RockandFound Posted December 16, 2021 Share Posted December 16, 2021 Hmm not sure if it was cleaned up a lot more it would help narrow it down better. Quote Link to comment Share on other sites More sharing options...
Red_desert Posted December 17, 2021 Share Posted December 17, 2021 Is inside of rock hard like agate? Or any tiny crystals visible in holes? There is river rock with water worn holes, often can go through the stone to other side. Try Google holey stone. That was a popular 90s New Age stone.

Red_desert Posted December 17, 2021 Share Posted December 17, 2021 (edited) Here is a New Age link. But normally, holey stones don't have so many holes as your rock.

Red_desert Posted December 17, 2021 Share Posted December 17, 2021 (edited) Natural gas bubbles in rock can look pitted also (at least I was told that). Edited December 17, 2021 by Red_desert Quote Link to comment Share on other sites More sharing options...
chrisski Posted December 17, 2021 Share Posted December 17, 2021 Really looks like basalt rock. These are my results for “rounded basalt bubbled.” I find a lot of rock like that in the desert, but its jagged. Thrown in a river for a few years, it’d turn rounded just like you saw. My guess is your rock split would look like some of these. Quote Link to comment Share on other sites More sharing options...
Bedrock Bob Posted December 17, 2021 Share Posted December 17, 2021 It could be a water worn agate. Those don't look like the spherical gas bubbles in basalt. It looks like a wild, folded agate that has been worn down. The hardness will tell the tale. If it is hard and glassy inside it is agate. If it is porous and like fine mortar it is probably basalt. You could rub a spot with sandpaper or a file and see pretty quick. Agate will leave a white powder and be hard to grind. Basalt will be easy(er) to grind and leave a powder the same color as the rock. Quote Link to comment Share on other sites More sharing options...

4meter Posted December 19, 2021 Share Posted December 19, 2021 Looks like a iron stained piece of quarts to me. The "dimples" may be the result of dissolution of other minerals, likely feldspars, as the sample was weathered by its time in the river. To tell what it is, best to have the sample cleaned of the dirt, and maybe grind small area to show the unweather material underneath.
