And last, but not least, a very spe­ cial thank-you to the one who gave the most of all, Gerd, my son. vi ABSTBACT This lexicon of bedrock stratigraphic names of North Dakota consists of a general definition of each unit as well as the history of stratigraphic nomenclature, An attempt was made to include all units for North Dakota whether form.ally or informally named, or cur­ rently being used in the state. The general definition includes name(s) of the unit, age, area of extent, lithology, relationships to other units, characteristic fossils, economic significance, depo­ sitional environment, type section (1£ one has been proposed), and other remarks that might be significant. The history of strati­ graphic nomenclature includes a chronological listing of the first definition of the unit and any changes that occurred subsequent to the introduction of the unit. The lexicon includes approximately 350 ter!l!S. Of these, 1% is in the Cambrian System, 6% are in the Ordovician, 1% is in the Silurian, 10% are in the Devonian, 12% are in the Mississippian, 3% are in the Pennsylvanian, 3% are in the Permian, 1% is in the Triassic, 7% are in the Jurassic, 24% are in the Cretaceous, and 32% are in the Tertiary System. vii INTRODUCTION Purpose In the past two decades, the geology of North Dakota has been receiving much attention. The economic potential of the Williston basin has motivated this attention, as well as the academic interest by North Dakota's universities, the North Dakota Geological Survey, and the United States Geological Survey. Therefore, a need has devel­ oped for a lexicon of the bedrock stratigraphic units of the state. This lexicon provides an organized list of well-known units and their definition and evolution, as well as less well-known terms and local terms in an attempt to make this lexicon of use to as many people as possible. The academic geologist, economic geologist, and any person interested in stratigraphy should find this lexicon of use. Quaternary units are not included in this lexicon because, only recently, have stratigraphic studies been extended to include this part of the column. Consequently, these units are in a state of confusion because their relationships are not clearly understood. Methods An incomplete preliminary list of stratigraphic units was determined by examining publications, primarily of the North Dskota Geological Survey, that contained sections on stratigraphy. The Lexi­ con of Geologic Names of the United States (Wilmarth, 1938, and Kercher, 1966, 1970) and Changes in Stratigraphic Nomenclature of the U. S. 1 2 Geological Survey (Cohee, Bates, and Wright, 1970a, 1970b; and Cohee and Wright, 1972, 1974, 1975a, 1975b, 1976; and Sohl and Wright, 1977) were consulted for the history of stratigraphic nomenclature of each unit, A Guide to the Stratigraphy of South Dakota (Agnew and Tychsen, 1965), and Catalog of Stratigraphic Names for Montana (Balster, 1971) were reviewed for further references for the history of stratigraphic nomen­ clature and also for any additional stratigraphic terms for North Dakota. The Annotated Bibliography of the Geology of North Dakota, 1806-1959 (Scott, 1972), Bibliography and Index of Geology (Geological Society of America, 1971, 1972, 1973, 1974, 1975, 1976, 1977), and Bibliography of North American Geology (U.S. Geological Survey, 1918-1973) were used to determine additional entries for the history of stratigraphic nomencla­ ture. The bibliography of each of these publications was also examined for references that may have been missed. University of North Dakota theses and dissertations were reviewed for unpublished information that may be pertinent. Personnel of the North Dakots Geological Survey also provided local drillers' terms that had not been noted in the literature, The literature determined from the above sources was read for the general definition and history of stratigraphic nomenclature. The general definition includes, where applicable, all names of the strati­ graphic unit, age, areal extent, lithology, thickness, relationships to other units, characteristic fossils, type section, and other more sub­ jective items such as economic potential, depositional environment, and suck other remarks that may be pertinent. All parts of the definition were derived exclusively from the literature with no personal interpre­ tations entered. 3 Nearly all bedrock units occur essentially throughout the Williston basin but a neighboring state or province may not use the same name for the same unit; lithologies also change from one area ta another possibly resulting in a multiplicity of names for a single unit, Crass-references are included to alleviate possible confusion, The thickness of a unit refers to the maximum thickness in North Dakota. The thickness at the type section was also given if it sig­ nificantly differed from the thickness in the state. Relationships of a unit to other units refers to whether the contacts of overlying and underlying units are conformable or unconformable, Lateral equiva­ lents are also given if known, Characteristic fossils are listed for units where they are known. Only the economic significance as given in the literature was included in the general definition. If no eco­ nomic significance is indicated, the unit may still be valuable as a natural resource but its value has not been discussed in publication. Depositional environment, too, is indicated only if it has been dis­ cussed in print, The type section is listed if one has been formally proposed according to the Code of Stratigraphic Nomenclature (American Commission on Stratigraphic Nomenclature, 1972). Otherwise, the infor­ mal type area has been included under the remarks section.

  • South Dakota to Nebraska
    Geological Society of America Special Paper 325 1998 Lithostratigraphic revision and correlation of the lower part of the White River Group: South Dakota to Nebraska Dennis O. Terry, Jr. Department of Geology, University of Nebraska—Lincoln, Lincoln, Nebraska 68588-0340 ABSTRACT Lithologic correlations between type areas of the White River Group in Nebraska and South Dakota have resulted in a revised lithostratigraphy for the lower part of the White River Group. The following pedostratigraphic and lithostratigraphic units, from oldest to youngest, are newly recognized in northwestern Nebraska and can be correlated with units in the Big Badlands of South Dakota: the Yellow Mounds Pale- osol Equivalent, Interior and Weta Paleosol Equivalents, Chamberlain Pass Forma- tion, and Peanut Peak Member of the Chadron Formation. The term “Interior Paleosol Complex,” used for the brightly colored zone at the base of the White River Group in northwestern Nebraska, is abandoned in favor of a two-part division. The lower part is related to the Yellow Mounds Paleosol Series of South Dakota and rep- resents the pedogenically modified Cretaceous Pierre Shale. The upper part is com- posed of the unconformably overlying, pedogenically modified overbank mudstone facies of the Chamberlain Pass Formation (which contains the Interior and Weta Paleosol Series in South Dakota). Greenish-white channel sandstones at the base of the Chadron Formation in Nebraska (previously correlated to the Ahearn Member of the Chadron Formation in South Dakota) herein are correlated to the channel sand- stone facies of the Chamberlain Pass Formation in South Dakota. The Chamberlain Pass Formation is unconformably overlain by the Chadron Formation in South Dakota and Nebraska.

A. Munter G. A. Ludvigson B. J. Bunker Iowa Geological Survey Iowa Geological Survey Donald L. Koch Director and State Geologist 123 North Capitol Street Iowa City, Iowa 52242 Foreword An assessment of the quantity and quality of water available from the Dakota (Sandstone) Formation 1n northwest Iowa is presented in this report. The as sessment was undertaken to provide quantitative information on the hydrology of the Dakota aquifer system to the Iowa Natural Resources Council for alloca tion of water for irrigation, largely as a consequence of the 1976-77 drought. Most area wells for domestic, livestock, and irrigation purposes only partial ly penetrated the Dakota Formation. Consequently, the long-term effects of significant increases in water withdrawals could not be assessed on the basis of existing wells. Acquisition of new data was based upon a drilling program designed to penetrate the entire sequence of Dakota sediments at key loca tions, after a thorough inventory and analysis of existing data. Definition of the distribution, thickness, and lateral and vertical changes in composition of the Dakota Formation has permitted the recognition of two mem bers. Additionally, Identification of the rock units that underlie the Dakota Formation has contributed greatly to our knowledge of the regional geology of northwest Iowa and the upper midwest.

  • Petroleum Geochemistry of the Lower Cretaceous
    Petroleum Geochemistry of the Lower Cretaceous Mannville and Jurassic Ellis Groups, Southern Alberta, Canada Kim Manzano-Kareah *, Shell International Exploration and Production, Houston, USA [email protected] The variation of oil quality in southern Alberta, Western Canada Sedimentary Basin, Canada is primarily due to differences in oils generated from different source rocks and biodegradation of oils in reservoirs. 280 oil samples were collected and analysed by GC and GC-MS, in order to assess the nature and extent of these petroleum systems. Oils from Lower Cretaceous Mannville and Jurassic Ellis Group reservoirs in southern Alberta, Canada (T1-40; R1-25W5) were generated from at least five different source rocks. The proven/probable source rocks include: the Devonian Duvernay Formation (Family D), the Devonian-Mississippian Exshaw Formation (Family E), a probable Paleozoic source (Family M), a probable Jurassic source (Rierdon/Fernie shales; Family F), and the Cretaceous Ostracod Zone (Family Q). Family D oils are restricted to the northernmost part of the study area (Provost field). Biodegradation and the mixing of degraded with non-degraded oils are the main factors controlling the variation in oil quality within a given family. The much improved understanding of oil families and degree of biodegradation allow for more accurate mapping of likely oil migration pathways. Known reservoir trends, subcrop edges, structure, hydrodynamics, the distribution and quality of known oil pools can all be integrated into mapping migration paths. This allows for more accurate mapping of likely oil and gas migration pathways, which can be used for prospect risking and for the ranking of exploration plays.
