A piece of America found in northern Australia: Legacy of the 1.6-billion-year-old supercontinent Nuna
Throughout Earth’s 4-billion-year history, as continents shift around the globe, periods occur where the continents amass to form supercontinents. Most recently this occurred about 300 million years ago to form the supercontinent Pangea, where the southern continents (Africa, South America and Australia and Antarctica) were connected to Eurasia and North America. It is now recognised that a supercontinent termed Nuna formed about 1.6 billion years ago. Although previous researchers have speculated that north-east Australia was near North America, Siberia, or North China in Nuna, solid evidence have been hard to find from the ancient rocks.
In Australia, approximately two thirds of the country consist of basement rocks older than 600 million years. In North Queensland, 1.7 billion-year-old rocks are found in Mt. Isa and 500 km away in the Georgetown region. New sedimentological field data in conjunction with new and existing geochronological data from both regions revealed an unexpected constituent of the Australian continent.
PhD Student opportunities available!
Enjoy beaches, sun and working on a vast southern continent*? The ARC Australian Laureate Fellowship awarded to Z.X. Li, and Curtin University co-funding for both the Laureate Fellowship grant and the ARC Center of Excellence for Core to Crust Fluid Systems (CCFS), provide the opportunity for a number of PhD scholarships (for up to four years each) to work in the following fields.
- Palaeomagnetism and supercontinent reconstruction, with emphasis on Precambrian supercontinents. Field regions could be in Australia or overseas. (1 PhD position)
- Palaeointensity study in relation to supercontinent cycles, focusing on Precambrian mafic igneous rocks in Australia and elsewhere. (1 PhD position)
- 4D global to plate-scale geodynamic modeling using supercomputers. (1 PhD position)
- A study of oceanic Large Igneous Province (LIP) records in Australia and globally, involving case studies of accreted oceanic LIPs in pre-Cretaceous orogens in locations around the world. (potential PhD positions)
- Palaeo-Mesoproterozoic tectonostratigraphic analysis of the Yangtze Block. (potential PhD position)
