文摘Supported on available paleomagnetic data,a new Columbia(Nuna)supercontinent reconstruction is proposed based on matching U-Pb-dated 1.79-1.75 Ga Large Igneous Province(LIP)mafic unit fragments and particularly on linking their dykes into radiating systems.Information from the literature is augmented with the herein dated 1762 Ma(U-Pb)Januária dyke swarm from the São Francisco Craton(Brazil).
