Zircon ages from both belts range from 2.0 to 1.9 Ga and appear to record additions of juvenile crust. The match between the Archean Slave province in Canada and the Aldan province in Siberia also supports this fit. Common plutonic zircon ages in both provinces are >3.5 to 3.2 Ga, 3.1-2.9 Ga, and 2.8-2.6 Ga. The ∼1 Ga Grenville orogen may have extended northward between southern Greenland and Scandinavia, passing through east-central Greenland and adjacent Barentsia, and possibly into the Angara fold belt in Siberia. It is possible that three Early Proterozoic fold belts associated with the Aldan province are extensions of the Coronation Supergroup, an Early Proterozoic rift- to passive-margin succession deposited on the western margin of the Slave province.
