A geological case for movement between Canada and Greenland along Nares Strait
Nares Strait, part of a 1400 km long lineament between Canada and Greenland, may be one arm (along with Lancaster Sound and Baffin Bay) of a triple junction. Study of the geological literature on the area from northern Baffin Island to northern Greenland revealed a number of possibly important marke...
