What type of rock?

[rock]

Every once in a while I find this type of rock. It isnt flaky at all and might be marble (maybe). I do find white quartz in the area if that helps with the ID on it and its redish brown. Found in N Ga near the mountains. Thank you, rock

Have you thought of rhyolite? It is difficult to even guess due to the wetted surface. It hides the lustre of the rock.

Looks like some kind of jasper.

I havent washed it yet. I will take some dry pics of it tomorrow after I wash it. Might be a type of Chert. There is many types of chert here. Thanks

Ok I took some dry pictures of it. Not as pretty when dry. I like red color stones and always wondered what this was. I think this arrowhead is made from the same material. Thanks, rock

Still leaning towards Rhyolite, IMO.

Thank you it just might be.

One thing I've learn while on my travels, is that if the stone is left out in the weather or sunlight.. it can chage colors from dark to light etc.. The first few images I first thought it was of a Quartz based stone whcih had been left out in the stream, picking up mud, sunlight etc.. thus changing its color to the darker colors in your images above.. I still think its quartz.. but it could even be aventurine..

Thank you and I will check out that last one you said it might be. Could be quartzite I guess. I usually find them already made into Artifacts and always wondered what the stone looked like before they were altered. Thanks, rock

Quartzite tends to have a more greasy looking surface. Since its composed mainly of quartz.
If you like I can get some pics? Should have some around here.

While rhyolite also contains a lot of quartz, it is in a much finer grain size since its a rock formed from lava.
It's a, well, quite variable looking stone. Should have some of that around, to.

In natural form it would be nice to see.

İt seems red aventurıne quartz.

 

[rock]

I looked up that name aventurine and it showed some polished stones in green and blue. Really nice looking stone when it is finished. Could I polish this and make jewelry out of it? Maybe break some small pieces off of it?

Yes you can polısh and make jewelry,hardnes 7.

 

[rock]

That is a nice looking stone after it is polished. Thank you T M for your time on this.

Sorry, I forgot about the quartzite pics. Will get to that later.
It does IMO not look like red aventurine, there are no reddish mica flakes in there, or am I mistaking..?

No the stone is red but the flakes are silver it looks like.

hey- could you post pics of a flake or thin piece- held to the light? Everyone's really leaning to rhyolite, but I wonder if it's actually a 'Georgia rock'. Because of the light/wet surface, I nearly jumped to a quartzite- and I thought hixton (knowing that there's no way in hell it really could be unless someone traveled too far with something not worth the distance- especially when you have excellent knappable stone in GA). Your point looks so dull and flat (matte) in comaprison to the raw sample. Raw sample (wet and dry) look/appear granualr. Point doesn't. Looks more like either tired rhyolite or not-so-great chert (good chert being a rarity in your state). How does it crush? what is its weight? Can you grind down one side to see what a smoother surface looks like?
Thanks for showing and getting me thinking.

It seems too dark for ryholite. The bands of color in it make me think sedimentary. And it's somewhat coarse-grained...maybe a quartzose sandstone.

Thanks for everyones thoughts on it. I dont intend on breaking it though. It has been this way for hundreds of yrs and is going to stay that way. I enjoy rocks and artifacts just the way they were made. I leave them and dont alter them at all. Thanks, rock
