Long-lived connection between the North China and North Australian cratons in supercontinent Nuna: paleomagnetic and geological constraints

It has been proposed by Zhang et al.[1] that the northern part of the North Chirm Craton (NCC) was connected to the north-western part of the North Australian Craton (NAC) in the Proterozoic, mainly based on the radial geometry of correlative -1.32 Ga dyke swarms in the two cratons (Fig. la). While the hypothetical connection between the NCC and the NAC was thought to be paleomagnetically permissible at ~1.80- 1.78Ga but w让h a slightly different configuration [2], the exact duration of either configuration is uncertain (e.g.,[2,3]).
