Evidence of Australia separated from North America found

Researchers of Curtin University  (http://www.curtin.edu.au/) have discovered rocks in northern Queensland that bear striking similarities to those found in North America. Australia was actually part of North America 1.7 billion years ago. The rocks found in Georgetown, 412 kilometres west of Cairns, have signatures that are unknown in Australia and instead have a surprising resemblance to rocks found in Canada today.

The team was able to determine this by using both new sedimentological field data and new and existing geochronological data from both Georgetown and Mount Isa.
