Hi Shimmi99

Strictly speaking, that is a breccia and not a conglomerate. The geological difference is that conglomerates are exclusively sedimentary and the clasts within the matrix are largely rounded or sub-rounded. Breccias can be sedimentary, tectonic, landslide/collapse/impact-related or volcanic/igneous in origin and the clasts within the matrix are mainly angular.

That particular clast with the concentric rings is interesting. The most commonly seen mineral with that kind of structure is ā€˜beekiteā€™, which is a form of microcrystalline quartz that most usually arises by silica replacement of carbonate minerals during fossilizationā€¦ especially for things like corals.

Beekite can be pretty much any colour, but is usually...

I'm gonna say it's more of conglomerate specimen than breccia. I'm thinking a fossil of some type got into the mix of various materials before it came to be all cemented into a solid piece. A rock that has many stories to tell, I would say it is.

Beekite can be pretty much any colour, but is usually paler/browner than in your specimen. No easy way to be sure from your pictures, but that would be my guess.

Your very welcome, but I was wrong about it being a conglomerate, as it is a breccia as Red-Coat points out. However I do have an interesting piece I consider a conglomerate with copper oxide infused with in it. I picked it up at a copper mine located in what's called the Lisbon Valley in Utah, when I made a visit to the mines Drill and Blast forman.

Several of those look to be serpentinites, for which brecciation is not uncommon.
Obsidian? Found this in forested area no civilization or industry for 80miles light passes threw these.

Light passes threw all besides the sedimentary (light red to dark red) and small bright red specks maybe 2-3 specks
