Title: Tectonics of Plains of Southern Alberta: ABSTRACT

Author(s): W. B. Gallup

Article Type: Meeting abstract


Structures having two different origins are present. One is associated with the Sweetgrass intrusives and may have developed in two stages, beginning with the early Laramide. Later crustal movements were the result of adjustment following the removal of a large block of sediments known as the Cypress prism during the late Tertiary. Such structures are relatively superficial.

The area is glaciated, outcrops are sparse, and additional information must come from drilling. New subsurface data will be of interest only if it is considered in the light of the knowledge that such structures do exist on the plains.
