Hottah terrane

The Hottah terrane is a Paleoproterozoicterrane in the northwestern end of the Canadian Shield which is exposed near Hottah Lake, Northwest Territories. It is a belt of multi-deformed metasedimentary and metavolcanic rocks intruded by a series of diorite to graniteplutons. Forming the western part of the Wopmay orogenic system, the 1.9 Ga (billion years ago) Hottah terrane is separated from the Archean rocks of the orogen by the north-trending Wopmay fault zone and overprinted by the 1.875–1.85 Ga Great Bear magmatism.
