Cordilleria, a newly defined Canadian microcontinent

Abstract

Palaeomagnetic data and geological field evidence indicate that most of the western Canadian cordillera lay 1,500 km south of its present position in the early Cretaceous. We suggest that this region comprised a microcontinent, termed Cordilleria, which moved on the Kula plate and collided with the craton ˜100 Myr ago to form first the Mackenzie Mountains and then the Rockies.
