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 Plate Tectonics by C....  . This animation focuses of the plate tectonic development of our planet during the last 600 million years. Some highlights: 600 Ma - the start of multiple subduction zones along eastern Australia and Antarctica, the north-facing margin of Siberia (Mongolia & Amuria), and the Cadomian region of northern Gondwana 600 – 580 Ma - the conversion of slow-spreading ridges in the Kipchak Sea to subduction zones 580 Ma - the opening of the Iapetus Ocean 580 – 520 Ma - 1500 km of dextral strike-slip motion between Siberia and Laurentia 530 Ma - subduction of the Panthalassic midocean ridge beneath the Tasman-TransAntarctic subduction zone (SZ) 515 Ma - the conversion of the Central Iapetus midocean ridge (MOR) into a subduction zone and the start of the Taconic island arc 510 Ma - subduction of the SW Iapetus MOR beneath the NW Amazonian SZ; and the rifting of the pre-Cordillera terrrane from the southern margin of Laurentia 500 – 400 Ma - accetion and collision of island arcs in the Kipchak Sea to form core of Kazakhstania 495 Ma - the rifiting of Avalonia from Amazonia resulting in the opening of the Rheic Ocean 485 Ma - subduction of the ProtoTethyan MOR beneath the easternmost Kipchak island arc 475 Ma - rifting of the Cathaysian continents (N.China, S. China, Indochina, & Tarim) from the Indo-Australian margin of Gondwana 465 Ma - collision of the Taconic arc with the eastern margin of Laurentia 455 Ma - westward, Andean-style subduction begins along the eastern margin of Laurentia; eastward-dipping subduction begins along the western margin of Laurentia 445 Ma - Avalonia collides along the southern margin of Baltica and subduction begins along the southern margin of Avalonia 440 – 425Ma - 1500 km of sinistral strike-slip motion between Siberia and Laurentia 425 Ma - Baltica collides with Laurentia (Caledonian orogeny); Rheic MOR is subducted beneath Laurassia (Laurentia & Baltica); opening of Seventy Mile back-arc basin (BAB) along the western margin of LAurentia 420 Ma - subduction begins along northern margin of Gondwana 400 Ma - collision of southern Laurentia and northern South America (Acadian orogeny); Laurussia, reverses direction and head northward causing the conversion of MOR is the Seventy Mile Sea to convert to a subduction zone; Amuria begins to rotate counter-clockwise closing the Mongol-Okhotsk Seaway 370 Ma - initial collision between northern Gondwana (Amorican terranes) and Laurussia 360 Ma - collision of Seventy Mile island arc with western Laurussia (Antler /Caribou orogeny); Tarim collides with southern Kazakhstania (Tien Shan orogeny); northward dipping subduction begins beneath the Cathaysian continents (N.China, S. China, Indochina, & Tarim); South China (Yangtze craton) begins to rotate clock-wise closing the QinLing Ocean 360 – 300 Ma - 1000 km of dextral strike-slip collision between Armorican terranes of northern Gondwana and Hercynian Europe 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;
