Rift! Geologic Clues to What’s Tearing Africa Apart

[@charlesmiddleton3247]

My love of geology, rocks, minerals and nature go back to my childhood days when being poor. I had to find something to do so anything nature, I gravitated to. Rocks were so fascinating to me. I could sit for hours and study their composition, shapes and textures even though I didn't know much of anything at that age. This is so fascinating and so informative and I thank you for its content.

3:33 The chain of volcanoes that runs along the roughly 6,000 kilometer (3,730 mile) long East African Rift System offers further testimony to the breaking apart of the continent. In some areas around the outer edges of the Rift System, the Earth's crust has already cracked open, making room for the magma below. From the Red Sea to Mozambique in the south, dozens of volcanoes have formed, the best known being Mt. Kilimanjaro and Mt. Nyiragongo.

Fascinating lecture. I'd never considered the drifting super-plume before. Would it be reasonable to draw a comparison in terms of fluid-dynamics, between the Coriolis effect in the atmosphere causing localised high-pressure areas to rise away from the gravitational centre of the earth? The lithosphere is a lot denser/more viscous fluid than the atmosphere, so the plumes would be slower on real time. As we have 'surface weather', then there may also be an equivalent sub-surface weather between the core and the crust, only on a geological timescale. (if you get my drift)

One of the questions regarded will Africa completely split apart. One of these rift systems was discovered underneath North America. The Great lakes are our evidence. The rifting was incomplete and stopped. Perhaps this might happen in Africa as well. Another area of spreading that was stopped is in Nevada. Just because there is rifting now does not mean that there will be rifting later.

[@alexburke1899]

Great Lakes were formed by glaciers. The New Madrid fault caused by Reelfoot Rift under the continent (where the North American split failed) has nothing to do with the Great Lakes. Weight and glaciers carving out the lobes produced the Great Lakes. I don’t think they filled completely until 3000 years ago which is basically yesterday.

[@cannondale1950]

@@alexburke1899 You are partially right, Alex, but there is convincing evidence for an incomplete rift known as the Mid-Continent rift nearly 1 billion years ago that curved through the current Great Lakes and then headed south through Minnesota, Iowa and part of Kansas.

24:48 Why is the thorium and uranium concentrated in the crust? They're among the heaviest elements, so shouldn't they sink down into the core?

It is said that those elements don't end up in minerals until late, in what's left i.e. in pegmatites. I.e. in the crust.

[@tobuslieven]

​@@jonashellsborn7648 Thanks for the helpful reply. I'm not sure I understand the process. Is the following roughly correct? So they don't sink because they're in solution when the Earth was liquid? But then they crystallise out in the crust as that's where the temperature drops enough for them to come out of solution and combine into a solid mineral?

[@barbarawarner1442]

Dear tobuslieven. I wondered how that can be. Guess it is from all that shifting and up and down thrusting and vulcanism, dynamic system...

[@davidskorupa4827]

It could have sunk to the middle and only traces are left in the crust. We could be spinning around a nuclear bomb, the earth core could be a ball of solid plutonium like the fat man bomb dropped on Nagasaki in 1945. Now that could be the next movie with Bruce Willis.

The last leg of the Hawaiian chain is parallel to the previous equator. The Hudson comet tilted the crust, not the core.

[@johnnash5118]

I suspect that the theoretical "Super-Plume" is actually the same mantle upwelling that continued on after the oceanic plate spreading ridges subducted under the African Plate. This vast mantle upwelling mechanism, with its origin well below subduction, with commonality worldwide, fits the rift evidence better than the theoretical "Super-Plume." You can project mantle upwelling phenomena onto other regions such as Baja California and the American Basin & Range Province; they're all divergent, and are associated with subducted spreading ridges. Indeed, Baja is proof that mantle upwelling continues after its spreading ridge subducts, rifting the over-riding plate, and forming a new spreading ridge.

[@xtevetyler5332]

@21:16 you state the noble gases, the inert group 8 elements do not react with other elements, that is not strictly true, We studied a particularly strange compound at university that of Xenon trioxide (Xenon in an ozone pyramid XeO3 being a particularly unstable compound of xenon in a plus 6 oxidation state. It behaves as a very powerful oxidizing agent, and liberates oxygen from water slowly, but accelerated with exposure to light. predominately a dangerously explosive reaction with most organic materials. When it detonates, it releases xenon and oxygen gas. which isn't surprising as it is Xenon and Oxygen (or more correctly Ozone) . However I am not being quarrelsome deliberately, and it is somewhat irrelevant to the impact of the article you are presenting, I just thought it was an interesting side distraction, and largey you are correct as these elements have completed outer orbitals so require no other element to satisfy the quantum desire of filling the outermost shell (or react with another element, not even themselves! we are used to say Oxygen the element forming the Oxygen molecule by pairing up as O2, even tripling up as O3, and not being seen naked as just O, we do see Ne in isolated molecule arrangements, so... It is very correct to state that noble gases esp Helium and Neon are non reactive but xenon and krypton will react with fluorine or oxygen to form XeF2, XeF4, XeOF4, KrF2 etc Other than that I really am enjoying the documentary/lecture thank you sir.

How do you know what the ratio of primordial isotopes was?

[@maureenllinares8276]

Geochemists usually use chondrites as a reference. Chondrites are meteorites that are not differentiated, which means they are a clue to the initial abundance of different isotopes. In fact, they just look for something that stayed in an initial stage to compare with. The earth is now differentiated, which means heavy atoms will go to the center of the earth, volatile will go the other way. And we can also predict this migration with the electronic and nucleus configuration of atoms. To this initial stage, you need to add the contribution of radioactivity. Hope my explanation was clear...

[@MaryAnnNytowl]

My opinion on the matter is that it really depends on how slowly the process of rifting moves. If slowly enough, there should be no issue with any huge spillage of magma. After all, there's no signs of any of that happening at the other rifting places around the world, like where Europe and North America rifted apart, or where South America and Africa rifted apart, either. It would only happen if the rifting becomes dramatically fast, ripping the continent apart violently and quickly rather than more slowly and relatively gently (for what it is) that it's opening up right now.

Interesting for sure. Clear presentation. I wonder how we get a carbon type vulcano so close, or inside of this super plume?

[@slehar]

Great great lecture, but technical nit-pick at 7:14 this whole figure is WRONG! It is NOT the pressure of the rising athenosphere that pushes the plates apart. If THAT were the case, then the rift valley would BULGE UP! Not sag down! No - what is happening is the WHOLE convection cycle - the plates are "sucked down" into the oceanic trenches AS MUCH as they are "pushed apart" at rising zones, but in truth, the REAL traction of the mantle is along the WHOLE LENGTH of the continent which drags the continent in opposite directions from the rising plume, and that plume does NOT push its way upward, but rather, it is dragged upward by the VOID created by the diverging crust pieces. The rift valley sinks because the continent is dragged away from that spot, so it falls into the void, even as it is re-filled from below. Am I not right? (Amateur geologist here, this point has always bugged me. Tell me if I am wrong)

[@MrSinister718]

You're wrong. Don't quit your day job. Leave Geology to the pros.

[@barbarawarner1442]

Slehar, yes. I'm just asking curious. Fellow amateur here, I theorize that both pushing and separation are operating here.

[@slehar]

@@barbarawarner1442 Yes there is some pushing, e.g. the bulging rise of the mid-atlantic ridge suggests a pressure buildup there. But the mantle convection is a whole complete cycle, rising here and sinking there. But the continents are "stuck" to the mantle that they ride, when it moves, they are dragged along with it. That creates a void at the spot they just vacated, and the void allows hot magma to rise to fill it, and perhaps to over-fill it. But its no good "pushing" on the continent from behind, thats like trying to push a carpet, it just wrinkles up under compression. It is the horizontal part of the convection loop that drags continents around.

One point was missed in helping us understand your research. In your talk on the noble gases of helium and neon being used as research tools to understand the Earth you do not mention why these two gases are so valuable as measurement tools. The reason is relatively simple and would have been beneficial to explain to us. You talk about how materials can degrade and produce a Helium-3 particle. You do not mention that the Helium-3 and Helium-4 particles remain stable for very long periods of time and don't degrade. Since they don't degrade very much they are stable benchmarks or rulers we can use to measure.

[@Dragrath1]

@@russlehman2070 Looking at the map of plate boundaries and given how the geology of the west coast has varied over the last 40 or so million years it seems a bit different in that the rifting in the gulf of California is really the continued activity of the East Pacific Rise which North America has been passing over. Formerly there was a massive Plate moving East from the East Pacific Rise that formed the center of the once vast Pacific Ocean(i.e. the East Pacific Rise was formerly the ridge at the center of the Pacific Ocean) Today the other half the former Farallon plate is almost gone since both North and South America have been moving west leading to the Farallon plate subducting. Nowadays the North American Plate has passed over the East Pacific Rise so only small remnants remain of the former eastward moving plate in the North with the Juan de Fuca plate forming the cascades and to the south the Rivera Plate and Cocos Plates respectively as well as the Nazca plate that is the part subducting under south America. Along the California coast where North America has passed over the East Pacific Rise Subduction ceases as the Pacific Plate is moving west as well, but since their Parallel velocities are different they are sliding by each other like two cars on a highway resulting in the Transverse motion. Remnants of the former subduction of the Farallon plate can be seen in the form of the Sierra Nevada mountains which once formed a continuous subduction Arc analogous to the Andes in South America. Eventually when the last remnants of the Farallon plate subductaway as North America finishes passing over the East Pacific Rise the San Andreas will become fully continuous from Central America up towards Alaska with composite cone volcanism no longer occurring in North America. What is occurring in the Gulf of California is really that transition as the East Pacific Rise is being overtaken by North America so basically regular old Mantle convection not a super plume Though there is a Plume in NA creating the Yellowstone Hotspot it isn't rifting North America. And there does also seem evidence suggesting there to be some sort of rising Plume Below New England based on seismic data but the nature and details of that situation are too murky at present to discuss with any clarity.

Caver461 Possibly due to the fact that the earth's crust is much thinner in the deepest parts of the ocean. This rift widens and fills with earth. Also all volcanoes are not explosive. Some explode and some consistently ooze.

+Caver461 Molten rocks are not all along the line. There are some isolated spots. The geologist are more lost than the Malaysian airplane. Why the plume don't push up the crust forming a dome instead of a valley. Really don't make sense.

[@Arthion]

+Francisco Madrigal The rifting is being caused by the pressure from below, that same pressure that is uplifting the ground into domes. It's kind of like blowing up a balloon, at some point the pressure becomes too much and it bursts, in the same way the pressure is causing the uplifted ground to fracture. Also the reason why the uplift and volcanism is highly concentrated in different areas would most likely be due to a combination of differing thickness in areas of the crust and differing pressure from the plume below along the trail of the rift.

[@TWOCOWS1]

actually, the "Kenya Dome" is not a dome at all, but a raft of super ancient craton--to hard for the rift to cut through it, so it has gone around it.

will never see that on US news tho, too into indoctrinating Americans to show actual news. hope the people in Kenya are staying safe from the Rifts.

California today July 4 still going 2019 just had a earthquake in the united states.

[@johnackerman4546]

The East African rift is not due to the asthenosphere intruding the lithosphere. In prehistoric times (4000 to 687 BC), a planet 0.2 times the mass of the earth repeatedly became captured in a geostationary orbit 36,000 km above Mt. Kailas in the Himalayas (by tidal drag). It's tidal effect drew all surrounding lithospheric plates toward it creating the Red Sea rift, the Apennines, rotated the Arabian plate NE, the northern Alps, the Indian sub-continent, Malaysia, Australia, the Japan and Philippines and raised the Hindu Kush etc. Due to the momentum of those recent encounters these plates are still moving. (see Miracle: The Creation of the Earth)

Which part of the fiction section of my local library do I find your book?

[@kananaskiscountry8191]

how many pieces does Africa split into???

[@MrSinister718]

4 - South Africa, the Congo, Middle Earth, and Wakanda.

Meanwhile north of you at the Large CERN Hadron Collider, a 7 month construction repair job continues. Collider damage was caused by a controversial particle test that exceeded equipment capacity and has left humanity wondering if the earthquake rumors are true. Perhaps this team of geologists and vulcanologists will start a useful correlation study of Earthquakes vs. CERN Collider shots. The science emerging out of CERN seems to indicate that particle collider shots in 1-trillion electron volts range and up, are causing simultaneous earthquakes along super-concentrated magnetic field lines on a global scale ... occurring hundreds and thousands of miles away. There may be a greater mission in store for this team ... if they dare to study and report on it publicly.

Please come to Taos, New Mexico and study the Rift here. The Rio Grande Gorge is what its called. Its not a gorge its a rift.

[@razorransom1795]

Hmm.... That makes sense, then in a way the Rio Grande river is totally on a fault. Most giant rivers seem to form over top of faults, being the lowest elevation and easiest path to travel. Those faults, at least us ones, are probably cracks in the crust from one of the major asteroid impacts. That makes me wonder about the Colorado River, and I know the Allegheny is on top of a major ancient one.

[@peterquintana3307]

Thats interesting that's what I told my girlfriend when we visited the bridge at taos. The sides of the gorge fit like a glove. This was back in 04 we got married shortly after. We live in Colorado, but I also like the New Mexico landscape absolutely beautiful.

Africa is splitting apart!

[@claudelebel49]

I thought the answer to what was tearing Africa apart was plate tectonics.

[@johnhedges5619]

Send in robots when research is too dangerous for human discovery. Plant your instruments when it's safe. Good explanations. Thank you

[@warpdriveby]

Are carbonitic volcanoes essentially erupting what might become marble under other conditions or is the origin of the C in the mantle/boundary?

[@theklshow4691]

hey everybody

[@rd8370]

Hey

[@andrenewcomb3708]

Is the English Channel a rift? In petroleum recovery they are able to mine laterally . . . could that be used to relieve pressure? Not all of Africa is at risk here?

[@aliha8313]

hi , tank you .

[@aliha8313]

very good video

[@kiptooj]

There you go. Best athletes originate from the Kenyan Dome and Ethiopian Dome of the Rift complex.

[@jamesyoungblood555]

A very good explanation of what's happening in and on this planet we live in. Thank you so very much. Shalom

[@davydacounsellor]

From the title " it's the USA that's tearing Africa apart.

Fascinating lecture! ☝🤓

The table lands in newfoundland i believe are mantle plume peridotite to look it up they call it weathered peridotite which is wrong

[@kimmerdkd]

More and more is being revealed at breakneck speed with regard to previously held ideas in what we perceived to be solid reality. Remarkeably not everything happens imperceptibly over millenia, rather, in some instances events thought to have taken millions of years may have taken place in a matter of hours... thats pretty scary!

[@LDiop-ig9zs]

Could it be that Africa is spreading and getting larger and not splitting into.

[@paulcollins9397]

Ignore Taklamakan! (It skipped out of its crater & ended the Younger Dryas.)

Interesting, Buddy drops the g from his words. Has other Welsh word pronunciations of English.
