South China had been part of past supercontinents, including Rodinia, Pannotia, Gondwana, Pangaea and Laurasia. About one billion years ago, during the late Proterozoic, the Rodinia supercontinent formed. South China was part of Rodinia. South China was bordered by the Mirovia Ocean to the north, Siberia to the east, Australia to the west, and Laurentia to the south. 750 million
Pangaea that took place between North America and Africa produced multiple failed rifts. One rift resulted in a new ocean, the North Atlantic Ocean. The Atlantic Ocean did not open uniformly; rifting began in the north-central Atlantic. The South Atlantic did not open until the Cretaceous when Laurasia started to rotate clockwise and moved northward with North America to the north, and Eurasia to the south. The clockwise motion of Laurasia led much later to the closing of the Tethys Ocean and the widening of the "Sinus Borealis", which later became the Arctic Ocean. Meanwhile, on the other side of Africa
