Thank you very much. I will complete all the loops of mineralogy&petrology and sedimentology, it gives so much in these videos. YOu are the best, love from Mongolia.
As a geo major your videos are my favorite to watch when reviewing for an exam or learning more about a complicated topic. Keep up the great work, we all apprecitate it! :)))
So glad to hear that! It really validates that I am doing what I set out to do (I mean I started the channel because I wished there were more geo topics covered on TH-cam when I was studying for finals! haha) So thank you so much for letting me know ;) And BEST OF LUCK with you exams!
I know I’m commenting a little late but I still watched the video and I still learned a lot. Fantastic video as always, keep it up with the great work. I look forward to learning more. 😊❤️😉👍
Thank you so much for this video, very well put together! I am about to start doing research with a professor on mantle sources, basalts, and meteorites. I graduated two years ago and it was great to get this as a refresher to catch me up to speed on things. You help me understand these topics more than others lol. They don’t seem overwhelming which I tend to feel at times with school. Will definitely watch more of your videos!! ☺️☺️☺️
So glad to hear that you have found my videos helpful for catching up on things! best of luck on your upcoming research! :D And keep me posted if you publish anything, I'd love to read it ;)
Thank you mam.....awesome presentation Question.1: Is mantle rocks are metamorphic or igneous pls explain in a broader picture Question 2: what is the extent of asthenosphere can it extend up to outer core
Thanks so much! Answer 1: Mantle rock is igneous, lherzolite to be specific. Lherzolite is an ultramafic igneous rock. I am not sure how to describe this in more detail, so let me know if this answers your question, or if you have more questions. I would be happy to try and answer any more questions you have ;) Answer 2: No, the asthenosphere does not extend to the outer core. The asthenosphere lies just below the lithosphere and is the means by which lithospheric plates move (plate tectonics). The asthenosphere extends downward (or center-ward) to the transition zone (or middle mantle, as I call it), which then meets the lower mantle, which then extends all the way down to the outer core. Hope this helps! :)
Thank u mam......... Mam sometimes when a plate subducting more or less vertically it can extend beyond the Lower Mantle up to 'd' layer so may be plate movement up to there that's why I am thinking extant of asthenosphere up to outer core..... Hoping it will help to understand my question
Of course! I finished putting subtitles on about 90 out of 100 videos on my channel because there are some odd ones out that for some reason are giving me error messages when I try to add subtitles (even just English ones), so I am trying to fix those, but for the most part, my channel is now subtitled in Russian! :D Thanks for your support, I am so glad you love my videos enough to fully understand what I am saying. It means so much to me! I will be working on fixing the troublesome videos for the next week or so, but I'll let you know when they're all finished :)
@@GEOGIRL Thank you, I gave you a lot of trouble, believe me, I love your videos too, I watch them eagerly when I find time, I love your channel a lot.😊
Unfortunately, no. It's funny because I was just talking to some geology friends the other day about movies that make geologically impossible things seem possible and 'journey to the center of the earth' is for sure a pet peeve for geoscientists hahaha! However, on a more practical note, I think your question is still valid because I do believe that, in a way, we will be able to 'travel' to earth's core and kind of already have by way of seismic waves! Kind of like how we map the structure of the mantle, we can do the same with the core via seismic wave velocity measurements. For example, our magnetosphere is not the only way we know the outer core is liquid. We can actually prove it by sending two types of seismic waves through it, S (shear) waves and P (compressional) waves. S waves do not travel through liquid, and P waves are dramatically slowed down by liquid. We observe both of these phenomena when sending these waves through the outer core which confirms it is liquid. However again, I do not think we will ever be able to send anything more tangible than a seismic wave down that deep into Earth because it will melt haha. So drilling deeper than a certain level is probably out of the question, but who knows maybe we will invent another way to 'travel' deeper into Earth in the future :) Very cool to think about, thanks for the question!
@@JoesFirewoodVideos it's the Kola Superdeep Borehole! here's a cool youtube video on it: th-cam.com/video/zz6v6OfoQvs/w-d-xo.html. It's ~12 km deep (~7.5 mi)!
Thanks for the input! That is a great idea, because I think I explain how granitic rocks form in little parts of different videos, but I don't think I have a video specifically for that, so I will work on that for a future video :D
@@GEOGIRL sure, Geo girl, I was actually studying about carbonatites from JD Winter and it was kind of overwhelming. Sometimes before studying a chapter I watch a video of yours to get an idea about the topic, that's why I was requesting for a video.
Yea, if you send me a message on Instagram or my email with the picture attached I can look at it, but there is only so much I can identify through pictures so no promises on a correct identification. You can find my email in the about page of my channel and my Instagram is @geogirl_gram. Thanks for the comment! -Rachel
@@GEOGIRL Thanks, today I plan to go back to the site in question, to take more pics and video. This is a fun hobby, for me, and exactness is not necessary. Thanks Roger Will e-mail a pic.
@@rogercotman1314 Hey I looked at the pics you emailed, very cool! I think it is a xenolith (basically clasts of previously deposited rock incorporated into intruding igneous rock formations), but I am not sure what the country rock is so I'd have to get a closer look to be sure. Thanks for sharing! :D
@@GEOGIRL Thank you, yes there are many examples of xenoliths in this general area. Are you on Facebook?? I have a post under Andrew Lane. A number of these igneous "somethings" seem to show an outer "egg shell" skin. Maybe, this outer skin is evidence of a cooling zone. Thanks again, for your response.
@@rogercotman1314 No, I am not on FB unfortunately, but yes, the outer eggshell things are altered rims. The outer rim of a xenolith is often altered due to its inclusion into the hot magma that picked it up and cooled around it. :)
Petrology is love - hated subject that I'm taking Couse on geology the love is can identify rock more details 😊 and the hated is doing lab things like point counting on thin section 🤧😭
It is wrojg to say that basaltic crust covers 75 per cent of the planet. It is rather 50 or 60 percent. Do not forget a lot of contnental crust in covered in water, e.g. the North Sea.

Yay! So glad you are enjoying my videos! What is your specialty in petrology? :)
Thank you for the video🙏
Very well explained video
Thank you so much for this. You are helping me prepare for my honors exam. Thank you so so much
Of course! So glad you found the video helpful :D Good luck with your exam! ;D
