Title: Cretaceous Deltas, Alberta: ABSTRACT

Author(s): C. R. Stelck

Article Type: Meeting abstract


End_Page 871------------------------------

Tectonic divisions of the Precambrian basement of Alberta seem to have exerted geographic control on the emplacement of major deltas of the late Mesozoic. The greater thicknesses of the Albian lower Blairmore delta coincide with the site (in Devonian time) of the west Alberta ridge and the Peace River "high." The thick parts of the latest Cretaceous Belly River and Edmonton deltas show similar disposition. The Dunvegan delta (Cenomanian) pinches out abruptly south of the Peace River arch. The Milk River delta (Campanian) is a feature of the Sweetgrass arch and the lower Edmonton tongue is limited to an area west of the same arch.

Hydrocarbon pools within these deltas are controlled by pre-Cretaceous erosion features and/or by shoreline facies.
