Here we see the interaction between the Hearne
and the Rae Provinces. In the northeast, they are one on one along
the STZ, but farther south an opening is developing between them,
notwithstanding the simultaneous movements which, however, are oblique
to each other.
Some of the studies in the Alberta Basement transect are well advanced,
such as regional magnetic and gravity maps, and geochronological
investigations, even fluid movements. But others have only been
partially done, with a lot more to come, especially with respect
to deep seismic reflection surveys. So, we hesitate to include more
maps as several only will become available during the coming years.
