123:. The Hottah terrane, according to their dating evidence, share the same tectonic history as several domains south and east of it, domains that were tied to the Slave Craton ca. 1.97 Ga. The active margin in which the Hottah terrane was born began at ca. 2.0 Ga and lasted until ca. 1.85 Ga. During this period the terrane was transported laterally along the subduction system before colliding with the Slave Craton ca. 1.88 Ga. Renewed eastward subduction then resulted in the volcanism of the Great Bear magmatic arc ca. 1.876–1.869 Ga while plutonism lasted until ca. 1.855 Ga.
