    Holly crap dude that was awesome. You gave it to us with both barrels blazing, "Yeh". Really great scope, great regional tie in. Great brief explanation of the unconformities, monoclines, anticlines. We use to say, it's like trying to stuff 100 pounds of _ _ _ _ in a 50 pound bag, but you did it. My hair hurts. Thanks so much for sharing with us all, out here in amateur land. We love geology too, we're just to burnt out to remember all the stuff the pros remember. We are so grateful for the help. It is frankly a frustrating mystery why millions more people don't fall in love with geology. I use to work for a civil engineering lab years ago, going to quarries to do sampling in Colorado, and that's when I caught the bug, with the first piece of petrified wood I pulled out of the quarry wall with my own two hands. It was thrilling, and I've been maniacally trying to piece it all together for the last 35 years. Lectures like this help out so much to give us a big picture story. Please do more.

    I live in the Pacific Northwest. I’m not a Geologist but do enjoy learning about geological formations. Because of watching your video about US east coast geology formations, I learned more about US west coast geology formations in my backyard. Congratulations on a well produced and educational presentation on Virginia geology. It served for this observer to contrast the differences and similarities between US east coast and US west coast geological formations.

    Your slide showing Stratigraphy of the Valley and Ridge Province illustrates the Mauch Chunk, Pottsville, and Conemaugh as part of the Acadian Orogeny. The Mauch Chunk, Pottsville, and Conemaugh stratigraphic units form part of the Alleghanian clastic wedge, deposited by the Alleghanian Orogeny. In West Virginia at Spruce Knob, the Price Sandstone (upper part of Pocono) is overlain by the Greenbrier Limestone (passive margin unit) , which is overlain by the Mauch Chunk and Pottsville (Alleghanian clastic wedge stratigraphic units).

    Yes, this video is quite old but I only found it today and because of Iapetus and Atlantic I am now wondering how is it that first the oceanic plates subduct and then later a mid-ocean ridge appears in the same place?
    I've heard that plate tectonics is created by convection of the earth's mantle. So I imagine that something rises in one place in the coat and therefore has to go down in another place, which breaks the coat into a kind of bubble? The panels float on the mantle and are either pushed apart or towards each other. Do the places where the material moves up and down also move?

    I can't get enough of visualizations of Geology; esp video, but diagrams must suffice. In the next few years more and more CGI will be applied to Geology; and I can't wait. It's already been done for Astronomy; as everyone (with an interest in science) remembers their first time in a class trip to planetarium watching Theia hypothesis; the theorized protoplanet that collides with Earth to form the moon. We need more CGI artists to get into Geology, damnit!

  • @nibiruresearch
    @nibiruresearch Před 2 lety

    I know of a missing link in the education of geologists. They tell us that our planet Earth has the most to fear from an asteroid impact or volcano eruptions. But when we look at the many horizontal layers that we find everywhere on our planet, we clearly see the effect of a repeating cataclysm. These disasters are mentioned in ancient books like the Mahabharata from India and the Popol Vuh from the Mayans and others. They tell us about a cycle of seven disasters that separate the eras from the world. Certainly, regularly recurring global disasters cannot be caused by asteroid impacts or volcanic eruptions. The only possible cause is another celestial body, a planet, orbiting our sun in an eccentric orbit. Then it is close to the sun for a short period and after the crossing at a very high speed it disappears into the universe for a long time. Planet 9 exists, but it seems invisible. These disasters cause a huge tidal wave of seawater that washes over land "above the highest mountains." At the end it covers the earth with a layer of wet mud, a mixture of sand, clay, lime, fossils of marine and terrestrial animals and small and larger meteorites. Forests that existed are flattened and because of the pressure from the layers on top the wood is changed into coal. These disasters also create a cycle of civilizations. To learn much more about the recurring flood cycle, the re-creation of civilizations and its chronology and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9
