Theses and Dissertations
Pressure-solution features of the Birdbear Formation (Devonian), Williston Basin, North Dakota were the subject of this study. In the area studied, the Birdbear Formation is primarily a limestone with mud-rich textures. The investigation contained three principal phases: 1) a study of the parameters influencing the size and shape of the pressure-solution response, 2) the process of reactate dolomite formation and its relation to calcite neornorphism, and 3) the relation of neomorphism to pressure solution.
The principal pressure-solution response types are stylolites and solution seams. Stylolites are pressuresolution seams with a tooth-and-socket, serrated shape. Pressure-solution seams are gently undulating to smooth …
