Found in the area of a kimberlite pipe.

Initial reaction: Limestone. Test with vinegar. Bubble and fizzle = limestone.

Break of a section, so we can see a fresh surface.

My granddaughter found this in the creek. It has the texture and look of a landscape pebble. But what's up with this shape? And the different colors? I'm sorry but this is so strange.

Like a cookie crumbles into different shapes and sizes, so do rocks under the natural geologic forces they've been subject to overtime. Not all that sure what it is, but there are many odd shaped rocks that will be found all over world and will standout amongst all the others around it. Sounds like your granddaughter is on the right track of spotting things that are unique and unusual to everything else around it. She'll probably be good at finding Indian artifacts also.?

Bought a few barrels of rocks..trying to figure out what they all are.

Recently I bought 3 1/2 50gallon barrels from a guy who 25 years ago had gotten someone's old rock collection..no idea what some of them are? He said they were collected from all over. I'd love to find out what they all are..some I've cut so you can see them better. these are just a random few I selected.

To lazy to name all those. Research the Chalcedony-group of minerals. That should ID most of them.

Found this about 6” deep. Each round metal piece individually beeps when testing ohms on my voltmeter, none of them are connected either...I checked each one. My neodymium magnet sticks very well to it...it’s def not hematite or magnetite and not slag....please help me figure this one out!!!

This is the surface

Found with my equinox 600

Found this in my front flower bed buried in about 2 feet of hard MD clay. I find LOTS of rocks/minerals, but this one looked different from the rest.

Yep, she is the one that finds the best rocks. Her twin sister is good with the metal detector.

How do you know it's not magnetite, hematite or slag? Streak test? Will a knife scratch it? Need better pictures.
Also, chip a piece and show the fresh surface.

Quartz.

Hematite magnatite has metal spheres in it? No air pockets. No I needed to cut with my tile/wet saw it’s very hard and the color of dust is light gray

 

[GraceK1021]

not sure if I'm doing this right... First timer so bear with me haha!
Please help me identify the following.... Found.in the mountains in Oregon. Let me know if you need any additional photos info or whatever!

Maybe a meteorite?? Take a look at these links and google search stony iron meteorites. https://nau.edu/cefns/labs/meteorite/classification/mesosiderites/

@StreamlineGold Thanks for the feedback man! thought I'd share some more pictures of the area. Would this kind of formation be associated with the presence of gold?

Hard to say. Lots of metamorphic and what appears to be extrusive volcanics there. Its the right conditions..might be a feeder dike nearby.

Ignore that and look at the big picture. We ruled out slag and hematite. So we must still rule out magnetite, perhaps even arsenopyrite.
Will a knife scratch it?

I found this and a few more in my yard I live in a valley I have trued biting with a torch a small piece and it gets soft but will not melt any ideas I can’t see it being anything worth while but u never know it will scratch has some weight to it very shiny chrome like when cut but can’t break heated up a peice the result was interesting the pic in the white pal was the after effect of heat can shape when its heated that s about it

Some melted metal. Not a rock.

Purple hard rock?

Not sure what this rock is. Seems to be mostly manganese ...well, at least its purple when crushed to powder. Really hard to break even after roasting. Has some iron oxides. Had some pyrite before roasting.
