Long-lived connection between the North China and North Australian cratons in supercontinent Nuna: paleomagnetic and geological constraints
|
摘要
<正>It has been proposed by Zhang et al.[1]that the northern part of the North China 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.1a).While the hypothetical connection between the NCC and the NAC was thought to be paleomagnetically permissible at～1.80-1.78 Ga but with a slightly different configuration[2],the exact duration of either configuration is uncertain(e.g.t[2,3]).Here we present a comparison of
