1-The Wopmay orogen is a palaeoproterozoic orogenic belt in northern canada which formed during the collision between Hottah terrane.Basic features which are typical of orogenic belt are continental magmatic arc,archean slave craton.
The Wopmay can be subdivided into a passive continental margin,the Wopmay fault zone,the magmatic zone and hottah terrane.the Wopmay Fault zone is the suture between slave craton and Hottah terrane which is a basic feature of an orogenic belt,in orogenic belt fault zone,continental margin ,magmatic zone etc. Are present which is present in Wopmay orogen.
