Strontium (Sr) Elemental & Isotopic Behavior and Proxies | GEO GIRL

[@johndavidbaldwin3075]

Strontium is named after the village of Strontian on the coast of Loch Sunart in the Highlands of Scotland, West and slightly South of Fort William

[@richardrahl1001]

This was great! Ever since I was a child and did a study on Sr. Strontium (the corny jokes never end), Strontium has come up again and again in random things like nuclear physics and radiology. Such a fun element! Glad this is the first I found of your videos on these topics. Makes me excited for others. The benefits to archeology/anthropology and radiometric dating in geology is fascinating! Thanks for sharing!

[@Dractonis]

Yeah I found this vid looking up stuff for a final year Astrophysics module haha

[@stevengill1736]

Never occurred to me that strontium might show up in dental apatite! It's already fascinating to me because of the fluorine content - now there's strontium too, neat! Just as long as it isn't strontium 90! Isotopadelic baby! 😊

Great lecture! Also pigtails ❤

[@jackprier7727]

Yes I LOVE your exact cogent descriptions of these processes (re: atom sizes), and it helps that your voice is wonderfully lyrical--

[@junaidashraf2537]

Thank you so much, your videos helped alot

[@UsmanAli-yz5zc]

V.nice and informative

Thank you!

Thank you! This is exactly the video i was looking for :)

[@GEOGIRL]

You're welcome, I am so glad the video was helpful for you! :D

This video was strontiummy!

Hello still writing down notes here : )

[@GEOGIRL]

Yep, Geology is the study of 'Earth' and everything it contains! :)

[@gabeesp9654]

@@GEOGIRL yes I see I had to draw a lithospheric diagram however some terms can be questioned but I am going with the study if I make any sense ?

[@FaRosVPL]

So helpful! really well presented and summarized. thank you!

[@GEOGIRL]

Yay! No one ever comments on my Sr video, but it is one of my favs haha. Thanks for the support! So glad you found it helpful :D

woow you really saved me thank you..

Yay! So glad I could help you :D

[@p_er_man]

strontium video really helpful 👌👌Where is the barium isotope video? I went through the channel but couldn't find it?

[@lalitjoshi9379]

How the Sr isotope ratios from human teeth determining the where that person grew up, what they ate, they lived? Please elaborate?

[@GEOGIRL]

Great question! Since I am not an anthropologist that works in this field, I didn't feel comfortable speaking on this, but here is a great video to answer your question: kzbin.info/www/bejne/qKOne2uInpijjs0 (it's only 3 minutes!) Maybe in the future I will do some more research and make another video all about this aspect of Sr isotopes, it is very interesting! :D

[@smileydaisy-qt3md]

Can you please make one on Sm Nd as well😁

[@davidchurch3472]

If oceanic crust rocks are always reforming and recycling, they should contain the older strontium that came from the previous crust they were recycled from, so the strontium isotope ratios should not change with recycling, but should be same atoms as previous crust, only changing with time - unless there is input from external source like C14 is from air?

[@oliverweeweepie3132]

[@JeffPittman]

Very interesting! Specifically the 706 line, which is near me (Eastern Washington / Northern Idaho). Would love to know if there are geological or landscape changes that I could watch for when traveling near the line. Additionally, I work for a gold mining company, and would be interested if the 706 line has an effect on mineral deposits.

[@stevengill1736]

What about something like strontium sulfate which has three elements with isotopic ratios???

[@barbaradurfee645]

OK, time to actually MAKE those other isotope videos

[@GEOGIRL]

Lol calm down! I am getting to it 😅

[@smileydaisy-qt3md]

I think this is your mom. How cool!

[@UsmanAli-yz5zc]

What is your research field???

[@GEOGIRL]

Marine biogeochemistry (reconstructing paleoceanographic biogeochemical conditions using trace metal signatures in the rock record) :)

You are great you, will publish this in my telegram geology chanel

Thanks! So glad you enjoyed this video (it's underappreciated in my opinion) ;)

[@Hey_Samhere.1406]

Hii love from India actually I want to know about the basic strontium should I have.....

[@delhatton]

well done

[@cherryblossominternational3036]

Hey! it was an excellent piece of info. Can you make a video on how Nd and Sr isotopes could be used to unravel crustal evolution process and geodyanmics of a particular geologic area.

[@GEOGIRL]

Thanks so much, so glad you appreciated this video. And thanks for the suggestion! I will try to get some information on that topic and see if I can make a future video ;D

[@cherryblossominternational3036]

@@GEOGIRL Will be eagerly waiting for that video. Hope you come up with it soon. Thank you
