Theses and Dissertations
This study of the Fermo-Pennsylvanian Minnelusa Group in North Dakota was designed to clarify the stratigraphy, illustrate association of depositional environments, and to relate the geologic history and economic potential of these strata.
The Minnelusa Group is defined here to include strata above the unconformity on the Madison and Big Snowy Groups and below the Opeche Formation. The Minnelusa Group in North Dakota contains the Tyler, Alaska Bench, Amsden and Broom Creek Formations. The Amsden has been divided into three marker defined lithozones designated, in ascending order, Medora, Dickinson, and Bismarck.
Drill and core samples were examined and described interpretively …
