Stable & Radiogenic Isotopes in Igneous Petrology- Geochronology & Isotope Tracers- #8 | GEO GIRL

[@robertanderson809]

At 76 I find I'm learning again. Great clarity and scope. New lease on life. Thank you. Geology is so fundamental and so neglected in my 60's college years.

[@asmagufran5301]

you are the best teacher of geology for me. your videos always always help me out. thank you doing soo much hard work for us.

[@GEOGIRL]

Thank you so much for this comment, it made my day ;) I am so glad my videos have been helpful for you

[@gneissnicebaby]

"Because rocks are FREAKING OLD!" 😂 Idk why but that made me chuckle. Anyway, thank you so much for making this channel! It's so helpful for review! My professors lectures are an hour to 3.5 hours long and idk about you but it's really hard to pay attention and stay engaged for that long! So for that reason, I love the condensed and concise way you communicate various topics. Thank you!

[@GEOGIRL]

So glad you find my videos helpful! That is actually one of the major reasons I started my channel becuase I wanted to break these topics up into more digestable chunks for students since so much is discussed after the first half hour of a typical lecture that is just in one ear and out the other because WHO IN THEIR RIGHT MIND can actively listen to a lecture for over THREE HOURS?! lol I mean I thought 1 hour lectures were bad, but 3.5?! That's crazy, I am so sorry hahaha! Anyway, thanks so much for the kind words and support, I hope you continue to find my videos helpful and occasionally funny ;)

[@gneissnicebaby]

@@GEOGIRL of course! And I definitely will! This is at least the 2nd time your videos have helped solidify my understanding. Plus, wednesday is my first metamorphic petrology lab so I know your series of videos on that will be super helpful! So thanks again and I'll be sure to share your videos with my classmates who come to me with questions 😂

Waking up to the notification that you have uploaded a new video, my day is off to a great start so thank you for that. 😊👍 About thirty minutes later, I’m already feeling more educated. I also hope you’re having a great day, thanks for another interesting and educational video, I look forward to seeing and learning more. 😉❤️

[@GEOGIRL]

Stoppp, you are too sweet 😂😍 I feel so undeserving of your incredibly kind comments, thank YOU!!!

[@Smilo-the-Sabertooth]

@@GEOGIRL You’re very welcome. 😉👍 I think you’re very deserving of kind comments. 😊❤️

[@bishnumishra8224]

I like your presentation. Firstly, you are an eloquent speaker. That signifies you understand the topic by heart and speak your mind. Secondly, the graphics you use in your presentation is of a high standard, meaning, it is to the point, and explain everything written on that particular slide. Now I wonder if you can help me out in finding or preparing such graphics as you do. Any lead on that matter is highly appreciated.

[@GEOGIRL]

Wow, thank you so much, I am so honored that you think I am that good ;) I make all my lectures on powerpoint, so first things first is to ask, do you have access to powerpoint or do you use a different software? For my figures and images, I just google appropriate search terms for the topic on that slide and then pick relevant figures (preferably from peer-reviewed journals but many times that is not an option). Then, I paste them into my powerpoint presentation and edit them if I have to. Sometimes I crop them or put little colored squares over portions of them to simplify them if they are too busy, but this is where the software comes into play. I have basically become a pro at powerpoint haha, so that is my best advice is to become a pro at a software that allows you to edit the way powerpoint does (make slides, copy & paste images, crop, resize, reshape, color, etc.).

Hi @GEO GIRL! Thank you so much for your videos! I love listening to them and looking at your slides. Would you be willing to make a video on how you create your slides and prepare for a presentation? Thanks!

Yesterday I am reading geochemistry from JD winter and I was like confuse ungabunga 😀😀😀

[@velikerimov9703]

Geogirl PLEASEE, Can you add russian to the subtitle in youtube's settings, we can't make automatic language selection when looking from the phone.

[@GEOGIRL]

I went into the settings to see if I could add them, but if I add them manually I have to know Russian, and unfortunately I don't know Russian... Do you know of another way I can add them??

[@samakshgupta8750]

Thank you for this lecture❤

[@GEOGIRL]

Of course!

[@dasilvasoares2301]

Due to the rare existence of radioactive elements in basaltic volcanic rock, it is very difficult to identify the absolute age of that type of rock. in this situation what type of dating method do you recommend to define the age of the rock accurately?

[@GEOGIRL]

Actually basalts are one of the rock types that contain plenty of radioactive isotopes for us to use to date them :D The dating techniques commonly used for basalts include: Potassium-Argon (K-Ar) Dating, Argon-Argon (Ar-Ar) Dating, Uranium-Lead (U-Pb) Dating, Rubidium-Strontium (Rb-Sr) Dating, & Samarium-Neodymium (Sm-Nd) Dating. Basalts can also be dated using paleomagnetic dating (becasue basalts can preserve the Earth's magnetic field at the time of their formation, which we can then correlate with known paleomagnetic data) Hope that helps! ;)

[@hafizhelmi3139]

Can you cover topics about petroleum geology and geophysics becoz I'm taking this course in this semester

[@ourtinytale7520]

Isotopic equilibrium? I thought an isotope will decay and emit subparticles and remain in its new state? Unless during beta decay neighboring isotopes will absorbs these subparticles, electrons and antineutrinos, and change proton count. Help me understand.

[@GEOGIRL]

Stable isotopes do not decay. Only radioactive isotopes decay. So, stable isotopes fractionate (most often due to mass differences) in the environment until they reach equilibrium. Hope that helps, I have a bunch of videos about stable isotopes if you still want to know more ;)

Thanks for ur guidance ☺️👍

I am doing B. Sc (Geology) After that plz give me suggestions so that I can study forward and become a better person for my self 😊

[@RonJohn63]

"Isotope" comes from the Greek words "same place". IOW, isotopes are at the _same place_ in the periodic table as elements.

Stable and Radiogenic isotopes in sediments?

[@GEOGIRL]

Hi there, not sure if this was a question or statement haha, but if you do have any questions, I would be happy to attempt to answer them, just let me know by responding to this comment if you do ;)

[@satyajitmajumder6959]

@@GEOGIRL oh shit I made an incomplete question. 😂 Is there any video related to Stable nad Radiogenic isotopes in sediments in your channel?

[@GEOGIRL]

@@satyajitmajumder6959 Haha! No problem. I have many videos about stable isotopes in sediments on my channel, but they are broken up into isotope systems: oxygen isotopes (kzbin.info/www/bejne/eWnEYZanotGlatE) carbon isotopes (kzbin.info/www/bejne/i4m6mKaZpsdgmdk), sulfur isotopes (kzbin.info/www/bejne/gmSyp41qibSmrM0), strontium isotopes (kzbin.info/www/bejne/maScgHiQfc9pmJY), and I also talk about radiogenic isotopes in m absolute dating video: kzbin.info/www/bejne/fInRYp6Xg611e8k. But I plan to talk much more about stable isotopes in future videos, such as Mo isotopes, Ba isotopes, V isotopes, Tl isotopes H isotopes, I just haven't quite gotten to those yet, and if there are any other isotope systems you'd like me to talk about, let me know and I'd be happy to! Thanks ;)
