The one shown near the end which was described like candy corn really resembles Thomsonite, I think it has a bit of chatoyancy from the fibrous structure, agate or chalcedony doesnt normally have that effect

I appreciate your classes and love how I'm still learning about the world around us. Thank y ou.

Good teaching.

I appreciate your thorough description and distinction between other types of puddingstone and the "tillite?". Thank you for creating this informative video!

It looks similar to Thomsonite from Minnesota but just not as beautiful, colorful and well formed. It is hard to find good stuff in Michigan vs Minnesota. I will try to find some one of the trips up there this year. I notice in another video like a recap after this you had not found more so I'm not sure if that place only had a little bit or not. Stuff in minnesota is way better.

Thank you for the chemistry behind the difference.

So is a fossilized bone with calcite around it considered banded calcedony? The calcite does glow under uv light.

Subscribed! Thank you!

Sticla?

Heat and pressure are easy when there is an electric discharge present. I love your videos by the way, just found you today watching Quartz vs Calcedony vs Chert vs Jasper. Excellent explanations!

Thank you for clarifying! It seemed that the more I studied, the more questions I had. Your explanations are so easy to understand that I can now see a more logical path to follow.

So where do dendritic/moss agates fit in, since they don't have banding? This is the first time I've heard of banding being a defining feature of agates and I'm confused...

My son found a wierd heavy beautiful rock about 150lbs my husband broke it open with a 30lbs weight and it has crystals in it...would love to get in contact to see if u could help us identify it

Didn't explain much I'm just as confused as before and jasper comes in many different color

Excellent, sir! "Clears" up a lot of my confusion.

Very good thank you so much. I needed this explanation

Thankyou!

But what about moss agates ?

Beautiful! Thank you. Do you have any field trip guide or other resources that might show where I can collect or buy a cobble-sized specimen? Beach or river-rounded? I did find some banded Iron formation with less obvious layering at a rock shop in the Keweenaw a few years ago. Look forward to viewing your other videos.

🎉thank you! Now I have been educated

I have some interesting rocks I would like you or someone who is familiar in the field to look at

While many of these generalizations might be true in Michigan, they do not hold true other places. What about all the other jaspers in the world? They come in many colors. Montana agates don't usually have banding. Jasper is not red chert. Every book I have puts jasper in the mineral section next to quartz and chalcedony and put chert in sedimentary rock sections.

“Let’s go get that milkshake” should be your sign off for your videos 😂 I felt that in my soul, rockhounding is real work

WOW! This is an eye opener! I've seen plenty of Michigan stones people call "Puddingstones" and none were pure white like this example. Now I wonder if I've ever held/seen a real one.

Hello, stay alive. It's great. I like this video. What kind of stone does it look like? Tell me its name❤

They definitely crush it up for gravel. We stayed at an Airbnb and the whole long driveway was Kona Dolomite! I was in heaven! 🥰😂

Your explanation approach is great thanks, and people who prioritize space for their geologic and chemical wonders are my people. Thanks for sharing your knowledge.

I live in western Colorado btw. Incredible geology here and the section of river 1/4 mi from home flooded... Agate, chalcedony, Chert of endless designs...and Jasper's to drool over. Might be opals and fossils jump up and bite ya around here too. I'm entirely lost to my rock obsession. Gone. Oh yeah geodes. And obsidian. And gold and copper ore.. and fluorite and quarts and mica boulders and rolling dolomite hills and all kinds of crazy wonderfully diverse treasure troves. May have gotten to see the "Titana-boa", exhibit a while back when we were graced with it's extended visit. 😀🐍

Do you have a place for discussion?

OMG... I'm surprised I found this channel and it's not my birthday!!!😲😆 Thanks!!!

Thanks so much, that was very clear 😊

I love you dude, so cutely scientific. I’m preparing to help my 5 yr old great grandson become the rock hound he was born to be, he loves rocks, like me😊

Thanks for the info, Rob would have that shinning like a diamond

Good day.Sir can you identify my stone please.thanks...
