Sedimentary Depositional Cyclicity, Mission Canyon And Charles Formations (Mississippian), Williston Basin, North Dakota, Jean L. Hoff
Sedimentary Depositional Cyclicity, Mission Canyon And Charles Formations (Mississippian), Williston Basin, North Dakota, Jean L. Hoff
Theses and Dissertations
Workers within the Williston Basin have repeatedly reported the presence of sedimentary cyclicity within the carbonate and evaporite succession of the Mississippian Madison Group. Descriptions of cyclicity are diverse and commonly conflict. Previous work has been exclusively qualitative. This study used a group of statistical techniques in a method designed specifically for the objective identification and evaluation of cyclicity in the lithofacies sequence of the Mission Canyon and lower Charles Formations in North Dakota.
Twelve cores were sampled at every visually distinguishable lithologic unit. Forty-six lithologic components were counted in each sample on a presence-absence basis. The phi association coefficient …
Depositional Environments And Diagenesis Of The Lower Duperow Formation (Devonian), Billings Anticline, North Dakota, Randolph B. Burke
Depositional Environments And Diagenesis Of The Lower Duperow Formation (Devonian), Billings Anticline, North Dakota, Randolph B. Burke
Theses and Dissertations
The Duperow Formation is an Upper Devonian (Frasnian) subsurface unit in the Williston Basin in the north-central United States and south-central Canada. Despite its economic importance for hydrocarbons, no detailed accounts have been published on the Duperow Formation that integrate depositional environments, lithology, diagenesis, and pore studies on either a regional or local scale. It was the purpose of this study to construct a model of the depositional environments and diagenesis of the lower Duperow Formation in the Billings Anticline of west-central North Dakota, based on detailed analysis of 17 cores (225 m, 739 ft) and associated wireline logs and …
