South China (continent) South China (continent) South China, also known as South China Craton, South Chinese Craton, or Yangtze Craton, was an ancient continent (craton) that contained today's South and Southeast China, Indochina, and parts of Southeast Asia (i.e. Borneo and adjacent islands). 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
Pangean megamonsoon solar insolation shifted toward the Southern Hemisphere. Air then traveled from Laurasia (region of high pressure), across the Tethys Ocean to Gondwana (region of low pressure). Moisture advection toward the Southern Hemisphere would have fueled heavy precipitation along the Gondwana coasts, while Laurasia remained very dry. There are marked similarities between factors contributing to the East Asian monsoon and those that would have influenced Pangean climate. This not only supports the theory that Pangean climate was dominated by the monsoon, but also aids in the study of it, providing paleoclimatologists with a present-day example to which they can compare their
