What do Shields Tell Us About Earth's History?--Phenomenon Explained

When you think of the terms "shield" and "geology", the first term you will think of is the Canadian Shield. But what is a shield anyway? And what do shield tell us about Earth's history? In this video, we'll look at shields, cratons, platforms, and the curious story of how rock formations tell us how the continents were formed and how Earth's surface billions of years ago was remarkably similar to today. Oh, and we'll find out who exactly came up with the term too.

    I just now found this video, and you, Loren. First time viewer, subscribed before the end of it! I have lived and worked most of my life all over the Canadian Shield and know it well: born in Sudbury Ontario, grew up around Parry Sound, worked out of Kenora for a while and dove back and forth more times then I can count. Stopping on Lake Superior to do some rock hunting is how I break up my trips. Thank you for all the info you shared I like learning something new about places I am familiar with. I can't wait to check out the rest of your videos

    That's the most impressive video on geology I've ever seen. The amount of information delivered is only overshadowed by the interest to learn more about these topics it evoked on me. Thanks a lot, definitely hope there's more of it.

    The Canadian shield is reason lake superior never gives up her dead. And why Wasaga beach exists on Georgian bay. The group of seven painted Canadian shield eons ago. Bobby Orr's uncle had a butcher shop on the shield as well. It has existed for quite some time now.

    If you ever want a chunk of the Canadian Shield, especially Superior Craton. Let me know. Especially if you want greenstone. I am part of the school of thought that doesn’t think plate tectonics was in operation in most of the Archean. The Archean of the Canadian Shield just doesn’t fit with the younger, even Paleoproterozoic rocks, where we see thing like passive margins, as in the case with the Huronian.

    Is the offer open to non- professionals because I'm from Michigan originally and I'm very interested in greenstone belts so would love to have a sample. I'm also quite interested in the Superior craton as well. I'm fascinated by the earlier developmental phases of our planet and the formation of the continental cores.

    @@stevenbaumann8692 Thank you so much! I've been fascinated with geology and geological processes since the age of 12 after reading Jules Verne's "Mysterious Island" and "Journey to the Centre of the Earth" (insert red face here lol). Fortunately, my dad was the type that when I was interested in a topic, he would get me all the books he could find. I also remember pedaling home from the library, my saddle baskets loaded down with geology texts.

    In our high school courses in geography India, we have mention of the Basaltic Traps[Denser] from volcanic fissures - spurting oozing lava spreading out much like the same-named Choco-Lava cake [analogy, if you will], However I had been wondering since a bit now as to how that would still not explain the Geographical feature of the Older [less Denser] Granitic[igneous] Deccan Plateau Highlands [the Peninsular Indian Highlands for the uninitiated]. Thanks a bunch for Clearing this out. I can now visualise these great Proto-continental Indian Shield [btw read something about the most ancient rock being discovered here recently] and the Spurting Oozing Basaltic Traps [and MUCH younger too ~66 mya vs the Pre-Cambrian Shields]. Cheers and God-Bless.

    Could you tell me a little bit about what editing software you use, the basics of how you create animations, and how you record your voiceovers? I'm interested in creating educational videos as a hobby, and I could learn a lot from your production process. Thanks

    I use Final Cut Pro (But started out on iMovie) and I record the animations with Motion (for complicated ones) or Keynote (For everything else). I know it's all on a Mac, but I find the tools very powerful for the price--especially Keynote as you can make freeform shapes and animate them. I write all my scripts and read them using a teleprompter attached to my camera, and just drop the images and animations over them.

    Very nice video. Unfortunately, the automatic subtitle generator is not working well and, for instance, renders "craton" as "creighton". Only Creighton I know is Creighton Abrams, the commander of Patton spearheads during WWII and, later, a quite high ranking general officer. He gave the Abrams tank its name. I found that funny. I've seen youtubers that put quick flashes of text to establish the spelling of words. However, that would be more than icing on the cake in this wonderful video.

    I thought I had put it in a diagram later, but the term is "Craton". Weird that it went with Creighton.

    Your thumbnail just screams "Captain Canada!". And yes the Shield is the core of North America along with the Wyoming and Slave Cratons. The rest to the south and west are just Johnny come lately's crashing the party.
