Edmonton Branch – Architecture of Upper Cretaceous Faulting
5:30 pm - 8:30 pm

Civil engineering considerations within the Great Plains Polygonal Fault System
The Great Plains Polygonal Fault System is an aerially extensive system of faulting that has been identified in Upper Cretaceous rocks at or near ground surface throughout an area that covers ~2,000,000 km. Faulting ranges from non-existent to faults with up to 80 m of vertical offset as interpreted using seismic data from southeastern Saskatchewan. An examination of outcrop and subsurface geology will be presented to discuss the potential ramifications for civil engineering in Alberta. The main point to be made is that the there is a continuity of pervasive faulting throughout the Great Plains area in fine-grained Upper Cretaceous rock.
The talk will cover many points including:
- A deposition model for Upper Cretaceous strata in the Great Plains.
- The cause of the faulting.
- Variability of strata such as bentonite within the faulted layers.
- Subsurface fault identification.
- Examples of faulting throughout the Great Plains area.
