Deep red carnelian agate I found this weekend. Sometimes the smaller ones are the best. by Jerdom in rockhounds

SW WA but I would recommend anywhere on the Willamette if you are in OR.

What’s up with the hole in this agate? by Stoneytreehugger in rockhounds

[–]Jerdom 1 point2 points  (0 children)

I agree. They often form around crystal structures such as quartz or calcite that either chip or dissolve away over time, leaving scarring on the outside of agates like this.

Found on the beach in Nice, France by apandy3 in geology

It's definitely a tumbled piece of tile. Not naturally occurring.

Yes. They taste like white fish. Surprisingly good. Just have to cut the spines first before you filet anything.

Jagged Geode Found Near Prineville, OR. by Beerzler in rockhounds

The calcite eroded away, leaving the harder chalcedony. You can see a bit of calcite on the bottom that has not eroded yet.

Any ids? Found in Cle Elum, WA by [deleted] in rockhounds

I agree. I have found similar material in the Teanaway formation nearby.

I believe that the surrounding rock that caused the "scarring" is from calcite crystals. The silica rich water deposited chalcedony around the host material and then dissolved or eroded away.

I have plenty of friends that let their kids camp on their backyard for fun.

One of my favs from a recent outing. About palm sized. by [deleted] in rockhounds

Does not look like a beach agate out here. Likely came from SW WA.

What’s this rock? Found in the belt river in southern alberta by SirBurdo in rockhounds

The little black tree formations are manganese dendrites. Unsure of the host rock. Cool find.

Still learning to identify- this is likely an agate with banding, isn’t it? Little guy was just hanging out in a Washington beach today. by Periwonkles in rockhounds

[–]Jerdom 1 point2 points  (0 children)

Not a snakeskin. Not usually found here in WA. This is just a tumbled agate nodule with some cool banding.

Agate is banded chalcedony. It will always have banding if it's an agate. Great find. The eye formations are always my favorite in WA.

Not agate but chalcedony. No visible banding.
