Volcanoes 2, Edifices and Hazards
We go through 2 lists. The first documents types of volcanoes. The second explores major volcanic hazards.
มุมมอง: 172
วีดีโอ
Volcanoes 1, Eruption Styles
มุมมอง 2012 หลายเดือนก่อน
Bubble behaviors control effusive and explosive eruptions.
Magmas 3, Magma bodies and how they change
มุมมอง 1462 หลายเดือนก่อน
Topic today defines plutons, dikes, and sills. We then go through a short list on how magma changes composition by mixing, assimilation, or fractional crystallization.
Magmas 2, Magmagenesis
มุมมอง 1402 หลายเดือนก่อน
Magmas can be produced only if the geothermal crosses the solidus. We explore -P, T, and H2O mechanisms for making magmas.
Magmas 1, Textures and Compositions
มุมมอง 1632 หลายเดือนก่อน
Start igneous petrology with intrusive and extrusive igneous textures. That is combined with magma composition to create a table of rock names.
Earthquakes 4, Hazards and their prevention
มุมมอง 1612 หลายเดือนก่อน
We go through a list of earthquake hazards mechanisms. We also talk about how to prevent those specific hazards.
Earthquakes 3, Measuring Earthquakes
มุมมอง 1042 หลายเดือนก่อน
Discuss the seismograph and how it can be used for triangulation and establishing earthquake magnitude.
Earthquakes 1, Stress and Anatomy
มุมมอง 1212 หลายเดือนก่อน
Faults are produced by brittle failure of the lithosphere in response to stress. We sketch a fault and define focus, epicenter, scarp, etc.
Earthquakes 2, Types of Faults
มุมมอง 2332 หลายเดือนก่อน
Normal Faults, Reverse Faults, and Strike Slip Faults are introduced.
Plate Tectonics 2, Evidence for Tectonics
มุมมอง 4073 หลายเดือนก่อน
We explore compelling observations that support the Theory of Plate Tectonics.
Plate Tectonics 1, Types of Boundaries
มุมมอง 2.8K3 หลายเดือนก่อน
Divergent, Convergent, and Transform Plate Tectonic boundaries are described.
Earth Interior Structure 2, Layers by Behavior
มุมมอง 2263 หลายเดือนก่อน
Five structural layers of Earth's interior. Lithosphere, asthenosphere, lower mantle, outer core, and inner core.
Earth Interior Structure 1, Layers by Composition
มุมมอง 1553 หลายเดือนก่อน
Crust, Mantle, and Core described by their chemical composition.
Mineralogy 3, Mineral families
มุมมอง 2113 หลายเดือนก่อน
Introduction to silicates, carbonates, and oxides. Then a few minutes on Diamonds.
Mineralogy 2, Physical Properties
มุมมอง 1133 หลายเดือนก่อน
We go through a list of ~7 different optical and physical properties that can be used together to successfully identify minerals.
Mineralogy 1, Definition and Formation
มุมมอง 1643 หลายเดือนก่อน
Mineralogy 1, Definition and Formation
Geochronology 1, Dating and the isotope

Geochronology 1, Dating and the isotope
Weathering and Erosion 3, Mass Wasting

Groundwater 2, Geography and Problems
I run bauxite as one of the ingredients I work with. I use a Cat 950M loader to work the bauxite. I need a 3mm minus size to use. Occasionally I get chunks that are softball size and larger. So… I backdrag the material with the loader bucket against the concrete floor. It sometimes takes the full weight of the loader to break a chunk of bauxite. The chunks are sometimes very beautiful inside. Part of my soul hates breaking suck a beautiful material up but it has to be done. This material will also flow like water when it’s pulverized into a powder. I’ve had 2000 pound large bags of bauxite that have been sitting upright for weeks… sometimes randomly fall over at the slightest touch because it flows so easily. I touched a bag of it very lightly one day and the bag flipped over so quickly that I didn’t have time to react. It fell onto my leg and pinned me until I could use a bar to pry the bag up enough to get out from under it. Bauxite is a very cool material tho. I love it.
if you have the time, could you make a video about the different types of glaciers?
Sir you saved me. Thanks a looooooooooooooooooot
Sir I really appreciate your videos. I'm a geology student and you videos help clear a lot of things that the text book really confused me on.
thanks man your video helped me a lot
Which type of volcanic activity is related to formation of clay layers of multicolour.& Which rocks form clay layers for kilometers .
Thanks from France 😁
Nice lectures keep it up
Keep going
In what software you explain us the the course ? Cuz I want to have a resumé to my exams like tthat aswell 😅
MashaAllah beautiful, Good nice ❤🙏💎
Wrong formula Its Ca2 (Mg, Fe, Al)5 (Al, Si)8 O22, (OH)2
لدي كثير من الأحجار النيزك والأحجار الألماس سية الخام وأريد أن أبيعهم لدينا في دول العربية لا يعرفون قيمتهم أريد أن يتواصل معي يفهم بهم وأريد أن
Was just thinking about mass wasting in Picos de Europa...
For Darcy's law, if the pipe narrows at one of the ends, how do you get the area (A) for the equation if it's not constant? Do you just calculate the average of both ends?
I'm not sure. Good question. Maybe a hydrologist can answer... or the internet.
Nice lecture, how can I get physical copy of your notes sir
I love the details you give.. Seems like you love what you’re doing and I love that
Thanks Hobo!
Man, I needed you back in the day when I was taking Mineralogy and Petrology courses. A great presentation!
The Best class on Feldspar which I have seen over TH-cam... Thank you very much sir
You are most welcome
Thanks
You can not use silicates in dentistry at all. They are toxic.
Wish I had these when I took my Climate Change course!
Hello, where i can find the mineral science 23rd book for free on the internet ?
I cannot help with that.
Hello,can you put the link of the pdf of the book mineral science ?
there is a free Mineral text at opengeology.org
Very cool!💿🏝️🏠🏰🗽
Can you put the pdf of the book ?
I cannot. But there is a free Mineral text at opengeology.org
Hiii،do we can use magnetic stone as ring؟
Thank you. This cleared up so much disinformation on TH-cam
Just watched serpentinisation... Now on to the next 👍

So clear Kenneth. Thanks
How do we all know what adamantium luster looks like, but we've never seen adamantium because we are not x men.
adamantine means 'like diamond'. The marvel verse sometimes get in the way of our marvelous reality
My favourate gemstone . So many different variations
It is a great one. Not many people favorite it. But its optical qualities are special.
@kennethbefus sphalerite is my favorite because I am an expert at locating and extracting very nice specimens that can actually be faceted. It is most abundant gemstone near me. Cleophane is my favorite variation of sphalerite. Mostly found in Bulgaria.
Ceux qui sont là à cause d'Elsa (Merci Virgile)
Trop réel mon gars j'ai adoré le passage à 20:20 il a dead ça
tu dis les termes toi mon sauce gars
JE HURRLLEEEEEEEE MANN VIVE BABYLONE
OH TANENBAUM OH TANENBAUM, oui c'est vive le vent en allemand
t'aurais pas 6 balle à me prêter en vif ? j'ai une galère la c'est tarpain chaud mon fraté de la cannebière
You said Dear , Beryl if transparent , is of high value , but if opaque then no value ? I got Beryl stones in about 8 to 10 inch length , about 3 inches thick
How many types of External symmetry are there ?
Nicely explained ❤
thank you
Amazonite
Epdote

Do you have any videos that describe how massive non terminal alpha quartz forms? I'm interested in this specifically but im finding a lot about macro crystal formation (because thats what people find special about alpha quartz, understandably).
No free space to grow euhedral terminations. Or growth fully fills space.
J'en ai un noir avec des graines vertes à l'intérieur, comme du verre. Où puis-je le vendre ?
Excellent lecture, much appreciated!
life saver
I have corrandum but its cover with i think graphite. . Do u know how to remove graphite and heat corrandum to light its colour
for cyclosilicates how are they SiO4 around a cyclo if the formula is Si6O18
I have Red cinnabar if any want reply me. Thank you
i need cinnabar original brother you have
Thank you so much Great vid
Great video. For the second example, what happens in a case where the mineral isn’t given by the professor?
that is the real life scenario. Have to use geologic intuition
