Great video overall. Very informative. As a geology professor (specialty in cosmochemistry) may I give one item of constructive criticism: your classification of meteorites is not up to date. Because of the differing origins of the "stony" meteorites, meteorites are better classified as primitive or igneous/differentiated. Differentiated means that the body (planet, asteroid, etc.) got hot enough to completely melt and stratify into a core, mantle and crust. The crust was formed from igneous processes (melted rock). For example, "stony" meteorites contain chondrites (primitive), achondrites (igneous), lunar meteorites (igneous), SNC (martian) meteorites (igneous). These all originate from very different bodies and have experienced very different histories. All of the "irons" and "stony irons" are from differentiated bodies; they are of igneous origin. Keep up the good work. I learned a lot about meteorites found in Michigan. Thanks!
Cosmochemistry, that is unusual. Where are you with the Carolina Bays, beaver tails, fish fins, Aeolian, gas bubbles, or secondary impacts? What about the 'fluffy nothing comet' that was the progenitor of The Taurid Meteor Stream, our most recent, and the causation of The Ages of Man? I live in what I believe is a complex crater, sort of alike elliptical water ripples frozen in time.
Books ! Recommend books for me , on metiorites ,with pictures , and at least 1000 pages...new data - plz! -who ,who! Whoms! The leaders in the field? ...do you cross country ski ? I've been cutting trail for 3 years... Plz recommend ...a fat book - of all the things we know for sure , ..
I found something while metal detecting about 20 years ago. It's not magnetic though. I found and kept it while digging another target. It looks burnt or melted and rusty colored. I could send some pics thru email if anyone is interested in seeing it. It's from northeast Hillsdale county.
Saw one explode above Chatham around 1974, we were at the MSU extension for a conference and during lunch break my father and I were in the truck in the parking lot having a sandwich, it was traveling from south to north. Good luck finding it there's a lot of trees there.
I have what MIGHT be a small meteorite. It’s dark and smooth with dimples, it’s not porous, it’s magnetic…and I found it up near traverse city. It doesn’t look like any rock I’ve ever seen, and it doesn’t look like slag, which I’ve seen quite often. I always wonder what it is. One day I’ll probably send it in to U of M or something I guess!
We also have another video on ways to identify a meteorite! Take a look and if you're still not sure there are resources linked in the video for you to send it off for testing. th-cam.com/video/rUQbcd4XHsY/w-d-xo.html
Hi , I might be able to help , I've spent the last 3 years getting to know metiorites , 5 years of college geology , ..I need to see the sample - I need it's density: ...your dimple's. Are they " thumb" sized, is the outside , burnt black - any flow marks?..contraction fractures: ..odds are you do not have a metiorites : but I routinely ' make a chart ' ...how many attributes - shared with. ' known ' metiorites...if you score six of a possible 8 attributes , we can consider - spending time an money to find out for sure ; ...
I seen where green one hit in Michigan. I'm not kidding. I'll show you where if you promis me finders fee.. I watched it break up and turn to like 5 to 7.
saw the one coming down they found near traverse city. bright green, and lit up the whole forest
Thanks for sharing this cool information

Yeah I dropped that when I was a kid, and would really appreciate having it back. Is it part of my childhood memories.
😂😂
I have one I found behind our family cottage Chippewa Lake 22 yaers ago when I was 13yo.
I either found a nice lode stone or a meteorite. It's around 3 pounds, it's solid iron from what I can tell. Who would I contact to have it looked at?
That's interesting. Thanks

"Tom Hagan" hmmm maybe it wasn't a meteor but his friend "Sonny" riddled with lead?

You should figure out what it *is not* if you can’t tell what *it is*. Sometimes that can be enough

@@michigangeologicalsurvey Thank you will watch it now!

I'm pretty certain there's one embedded in the bottom of our swimming pool.
Do you know why asteroids are tastier moon rocks?
Because they're meteor!
