Got A Rock you Want Identified? Post it here! gimme a good picture or 3 or 4!

Found in a river in the UP. When it's wet its purple/red tones really come out. This is just a photo of it dry. I've had it for a few years now, and it's definitely my favorite natural find. The other side has more circular spots which makes it look like a dragon egg. I'm curious if anyone has seen similar rocks?

Its in a rock maybe ten by five inches foot print.

 

[SISTEROFSPECK]

is this some kind of wood it is very light in weight.

 

[SISTEROFSPECK]

this is an arrow head what is it worth. it's from Indiana

 

[Fumbles]

Found this digging in my front yard in Portland Oregon. Any clue what it might be?

 

[Stephydee]

Can you please share your knowledge on what type of rock /mineral these are. They came from So. Cal Palos Verdes.
Ty in advance

Cheers for the book tip. Thanks again. As for the puff pastry one. I think it is a micaceous aggregate of hematite.Just never seen it in that form before. The streak is more rusty orange than red.But micaceous formation of hematite is the best I can come up with. As for the other bit of weirdness.Tried scratching it with a knife and it just transfers stainless steel to the white stone. Scratch test only produces a streak from the black bit which is grey.Pretty heavy and hard. Quite a hard area to work with a goldbug. Lots of rocks go off in non ferrous and slag is just everywhere.Had more luck with using eyes than a detector here.Just too much sets it off. Weird area.Pretty cool though.Peace

Rusty orange? How about limonite? I've seen it do something similar once in a while. (please note; limonite is a group name for ironhydroxide-ish minerals)
Look around, see what they've been smelting. Might be useful/interesting to know!

Possibly sandstone. An odd one for sure, but neat!
For a proper ID, for future reference, always use the hammer to chip of and edge and show me the fresh surface. It helps LOTS to see the luster of the rock.

A sedimentary rock is my thought. Can't see much to give a better ID.

View attachment 1476568 is this some kind of wood it is very light in weight.

Metamorphic rock. Banded schist perhaps?

There's an indian artifact forum for that on Treasurenet. Try it.

Most seem to be chalcedony. Last one might be micaschist or something similar.
The reddish one might be syenite or even a porphyry like rock.

Any guess?

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!

Hello, I would love to take you up on your offer.

The pictures attached are what I found at local public beach. It is:

1. Magnetic
2. porous surface
3. appears to have a crystalline interior.

Help?

Thanks

Mark

Glass?

I thought so too but wasn't sure. Thank you for confirming what I thought. It looked last me a big marble gone wrong to me but was strange to find it about a foot under my lawn digging for a fence.

Hello Eu citizen. Tried to answer this myself but drawing a blank. A silver looking nugget. Reacts strongly with peroxide and potassium hydroxide. Very strong reaction with peroxide,boiling it all away and leaving big bubbles only that show no sign of bursting. Just as strong a reaction with peroxide as silver or platinum. I did try to answer this stupid question without you.Just no luck. An add on. After the peroxide had all but gone except for huge bubbles that showed no sign of bursting,I added a bit of water and left it.On returning to it,the water is now like a gel. The photo is of a test tube with said metal held upside down.As you can see,the water shows no sign of wanting to come out but the metal still moves freely in it. Quite weird.In potassium hydroxide the precipitate just looks rust brown. The density means little as the nugget is also full of matrix.It has a pleasing ringing sound when struck with a coin.Thanks for your thoughts

This isn't so much about the rock, rather the silvery/pale silver stuff in and on it. I do not think it is mics, but I could very well be wrong. Hopefully you may be able to tell me more..Thanks in advance.

Im not sure if the pictures are showing up but they are clear and crystal like. I found them while panning in the snake river in idaho.

Do a streak test. Likely magnetite, which will produce a blackish streak.

Your failure is due to you using the wrong methods. No hydroxide is used for mineral ID work, it will at best be used to check for gold in sulphides.
Do a hardness test, streak test for starters.
