- This animation is an excerpt from Scotese and Elling (2017). The full-length version of this animation can be found at • 1.5 billion years of P... . This animation focuses of the plate tectonic development of our planet during the last 200 million years.
Some highlights:
200 Ma - eruption of Central Atlantic Magmatic Province (CAMP); PaleoTethyan MOR is subducted beneath Cimmeria; unknown sliver continent rifts away from northern margin of Gondwana; Mongol-Okhotsk seaway narrows; East Gondwana (Madagascar/India/Australia/Antarctica) begins to rift away from West Gondwana (South America/Africa)
190 Ma - the Karoo LIP erupts (Walvis Ridge / Tristan da Cunha hot spot)
180 Ma - Seafloor spreading starts in Central Atlantic and proto-Caribbean , rifting in Gulf of Mexico and the Western and Eastern Mediterranean; sinistral strike-slip between Mexico and North America; rifting begins in the Canada Basin between the North Slope block and Arctic North America; extension in the southern regions of the North Atlantic (between North America & Greenland, between Greenland - Rockall); subduction begins along eastern margin of Asia (Yenshanian orogeny)
175 Ma - spreading ridge in Slide Mountain BAB converts to subduction zone as North America is driven westwards;
170 Ma - Seafloor spreading between East and West Gondwana; seafloor spreading between Iberia and North America;
160 Ma - NeoTethyan MOR is subducted beneath Eurasia; Izanagi MOR connects with new MOR north of Exmouth plateau as
150 - Today - North America moves westward and the Rocky Mts are thrust skyward (Sierra Nevada, Sevier and Laramide orogenies)
145 Ma - Gulf of Mexico stops opening
140 Ma - Seafloor spreading begins in southern South Atlantic
135 Ma - Eruption of the Etendeka (Namibia)-Serra Gerral (SE Brazil) LIPs
120 Ma _ Rifting in east-central Africa (Chad / Sudan); complete closure of the Mongol-Okhotsk Seaway;
115 - 90 Ma - Creation of the Kerguelen plateau by voluminous reruptiosn at the Kerguelen hot spot (HS)
115 - 75Ma - Opening of the Olyutorska BAB of NE Siberia
100 Ma - Wrangellia collides with western North America (British Columbia); collision of Caribbean oceanfloor with Mid-America SZ results in “capture” of Caribbean and start of west-dipping SZ along the eastern margin of the Caribbean plate; Rifitiing in the Tasman Sea as Zealandia begins to separate from eastern Australia;
105 Ma - Seafloor spreading stops in the Somali Basin and between NW India and the Lut block;
95 - 50 Ma - Australia slowly rifts away from Antarctica
90 Ma - India rifts away from Madagascar opening the Madagascar basin
90 - Today - Sinistral strike-slip along the northern margin of South America as Caribbean plate moves eastward along transpressive boundary; creation of the Ninety East Ridge by the Kerguelen HS
80 Ma - Obduction of ophiolites in Guatemala and Honduras as Caribbean plate collides with Central America
85 - 70 Ma - The oceanic lithosphere of the Bering Sea is created at the Izanagi MOR
65 Ma - India, as it moves northward, collides with Lut block and carries it northward towards Eurasia; Eruption of the Deccan LIP;
60 Ma - Subduction of the Izanagi MOR beneath eastern Asia; Subduction of the NE Indian Ocean MOR north of Australia; Collision of the island arcs that makeup Kamchatka with NE Siberia; Capture of the Sea of Okhotsk;
60 Ma - Today - Collision of Adria/Apulia to form the Alps; 55 Ma - The Pacific plate changes direction (from N to W-NW);
50 Ma - India begins to collide with Asia; Greater Antilles arc (Cuba & Hispaniola) collides with Bahamas platform opening the Yucatan basin; Caribbean plate begins to move eastward with spreading at Cayman Ridge;
50 Ma - Today - The collision of India deforms south-central Asia and results in the southeastward “extrusion’ of SE Asia; Australia, together with India, rapidly rifts away from Antarctica
45 Ma - Extension begins in South China Sea
35 Ma - Extension begins in East Africa and Red Sea/Gulf of Aden;
30 Ma - Youngest ocean floor in South China Sea and Sea of Japan; closure of the dep marine connection between Tethys and the eastern Mediterranean;
30 Ma - Today - Extension begins in the Basin and Range; Collision of Arabia and Ian to form the Zagros Mts.;
25 Ma - Today - Baja California and California west of the San Andreas Fault are carried northwestwards with the Pacific plate; continuing extension in the Basin & Range
20 Ma - Seafloor spreading (oldest ocean floor) in the Gulf of Aden;
15 - 0 Ma - Calabria rifts away from Sardinia opening the Tyrrhenian Sea (due to slab roll-back); ~500 km of dextral motion along the North Anatolian Fault as Turkey is squeezed westwards between Arabia and Eurasia;
10 Ma - Today - The extension in the Aegean Sea; ~150 km sinistral displacement along the Dead Sea Fault ;
Really terrific. Thank you. I will use with my classes for years to come.
This is so cool. We have been using the animations by Dr. Scotese for years. We will continue to do so for years to come.
My 5 years son loves the music and this video. I don't know why he likes to watch such videos about continental drift
Oh, i thought it was a video about when the proxima pangea broke up..
This seems more right than the old one that curently is 5 years old now
