In the Purcell and Mackenzie mountains the supergroup unconformably overlies strata of the Purcell and Mackenzie Mountains supergroups, respectively. In and near the Omineca Belt the rocks unconformably overlie basement of granitic gneiss ranging in age from 728 Ma to more than 2 Ga (see Chapter 4).

In many places the supergroup is...
