Aeromagnetic potential field map of western Canada. White lines denote seismic reflection profiles.

Note that patterns from the exposed rocks in the Shield can be followed below the sedimentary cover.
Let’s remember how units on the western side of the Trans-Hudson orogen dip into the Alberta Basement transect area. The geological cross section we just looked at runs about east to west near the southern edge of THOT. Follow this westward across the AB transect and we cover about 1,000 km as we cross the STZ. Within this distance we have two huge, once mighty and now eroded, mountain chains which comprise the THO and the Alberta orogen, which still is unnamed; its discovery is that new. By the way, what would YOU call the mountain chain in the Alberta Basement? Any suggestions? Think about it as we look the Alberta Basement over .
