Recent fieldwork, geochemistry, and U-Pb geochronology in the Palaeoproterozoic Ketilidian orogen provide substantial insights into the timing and mechanisms of its magmatic, sedimentary, and tectonic accretion. From north to south the orogen comprises an Archaean foreland and Border Zone, a calc-al...
