An Introduction to Michigan Geology
Vložit
- čas přidán 8. 07. 2024
- The geologic formations of Michigan span more than 3.5 billion years, from Precambrian rocks in the western Upper Peninsula to Paleozoic sedimentary rocks in the eastern Upper Peninsula and Lower Peninsula, followed by thick deposits of glacial drift from the Pleistocene. This video provides an overview of the geology of Michigan. We explore the types of rocks, how they were formed, where they can be found, and notable resources they provide.

I didn't Realize grand ledge was so unique! I'm for sure going to take a closer look at the ledges. Also it was really interesting to see how Michigan was formed. This video does a great job at explaining the process.
Thanks! Keep an eye out for our upcoming video all about visiting Grand Ledge.
Soon, there will be a new book on the geology of Michigan that will take the reader to 56 unique stops scattered across the state to see areas of geologic significance.
What book?!
@@michigangeologicalsurvey Can't say much more right now, but it should be available soon.
@@captpaul8827is it available now?!
This is a great summary of the geology of Michigan. I was able to take a field trip to the U.P. with a geology class and see the old, volcanic rocks that are present up there as well as take a tour of an operating copper mine. I thought it was very interesting that organisms such as gastropods and stromatolites were present during the Cambrian time.
This brings back memories. I loved being a student at WMU and working with the MGS.
We're happy to see a comment from a previous employee! We'll be sure to let John Yellich know :)
Great video. It was packed with information. Thanks 😊
I did not realize that Michigan is so sedimentary heavy! It’s so fascinating that Michigan has been shaped and influenced by water, via marine environments, inland seas, swamps, and glaciers, while today it is in the middle of the continent.
This is a great overview! It is really cool to see such a diverse environment changing through time.
Thank you for your insight and research!
An educational video of the Mid-Continent Rift, Keweenaw Fault and the copper rafted by glaciers during the last ice age would be informative.
Great video! It was really interesting to learn about the unique processes that formed the geology of Michigan, and the species/climate that used to be there.
I have an online business for pet rocks and I use lots of rocks that are round. Thank you for being around.
There are plenty of great rocks to collect around Michigan. Keep an eye out for our soon to be released video on rock-hounding around Michigan!
Wow neat, glad this information is available
Boy if that’s not a asteroid impact site I’d be shocked! It’s awfully similar looking to one!
The gypsum that you speak of was mined until about the year 2000 in the Grand Rapids area. I worked with a guy who was a blaster first in the mines by Butterworth (where there remain concerns about sinkholes due to the shallow nature of the mine) and then at the mine near East Paris street out by the airport until he was layed off when the mine closed.
I believe that one of the mines in the vicinity of the CSX rail yards is still used for document storage.
So the Jurassic beds were used economically and may include potentially mineable potash deposits around Mecosta county.
Still a good video so I will be leaving a thumbs up.
Awesome
Great overview! It doesn't seem very well known that Michigan has so much potential for natural gas storage
I like the star to show where MI is located for the different time periods, however I think the state outline would be better to show scale for how much of the state is submerged or where it is located. Good video overall.
O.K. Now, we need a You to do Minnesota please.
Very interesting and nicely presented. Thank you! I'm wondering if Michigan is part of the Superior craton?
I wonder how many iterations of ice ages it took to create the great lakes, as deep as they are. There have been many.
Interesting video, im no Randy Marsh so im not so smart with geology. But I remember knowing that because of the ice sheets, it exposed a lot of copper for native Americans to use and trade, essentially creating one of the earliest metal working civilizations. Also its native copper, i dont know how special that is in geology, but i love the pretty copper ores and malachites we get from the UP
Nice broad introduction to your state.
Maybe we’ll meet at Cosmic Summit! I’m from MI , St Clair, parents from Pt Huron and Marine City
Living in NC now down the way from Asheville 👍🏼
You know about info for the imlay channel. Going into oxford gravel pits?
What are your thoughts on a meteor impacting that area?
Tell me more about the Irish Hills area geology.
We can definitely add this to our list of future videos to make. Thank you for the suggestion!
If you really wonder why our state looks like that the circular formations check-out Antonio zamorio . I bet we connect with the Carolina bays ?.??..
I found a petrified turtle in a gravel pit in Brighton Mi, dont have it anymore though
What about gem stones where did they come from like yooperlite, and agates
We're working on a video about rockhounding that will have a bit more information on these! Keep an eye out, it will be posted soon
At 4.20 that’s the 12 Apostles in Australia, pretty sure that’s no where near Michigan.
Very good but to speedy, slow down and show more rocks-examples so Michigan citizens and others can be more familiar with what they see when hiking or just looking in their back yard.
Canadian shield.
It’s refreshing to see climate change being shown and the consequences explained in geological records after all climate change is currently being blamed on human activity. Folks, climate change is continuous wether humans are here or not. The planet is alive and continues to evolve.
As I’ve always said, but who listens?
Yea because humans were responcible for the ice shelf melting.... before humans and industrilizarion....
Yes, the earth’s climate has always changed. What is different now is the RATE OF CHANGE. Burning of fossil fuels (mostly) has altered the atmosphere unusually rapidly since the dawn of the Industrial Revolution. One of the downsides is that most species are unable to adapt to such rapid change.
@@scott5565Yep. Historically when the climate has radically changed in short time periods due to perturbations like meteor impacts we refer to the result as mass-extinction events. Take note.
Ok. Thats an impact crater . Looks just like the ones nasa makes in their lab.
Where's the gold?
UP
i freaking hate geology!
I jus wanna know where GOLD is in MICH.
Should we make a video on gold prospecting and deposits in Michigan? :)
MICHIGAN HAS GOOD COPPER MINES , BUT VERY LITTLE GOLD HERE
