Palaeomagnetism of Precambrian igneous rocks in Australia and East Antarctica: implications for the pre-Pangea supercontinents and supercontinent cycle
MetadataShow full item record
This thesis presents a series of new, high-quality palaeomagnetic data from Precambrian igneous rocks in Western Australia, South Australia and East Antarctica. The ages of the corresponding new palaeomagnetic poles range from late Archaean to late Mesoproterozoic. The new data improve significantly the Australian and East Antarctic palaeomagnetic database and shed lights on the tectonic evolution of Australia and global palaeogeographic reconstructions.

First Precambrian palaeomagnetic data from the Mawson Craton (East Antarctica) and tectonic implicationsLiu, Y.; Li, Zheng-Xiang; Pisarevskiy, Sergei; Kirscher, Uwe; Mitchell, R.; Stark, J. Camilla; Clark, Christopher; Hand, M. (2018)A pilot palaeomagnetic study was conducted on the recently dated with in situ SHRIMP U-Pb method at 1134 ± 9 Ma (U-Pb, zircon and baddeleyite) Bunger Hills dykes of the Mawson Craton (East Antarctica). Of the six dykes ...

Palaeomagnetism of the 1.89?Ga Boonadgin dykes of the Yilgarn Craton: Possible connection with IndiaLiu, Yebo; Li, Zheng-Xiang; Pisarevskiy, Sergei; Kirscher, Uwe; Mitchell, Ross; Stark, J. Camilla (2018)A palaeomagnetic study was carried out on the newly identified 1888 ± 9 Ma Boonadgin dyke swarm of the Yilgarn Craton in Western Australia. The Bonnadgin dykes yield a mean direction of magnetisation of D = 143°, I = 13°, ...
