Do a streak test. Rub it on the underside of a porcelain toilet tank top. What color is the streak?

I did this. It does leave a streak behind. I did this with various positions of the rock. It leaves a black line streak and a rust color (red/brown) depending on how I position the rock. I suspect maybe this rock is composed of magnetite and hematite?

Thanks

That would be my guess and I often find both when metal detecting as they are very common in mineralized areas.

Hello,

Found this metamorphic type rock near manitoba Canada border, noticed it had silver coloured pieces of metal in it. The metal and entire rock is Non magnetic whatsoever. I checked with a large strong niobium Magnet.

I broke open the rock and panned it, I had a lot of silver coloured "heavies" and small silver coloured nuggets that I could pluck out with my fingers.

Further- There was absolutely no magnetic black type sand in the pan. The silvery material seems NOT of great density in relation to that of copper, silver, gold, platinum. It seemed even though I used some detergent I still had a silvery material that would adhere on the surface of the water.

Some of the nuggets I could powederize with pliers by squeezing, while other pieces of seemingly the same material I could not.

I hope this is of help to figuring out what this is. Again I thank the site for the help. Have a great day!

First 2 are chalcedony, last one (druzy) quartz.

Chip an edge and show the fresh surface. Looks kinda like chalcedony. But I'm not sure.

I believe the geological name is 'the people's eyebrow'.

Thanks EU Citzen! Appreciate the help and input!

Thought I would throw this up here and see if anyone had some idea's. Crushed a small amount of material from an old mine I found (1 of 3 within a couple hundred meters of each other). The material was mostly canary yellow in color and stained everything it touched, bits of brownish red mixed in. Should have taken a picture of the samples before I crushed them, looked very similar to pictures of limonite I've seen. The picture is what I found after panning down the crushed material, metallic silvery luster when wet or dry (is wet in picture), when dry it almost has a dark greenish look to it. Is not magnetic, a few of the black specs in the picture did react to a magnet. It acted very heavy when panning it, can't say how heavy compared to gold in a pan as I haven't found any yet haha. It doesn't move easily though and it was very easy to wash all of the other material off of it. I did heat it up in a skillet on my electric stove, as hot as I could, no smells that I noticed, didn't react to a magnet after being heated.
Any thoughts or input would be greatly appreciated.
Thanks!

picked this in north central WI. It is a couple of pounds in weight and very smooth, found in a glacial till hill. In the pic it looks brown but in sunlight in person has a burgandy color. Not able to scratch with a knife.. note the patch of crystallization on it
