The Earth was experiencing hotter and more volatile Archean tectonics, evidencing island arc volcanic activity and mountain building. The Trans-Hudson Orogen occurred when a number of Archean continental blocks came together, including the Superior Craton from the southeast and Hearne-Rae craton from the northwest. A microcontinent named the
