Allostratigraphy and Biostratigraphy of the Upper Cretaceous (Coniacian-Santonian) Western Canada Foreland Basin

About this book

This bulletin contains three closely integrated papers that treat Upper Cretaceous (Coniacian-Santonian) strata of the Western Canada Foreland Basin (WCFB). It presents the results of 12 seasons of geological feldwork in the Rocky Mountain Foothills of Alberta. The outcrops were measured in detail, with particular attention to depositional cycles and bounding surfaces that indicate relative changes in sea level. Fossils of molluscs were collected at each locality and placed precisely within each section. The results of these outcrop investigations were integrated with a public database comprising thousands of wireline logs, supplemented by cores, which provided the regional control to reconstruct the stratal geometry, facies relationships, and paleogeography of the basin in three dimensions. The principal purpose of this research is to present a detailed allostratigraphic and biostratigraphic framework for the Coniacian and basal Santonian succession in the WCFB.
