Oblique Rae-Hearne collision.

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.
