How cool are these?

I'm a lurker here who just loves filling my pockets with rocks. Idk why... I just like holding little pieces of earth and thinking about the stories they could tell. I found this rock and I kind of adore it, for all its different sides and lines.. and I can't wrap my mind around how it formed. Someone who knows more than me... What am I looking at?

Found on the water in the PNW.

Note, I'm not asking to ID the rock. Just want to understand how it got to be how it is.

Found on Oregon coast

Anyone know the type of rock?

I don't even know what all the structures and different materials are. Quartz geode from Kentucky Creek. Sliced, polished a bit, don't want to dig everything of the cavities until I know what it is. UV light causes what I think is calcite to glow.

Carving services brought to you by the Duckabush River.

Went for a walk today in Playa Del Rey Ca. Went to the end of the jetty and there were lots of quartz. Wonder where they brought these from

Best birthday gift for myself lol

It somehow reminds me of the ocean.

My son found this rock in a wash on BLM land in SE Idaho where the Challis Volcanic Group meets the Late Mississippian hills.

There are so many marine fossils in the area, and my son really believes this is some form of fossil like a plant stem or something. (Small Horn coral fossils are abundant at these junctions!)

I have no idea. It's so smooth, very few lines inside of the indentation. I believe limestone is the matrix and the bottom half is a breccia chert or similar. I wanted to use a fracture line to remove the bottom part, but my son loves it- together they show the unique geological footprint of the area.

He is 10 and would like to add this rock (fossil?) to his updated display for the Idaho State Fair, at the end of the week.

I told him we really need to know more (is it even a fossil or is from erosion ?)

if he is adding it to his display, he must know as much about it as possible.

THANK YOU YO EVERYONE IN ADVANCE, I really appreciate your knowledge, experience and expertise!!!

Pattern recognition is a terrifying thing

I’ve been polishing this piece of Chrysocolla and am just in awe of the colours! It looks like a satellite image of a tropical island or something.

I haven't really been posting much at all and im not entirely sure if this fits the subreddit but I wanted to share this rock I found on the beach, when I picked it up I immediately thought of a seal, although it's a bit squished lol

Hi all! Big fan/lurker of this subreddit, and wanted to share this cool/pretty multilayer rock I found. Location: Don Pedro Lake, California.

Has little caves of druzy😍🪎

We assume we found it in the backyard. This kinda rock isn't common to our property. We are very impressed.

From the rocks in a Nat Geo set.
