These documents are supplementary data for a manuscript submitted to Geophysical Research Letters entitled "Paleomagnetic evidence for a Paleoproterozoic rotational assembly of the North Australian craton in the leadup to supercontinent formation" by Kirscher et al. Short summary: Kinematics of the Paleoproterozoic assembly of Earth’s first supercontinent, are still debated. We present new paleomagnetic results from two Paleoproterozoic rock formations in the North Australia craton (NAC) that exemplify cratonic assembly processes in the leadup to Nuna formation. Our new paleomagnetic data for the 1825 Ma Plum Tree Creek Volcanics of the NAC and the layered mafic-ultramafic 1855 Ma Toby intrusion of the Kimberley Craton suggest their amalgamation just prior to ca. 1.8 Ga through a scissor-like ocean closure to form the NAC. Explanations for the supplementary tables are given in the supplementary material. 'directions_PCV': Comp: assigned component, 'C' component marks the used directions for calculating the site mean direction. 'D' represents alternative high temperature component (see table S2 for more explanation). directions_KIM': 'C' component marks the used directions for caluclating the site mean direction. 'C*"/'PLF' corresponds to components '*' and 'PLF' in table S1. |
