Depositional environments and diagenesis, Interlake Formation (Silurian), Williston Basin, North Dakota
… of about 1,100 feet in western North Dakota and thins to an erosional edge in eastern North Dakota, </p><p> The main purpose of this study was to interpret the depositional and diagenetic history of the Interlake Formation. Approximately 2,400 feet of Interlake core and 300 thin sections were …

Depositional environments and diagenesis of the Ratcliffe interval, Madison group (Mississippian), Williston Basin, North Dakota
… the Williston Basin. It is Mississippian in age and crosscuts the lower Charles and upper Mission Canyon Formations of the Madison Group. Study of cross-sections, well core, and thinsections show that the Ratcliffe is comprised of six major facies: 1) brachiopod-bryozoan-echinoderm …

Stratigraphy and sedimentology of the Tongue River formation (Paleocene), southeast Golden Valley County, North Dakota
… Golden Valley County, North Dakota were measured and described with particular emphasis on the Tongue River Formation. Lithologic samples were collected and analyzed for total carbonate content, particle size, particle roundness, and mineral composition. In the area studied, the Tongue River …

Paragenesis of Lacustrine Microbialites in the Upper Wilkins Peak Member, Green River Formation, Wyoming
… were investigated to determine their paragenesis and to help interpret lake chemistry. Two specific microbialite beds were analyzed that are associated with the “layered tuff”. Samples were collected from correlated sections along a NW to SE, 24 km line of section from lake margin towards lake …
