New research reveals Tasmania was once far away from Australia
New geological research at the University of Tasmania has revealed that Tasmania could once have been miles away from Australia.
The new paper published in international journal Geology shows evidence that North America and Antarctica were once linked, with the land that is now Tasmania sandwiched in between.
These findings build on earlier research by Dr. Jacqueline Halpin, from the ARC Centre of Excellence in Ore Deposits (CODES) at the University of Tasmania, which supported a link between sedimentary rocks found in the northwest of the state and those found in Montana, Idaho and southern British Columbia. That means that Tasmania and North America were geographically very close when they formed part of the Nuna supercontinent, 1.4 billion years ago.
PhD student Jacob Mulder who helped put together the research paper explained: "While this new research corroborates the link between Tasmania and North America, it goes further by providing strong evidence that Antarctica was also part of that chain, with Tasmania relatively closely squeezed in between, importantly, it also indicates that Tasmania was situated a substantial distance away from the land masses that later formed modern day Australia."
