Arctica or Arctida[1] was an ancient continent which formed approximately 2.565 billion years ago in the Neoarchean era. It was made of Archaean cratons, including the Siberian Craton, with its Anabar/Aldan shields in Siberia,[2] and the Slave, Wyoming, Superior, and North Atlantic cratons in North America.[3] Arctica was named by Rogers 1996 because the Arctic Ocean formed by the separation of the North American and Siberian cratons.[4] Russian geologists writing in English call the continent “Arctida” since it was given that name in 1987,[1] alternatively the Hyperborean craton,[5] in reference to the hyperboreans in Greek mythology.

“The minor supercontinent Arctica was one of the major pieces left after the breakup of Kenorland. About 2.5 billion years ago Arctica was comprised of the North Atlantic, Slave, Superior and Wyoming cratons of Laurentia plus the Angara craton of Siberia.”
