Hottah terrane
Paleoproterozoic terrane in the northwestern end of the Canadian Shield
The Hottah terrane is a Paleoproterozoic terrane 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 granite plutons.[1] 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.[2]
