... et al. (2012) , F.A. Macdonald et al. (2012) and Martel et al. (2012) . Bonnetia is a cryptic terrane represented by ca. 1.71 Ga igneous clasts in Wernecke breccias and inferred to have been accreted to northwestern Laurentia during the ca. 1.6 Ga Racklan orogeny. Timing of assembly and breakup...

... are imaged in crustal-scale seismic reflection data, and regional gravity and aeromagnetic datasets. Continental growth ( c. 1860–1850 Ma) along the southern margin of the proto-North Australian Craton is recorded by the accretion of a micro-continent that included the Aileron Terrane (northern Arunta...

... on supercontinent reconstructions ( Karlstrom et al., 2001 ). However, as studies of the 1710 Ma Bonnetia terrane in present-day northwest Canada have recently shown ( Furlanetto et al., 2013 ; Thorkelson and Laughton, 2016 ), not all late Paleoproterozoic magmatic arc assemblages accreted to the Laurentian margin...

... that culminated in the obduction of mafic volcanic rocks, remnants of an exotic arc terrane termed Bonnetia ( Nielsen et al., 2013 ; Furlanetto et al., 2016 ). Bonnetia terrane volcanic rocks obducted onto west Laurentia during the closure of the backarc basin likely correlate with the arc that rifted...

... of sediment-hosted Pb–Zn mineralization in the Mount Isa region with a view to better constraining its timing and relationship to global events. The Mount Isa terrane ( Fig. 2 ) lies wholly within the north Australian craton and is the world's largest single repository of Pb–Zn metal ( Huston et al...

.... The effect of secondary alteration on Sm–Nd isotopes similar to the dark grey rocks has also been demonstrated on Na- and K-metasomatized igneous clasts from the Paleoproterozoic Bonnetia volcanic arc terrane in Yukon ( Nielsen et al. 2013 ; their figs. 11 and 12 ). Both the PLV and the MIU have...
