The ins and outs of a Proterozoic supercontinent - what is the significance of 990-900 Ma orogenesis for the assembly of Rodinia? 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 ....The ins and outs of a Proterozoic supercontinent - what is the significance of 990-900 Ma orogenesis for the assembly of Rodinia? 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.Read moreRead less
Linkage Infrastructure, Equipment And Facilities - Grant ID: LE100100236
Funder
Australian Research Council
Funding Amount
$180,000.00
Summary
Facilities for spectroscopy and diffraction at high pressures. The provision of infrastructure for the study of novel materials under high pressures will enhance Australia's capability in creating new materials and in creating new devices that meet needs in communication, environment and medicine applications. The new facility will enable researchers to understand the response of structures to extreme pressures and will exploit the unique capabilities of the synchrotron light.
