The ins & outs of a proterozoic supercontinent - what is the significance of 990-900 Ma orogenesis for the assembly of Rodinia?
Grant number: DP0343406
The hypothesis that all of Earth's continents came together one billion years ago to form a supercontinent known as Rodinia has invigorated debate about ancient continental distributions. Current models depict a flawed configuration for Rodinia, since they assume that continental fragments preserving evidence for quite different episodes of tectonic activity between 1350 and 900 million years ago developed at the same time. This project will make new correlations based upon careful observation and precise isotopic dating of rocks in Antarctica and Mexico, and will use these data to develop a more realistic picture of the ancient Earth.
