...Jikai Ding; Shihong Zhang; Hanqing Zhao; David A.D. Evans; Kevin R. Chamberlain; Meinan Shi; Haiyan Li; Tianshui Yang; Huaichun Wu; Richard E. Ernst The timing and mechanisms by which the supercontinent Nuna broke up are still enigmatic, although the details have implications for global tectonic...

... supercontinents were stitched together. We utilize the orogenic belts spanning Baffin Island, Greenland and Fennoscandia that are inferred to record the assembly of the Paleoproterozoic supercontinent Columbia to test the accepted reconstruction of the Nuna core of Columbia. We show that as reconstructed...

... and Yilgarn cratons (1.3–1.1 Ga), where mineral formation was driven by plate reorganization following breakup of the Nuna supercontinent. This age correlation suggests that a combination of increased orogenic (+diagenetic) and heat (+fluid) generative processes resulting from supercontinent reconfiguration...

... supercontinent Nuna (also known as Columbia). Previous Nuna reconstruction models suggested that the WAC was connected to Amazonia in a way similar to their relative position in Gondwana. By an integrated paleomagnetic and geochronological study of the Proterozoic mafic dikes in the Anti-Atlas Belt, Morocco, we...

The Xiamaling Formation has been shown to exhibit depositional control by orbital cycles. Here, we tested the putative...
