Syntomapangaea is a supercontinent model I propose, it means "Soon all Earth". It is based off of Pangaea Proxima but with differences. The Eastern Atlantic becomes a separate plate and begins subducting under Europe and Africa East Africa becomes severed but eventually stalls and becomes a pseudo Madagascar in the Afroeurasian Plate Both sides of the Atlantic will develop subduction zones and island chains Antarctica is severed, West Antarctica becomes part of the South American Plate, East Antarctica eventually latches on to Afroeurasia's Indian Ocean subduction zone Syntomapangaea's forms around 0N/S 0E/W but eventually migrates to be a northern polar landmass
I believe that Amasia is probably the most likely future supercontinent mode. It follows the current trend of the subduction of the Pacific, which has been going on since Pangaea broke up, as well as recognizing it is unlikely for Africa to split in two, given that the East African Rift is the slowest-growing arm of the Afar Triple Junction, and is likely to die down and become an aulacogen. It also recognizes the African and Pacific Large Low-Shear Velocity Provinces as a barrier to both Antarctica and South America crossing the Pacific. It is also based on studies of the latitude of ancient supercontinents which conclude that they form roughly 90 degrees away from their predecessors. Novopangaea may not be possible, both because of the previous issues I pointed out with the presence of LLSVPs blocking convergent plate tectonics in the Pacific and the EAR's slow growth, but also because the Earth's mantle may be too cool for an extroversion cycle to begin. While Aurica and Pangaea Proxima both continue the Atlantic's Wilson Cycle, Aurica is an unlikely outcome as it is not likely the Baikal Rift will form a new ocean, and Scotese's Pangaea Proxima model relies on a faulty understanding of how subduction zones form; it assumes that they occur when oceanic crust becomes old and dense enough, while current evidence suggests they form around pre-existing zones of weakness like strike-slip faults or deactivated divergent plate boundaries.
Nice ! My favorite thesis is Novopangea , why obeys the east Africa rifting, obeys the Mediterranean Sea closure and obeys the Atlântic ocean expansion.
My favourite is Aurica because it follows the scenario of both the Atlantic and the Pacific closing and I find also find it really interesting that Eurasia splits.
I'm more a fan of novopangea, because extroversion is more likely than introversion. The 5th model (amasia but better) is even likelier due to othroversion, and it's better than the original because Antarctica must move SOMEWHERE.
There are problems with all three versions. Two of them , ignore the Great Rift Valley, in Africa. The middles, has issues with Madagascar not moving, and Antarctica staying still.
The Great Rift Valley is unlikely to break Africa in half because neighboring rifts are growing faster. Antarctica is barred from moving north by hot mantle plumes in the Pacific.
I mostly follow the Aurica hypothesis but with a few modifications. Based on the idea of the African Rift growing, both North and South. This would split Eurasia and Antarctica as well, forming a new Siberian Ocean. In addition, Nubia will merge with Eurasia enclosing the Black Sea and forming a Mediterranean Mountain range. Australia will dock with Eurasia around 100 million years from now when the Siberian Ocean first opens up. The new Australasia continent would begin moving farther south accelerating the closure of the Pacific while Chukotka attaches to Alaska, Similar to Scotese’s prediction, about 100-125 million years from now, the Atlantic will start to shrink with South and North America both approaching Nubia. Contrasting with Scotese the Australasian and Somalian continents will continue East to merge with the Americas on the West, South and North America will wrap around Western Nubia. Antarctica will be located on the southern edge of the landmass possibly scooped up by South America. This will likely be the last of the major landmasses to merge with the rest. Somalia will attach shortly after by about 300 million years from now, forming a modified version of Aurica. Now I just need to name it.
this looks like its modeled with gplates or a similar program. in gplates, you cant edit how the terrain looks until you go in and manually edit the year. when there are 200 years (in millions), its very hard to edit every one for realism, instead changing it every 50 million years or so
I think a combination of 1 and 2 is what I think is going to happen. I think east Africa is going to rift and the Atlantic is going to expand and then subduct.
La grieta del este de áfrica es poco probable que se divida el continente por le mitad, porque los grietas próximas están creciendo más rapido. Probablemente se dejará de creciendo en lugar de formar un nuevo océano.
Antartica will never leave its current position. Ever. however Eurasia will eventually bump into North America. North America will not move much. It's the only continent that remains glued to the mantel. It's stuck. The others are not
But now they'll have to add a detail to the most plausible scenario here: the recently discussed Indian subcontinental re-detachment. PS: Aurica IMO is least likely because there's almost no tangible proof of the Baikal rift valley going full split mode. Plus, the west Gondwanaland (Africa/SA) re-visitation thing--minus the African Rift Valley split, yet--just seems like lazy conjecture. If the Mediterranean is gonna close to varying degrees in all 4 (5) possibilities regardless, how does this happen? Also, kindly notice that the Scotese model is the only one that shows the Iberian peninsula breaking off with Africa's northward push...as well as the aforementioned lack of the African rifting. Amasia ignores this, too. Finally---and oddest of all--is Scotese being the only one to include the San Andreas/Cascade fault system activity. After all, it is most likely to happen since tectonic activity is easier to predict with a more recent timescale. Thanks.
Me gusta el modelo de pangea ultima porque Africa se puede unir con eurasia formando afre-eurasia y tambien australia se puede unir con la parte de Indonesia y Malasia Formando austro-afre-eurasia Y América del norte puede colisonar con rusia.
Amasia: Antarctica: Hello Stupidos im Stay in my current position Russia: Hello USA Stupido Usa: IS THIS PANGEA Russia: this is not pangea this is amasia Brazil:hello Fat Atlantic Ocean Australia: Hello USA I'm near u USA: hello Australia I'm near u too
Truth is these are all Theories here we May never know what Future of Continents out here will look alike we will be long dead when that happens out here.
The Australian plate moves around 62-70 mm (2.44-2.75 inches) per year in the direction of the north. It is predicted that the northern motion of the Australian plate will eventually make it bump against the Pacific Superplume, and change its course to collide with East and Southeast Asia. Some models predict it will go as far as Russia and Alaska.
2 and 5 seem to be the more likely scenarios considering they include both the understanding that the Pacific Ocean is closing up and Africa will eventually split into two.
Aurica is my favorite model because it breaks Eurasia into 2 parts and apparently makes Arabia, Iran, and Central Asia no longer have any connection with East Asia, South Asia, and the ASEAN. What I'm not sure now is what parts of Russia and Mongolia will be separated according to Aurica? What is the exact boundary of this separation? 1.Aurica 2. Your Amasia 3. Novopangea (separating East Africa and relocating it to India) 4. Pangea Proxima 5. Amasia
Epic proposals of the changes the planet will experience, shame the plate boundaries where not shown, we could really appreciate the movement easier, to see how the floating crust is added to or lost..Especially when some contients reverse track!
