    You are doing such a good job at explaining everything and judging by how much work you put in each of your videos you must really like what you do. I am currently doing my major in geology and until i stumbled upon your channel i wasn't sure if i wanted to pursue a geologist career, but watching your videos is starting to change my mind. As you said in a previous video, its hard to find information on UA-cam about geoscience compared to the other sciences and you are doing an amazing job filling that gap. Please keep it up and never lose your sweetness. Thanks for everything. 😊

      Wow, this comment made my day! I am so happy that my videos can help convince you that geology is AWESOME! And a great path to pursue! ;D Thanks so much for commenting this, I hope my videos continue to be a source of both information and inspiration for you! ;)

    What an excellent video! Thermodynamics is always tricky to review let alone teach! Well executed! Im going to use this video as a review in the future. Your command of the various albeit disparate geology sub-disciplines continues to amaze!
    I’d have to say my favorite igneous texture is typical phaneritic texture. The typical texture of granite and granodiorites, rocks I’m currently working with! I like the juxtaposition of euhedral grains of plagioclase displaying oscillatory zonation against a fine-grained matrix. I’m vanilla, what can I say……..
    EDIT: actually rapakivi granites are gorgeous nevermind I’m not that vanilla after all…

    • @GEOGIRL
      @GEOGIRL  3 роки тому +4

      Haha! Anything but vanilla I'd say! Great choices! ;D
      And thanks so much for the kind words about the lecture, I am so glad you thought it was good, it always means so much coming from real geologists! :)))

    I absolutely love your passion. You explain everything in great detail and I'm understanding the information presented in class much better. Minerology was a bit rough, so I'm definitely trying to recap and continue to learn. Fortunately right now Petrology has been alright. But again, these videos have helped so much. Thanks you again!

    I'll go with pegmatitic, too. I once saw a large (5 foot) boulder in a park that was course grained like a normal granite or something (I'm no expert), but had these wonderful inches long orangish pink (orthoclase feldspar?) crystals embedded in it. So cool.

    It is interesting what gets a student to take interest in a subject. When you said thermodynamics, I got interested, because I recently heard that thermodynamics affects the direction of our perception of time.

    Hi Geo Girl,
    So what accounts for Spherulitic growth in Felsic Rhyolites?
    The literature says they ate 'common ' in glassy rhyolites, but what I observed is 'if you find them at all-they most likely will in igneous glassy rocks' which make them Ultra rare and not common at all.
    Add insult to injury and although these rocks are Felsic ( basic) they are dark colored as if they are Mafic??!?
    after initial nucleation around a we'll formed Crystal in the melt the sperulites grow outwards in chain connected mers ( polymers) and can be Crystals of Quartz and Crystals of Felspar Polymeric growths and I have heard of quartz/ tourmaline spherulites too.
    Microscopically the border materials are not glass or glassy and don't break like glass but are something fused together and mostly non fracturable.
    I'm totally perplexed!

    It's quite funny, in German "Struktur" refers to the small scale properties of igneous rocks, whereas "Textur" is the large scale characteristics (foliation, lineation etc.)

      Listening to English geology as a German is quite fun anyway. Too bad the Feldspat lost it's T in translation to feldspar. I wonder how then this strange word "feldspathoid" came into beeing.
