identification for this stone

Recommended Posts

The stone doesn't look like anything special, what is it that compels/interests you to find out what it is?

That being asked, more info is needed to help determine what it is.

Do a streak test and tell us what color the streak is, e.g. rub the stone on a streak plate/unglazed ceramic tile, the underside of your toilet tank lid will work great if you don't have a test plate.

It scratched up the porcelain( or water deposits on same.. )

Basalt or a Manganese nodule,

Leaning towards just basalt as the surface seems porous.

Or I suppose chert or flint. They're both quite hard, as well.

Can you hit a corner off with a hammer to see color inside and see how it fractures??

. Chert and Flint will break off like arrowhead shards.

Find a hammer, togba, and hit a corner of it to break off a chunk -see what the insides look like.

What's the local geology like- where'd'ya find it?

I'm guessing there was no color on the porcelain tank lid?

Okay, how about windowing the stone?

Hi Togba,

To "window" the stone, you don't have to have the bucks for a lapidary saw. The fastest device for putting a window

in a suspect specimen, is a low-cost sharpening stone from Home Depot, or your local hardware store. Just use the "coarse

side" on a corner of the rock. After you have made a dime-sized or larger window, flip the stone and use the fine-grit side.

When smooth, rinse the rock dust and look in the window for chondrules, or metal blebs that will have the color of fresh-cut

rebar. Using a sharpening stone, gives a result fast, so you won't have to wonder.

Check it out, Ben

Togba I disagree

I think it is a space rock. looks like It could be LA001 or 002 also heavily territorialized with a nice crust. chert or flint no. AzNuggetBob
