Michigan Geology | The Michigan Basin 

I hope this video showing up on my home page feed is a sign that my algorithm is healing

RU-vid surfaced this my recommendations because of my interest in geology. Very concise, very informative, very information rich.

The runescape music tho

Very very well done. No hyperbole or overwhelming musi either.

Great video, the salt mines here south of Detroit im told go down a thousand of feet, currently they take up 1,500 aches and there is 70 trillion tons more, if they where ever ruptured and let the Detroit river in it would have some serious effects on the surface. Ive lived here my entire life and can't believe i just now learning this, amazing.

Great info. As a Michigan resident I appreciate this and always wondered about what rocks these are in the UP

Wonderful and concise. Quick overview.

Can you talk about of the high points in lower Michigan like Bald mountain? How did they get so high compared to the rest of the Detroit area?

Thanks for posting this basic and informative video on Michigan geology. And though basic the geology history is quite complex. I like the initial explanation of the formation the basin resulting from the extensional forces creating the upwelling of magma. And this led to the geologic principle of isostatic equilibrium. (Well depicted in the graph and explained.) Then the part about the two causes leading to the formation of the basin. 1) The 3 orogeny events which led to the Appalachian formation and 2) the oceanic intrusions which laid down the paleozoic sedinents. As described the Paleozoic layers Cambrian through Pennsylvanian mostly lie below the surface layer of the more recent Pleistocene period sediments. The ancient ocean intrusions of marine habitat like much of North America explains this layering of these Paleozoic sediments. And then the later north south river deposits explain the gradual subsidence of these older sediment layers. At least that is my rephrasing of the content of this video which I wanted to do for my own purposes to frame the general history of Michigan geology.

I guess the Petoskey stones are the left over remains from one or more of those ocean advances?

Very good content. The presenter spoke waaay to fast. I had to slow the sound down to .75 for all of the presentation and down to .50 for the last few minutes. Overall worth the effort.

What about the salt bed underneath Detroit, that's been mined for more than a century?

Podolski stones… I learned something new today.👍

Can anyone tell me why the geologic law of original horizontality doesn't apply to the Michigan Basin? "The principle of original horizontality states that layers of sediment are originally deposited horizontally under the action of gravity."

I found some silurian tabulate coral when digging out my pool in the grand rapids area. Went extinct 480 million yrs ago

Draw a great circle line from the center the Chixulub crater (the Gulf of Mexico is a perfect circle) to the center of the eastern shore of the Hudson Bay (a perfect circle)...

Sure that's not a meteor crater from a billion year ago?

My friends uncle owned some land next to a gravel pit on the St.Clair ,Sanilac border .Some of his land was excavated and had a huge pond. I found tones of plant fossils there mixed in with the gravel around the shore. There was just so much i couldn't believe it.

Anyone else notice the background music is from Runescape?

Love it. Will be sharing this with my students.

nice video and overview

Strange, I kept waiting for the narrator to say, "That we know of!"

Excellent video!

An excellent presentation. Such a massive accumulation of carbonate and carbonaceous rocks must have been formed from mantle-derived methane.

You forgot the many underground Tunnels for human trafficking all the way up through Canada ☠️☠️☠️☠️☠️☠️

The upper deposits of competent sedimentary rock was able to defeat the erosive effects of numerous glacial age transgressions. Why were the only breached across the Saginaw Bay Area?

What about the stone hedges the professor from western Michigan University found under the water in Traverse Bay? Did these changes happen well before these during, or after?

...rift... No wonder why we get earthquakes from time to time. Sure, they're not Cali quakes, but still. Shouldn't be feeling quakes like that.

I'm so glad the oceans filled up the portage canal with beautiful rocks so Michigan Tech students can drink beer by them

Insightful video. Great information about my home state.

So, what would happen in SW Michigan should New Madrid finally lets loose? Do the red beds shake into quicksand?

This is my first experience with your channel. What a find! I love it. Thank you.

The background music is way too loud to understand what is being said :( I was very excited about the content but was unable to listen to it.

I live in Ontario and I've always thought the story doesn't really add up to me. The great lakes basin always struck me as a impact crater but the more I learn about the Michigan Basin it does seem as though that would explain much of what I see or don't see here in Ontario. Like where is all the glacial till? I've seen random boulders that were left by the ice but nothing smaller. Even on the Canadian Shield the surfaces are smooth as glass and hardly any till to be found. I understand moraines are formed by most of the till being carried forward in succession but idk it just seems like if there was 2km of glacial ice above me 10kya and it melted that I would see a lot more of it. Unless it melted rather fast and carried away the smaller debris. This is a great video that disputes all of what I thought and it makes a strong case. What an amazing time to be alive thank you for the video.

It definitely looks like a ancient asteroid impact site!!!

Is this background music from osrs?

No

Basic conclusion, Michigan is one big sink hole..

BAY-salt? Sounds AI narrated.

*(**3:05**)* - Spongebob makes an appearance. XD

who up michiganing they basin rn

Lots of good information here, but the pace is too fast. Fast talking and flash slides is not conducive to learning. Why the rush?

Great job! Love the music too. Very easy to follow and understand as a layperson.

It's an ancient impact crater. I've known this for years and years, and was backed up by a geology professor from the University of Chicago.

Is that runescape music I hear?

Makes sense, like Sudbury in Canada. Other impacts in the general area as well.

how do you get those dates

awesome video!

Terrific content as usual, thanks!

Great catch by the mitt of Michigan.

Sure! 🥴

Thanks. I enjoyed this.

this is exactly what i was looking for! A smoothly edited video about the basin in a short but well detailed video. Definitely subscribing for more great lake geo history

So the dispute about if the rock layer actually is Jurassic or not, suggests no dinosaur fossils have been found in Michigan

CAN WE GET A DEPTH CHECK ON THE MICHIGAN BASIN??? HOW BIG WOULD THE STICK HAVE TO BE??? THIS IS INCREDIBLE!!! HOLY CANNOLI

Needed this

Thanks

👍👍👍

Sure looks like a meteroid hit there and splashed the iron from michigan and the nickel from the meteroid forward toward Sudbury where they mine that nickel, since nickel isnt commonly found on earth. But, what do i know?

Exceptional. Concise, complete - and clear.

How come there is no sign of ancient human life in Michigan? After all its surrounded by fresh water. How is it that no ancient human life is found here. Or perhaps whatever ancient life that did exist got destroyed by those who write history.

Greetings! Thanks for your educational effort but please remember you know lots about geology and not music so get rid of it as it degrades the professionalism of your work! Best of luck!

The first thing I thought of when I learned about Michigan geology was an impact crater

What? Why doesn't the gravity anomaly show over st Ignace, the mystery spot is there! 😂

Sorry, content seemed great, but couldn't get through more than 2 minutes because the background music was so annoying and distracting. Why did you ruin this video with background music? Do you just have to be like everyone else?

What a joke!

Air burst impact 10500 BC , Lake Michigan and Lake Huron is horse shoe crater
