Contemporaneous assembly of Western Gondwana and final Rodinia break-up: Implications for the supercontinent cycle

Pre-Rodinia supercontinent Nuna shaping up: A global synthesis with new paleomagnetic results from North China

The existence of a pre-Rodinia Precambrian supercontinent, variously called Nuna or Columbia, has been widely speculated in the past decade, but the precise timing of its existence and its configuration have been uncertain due to the lack of unequivocal paleomagnetic and geological constraints. Here we report high-quality paleomagnetic results from the well dated 1780 Ma Xiong’er Group in south...

Age and Provenance of the Beardmore Group, Antarctica: Constraints on Rodinia Supercontinent Breakup

New U-Pb ages for detrital and igneous zircons constrain the depositional age and sedimentary provenance of the Beardmore Group, a siliciclastic succession that records transformation of the East Antarctic margin during Rodinia breakup and subsequent Gondwana amalgamation. We divide rocks previously mapped as the Beardmore Group into (1) an inboard late Neoproterozoic assemblage (probably ≤670 ...

The palaeomagnetically viable, long-lived and all-inclusive Rodinia supercontinent reconstruction

Palaeomagnetic apparent polar wander (APW) paths from the world’s cratons at 1300–700 Ma can constrain the palaeogeographic possibilities for a long-lived and all-inclusive Rodinia supercontinent. Laurentia’s APW path is the most complete and forms the basis for superposition by other cratons’ APW paths to identify possible durations of those cratons’ inclusion in Rodinia, and also to generate ...
