- 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 300 million years.
Some highlights:
300 Ma - closure of Central Asian Oceans (Altaids) and accretion of Kazakhstania between Europe and Siberia (Urals); subduction of PaleoTethyan MOR beneath Kazakhstania and Cathaysia; rifiting of the Cimmerian continent ( Sanandaj-Sirjan terrane of Iran, Sistan and Farah blocks of Afghanistan, Lhasa, QiangTang, and Sibumasu (Siam, Burma, Malaysia, and Sumatra) from the Indo-Australian margin of Gondwana; collisionof LAurusssia and Gondwana to form western half of Pangea (Alleghenian/Variscan orogenies); accretion of Chileana and Patagonian terranes of SW Gondwana (Cape orogeny)
260 Ma - collapse of Seventy Mile back arc basin and collision of Sonoma island arc along western North America; accretion of Marie Byrdland and Zealandia to East Antarctica and eastern Australia; Eruption of the Omeishan LIP in SW China;
255 Ma - closure of Solonker Sea between Amurian and North China
250 Ma - eruption of the West Siberia large igneous province (LIP)
245 Ma - opening of Cache Creek BAB as Wrangellia rifts away from northwestern South America; opening of Slide Mountain BAB as Stikinia rifts away from northern Mexico
240 Ma - Sibumasu collides with Indochina along Bangong-Nujiang Co collision zone
240 - 220- Ma - subduction begins along southern margin of Cimmeria (propogating east to west)
220 Ma - closure of QinLing Seaway and accretion of Songpan-Ganze as South China (Yangtze craton) collides with North China; initial rifiting in Central Atlantic region (Newark group)
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)
195 Ma - Final closure of Paleotethys as Cimmeria accretes to Eurasia; BAB between QiangTang and Lhasa opens;
190 Ma - the Karoo LIP erupts (Walvis Ridge / Tristan da Cunha hot spot)
185 Ma - the Pacific plate is created at the Izanagi/Phoenix/Farallon triple junction
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)
180 - 100Ma - Wrangellia moves ~3000 km northward closing Cache Creek BAB
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;
165 Ma - Caribbean (B’’) oceanic crust is created near Izanagi/Phoenix/Farallon triple junction
160 Ma - NeoTethyan MOR is subducted beneath Eurasia; Izanagi MOR connects with new MOR north of Exmouth plateau as
150 Ma - Rifting in South Atlantic; Stikine terranes collide with North America closing the Slide Mountain BAB; Lhasa-Qiangtang BAB closes
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;
120 -90Ma - Eruption of large LIPs in the SW Pacific (Manihiki, Ontong-Java)
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
110 Ma - Seafloor spreading begins in the northern South Atlantic; the Philippines island arc rifts away from the margin of S. China;
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;
100 - 50 Ma - Dextral strike-slip along western North America carries Wrangellia and portions of the Stikine terranes, northward (~1500 km).
what about land inside the water when plate tectonics . one animation video please.
