Stability of salt in the Permian salt basin of Kansas, Oklahoma, Texas, and New Mexico, with a section on dissolved salts in surface water
George Odell Bachman, Ross Byron Johnson
1973, Open-File Report 73-14
The Permian salt basin in the Western Interior of the United States is defined as that region comprising a series of sedimentary basins in which halite and associated salts accumulated during Permian time. The region includes the western parts of Kansas, Oklahoma, and Texas, and eastern parts of Colorado and...
The Pine-Popple River basin — Hydrology of a wild river area, northeastern Wisconsin
Edward L. Oakes, Stephen J. Field, Lawrence P. Seeger
1973, Water Supply Paper 2006
The Pine and Popple Rivers, virtually unaltered by man, flow through a semiprimitive area of forests, lakes, and glacial hills. White-water streams, natural lakes, fish and animal life, and abundant vegetation contribute to the unique recreational and aesthetic characteristics of the area. Resource planning or development should recognize the interrelationships...
Water resources and geology of Mount Rushmore National Memorial, South Dakota
J.E. Powell, James Jennings Norton, D. G. Adolphson
1973, Water Supply Paper 1865
Ground water suitable for public supply can be obtained from fractured metamorphic and igneous rooks at Mount Rushmore National Memorial, S. Dak. The memorial comprises three main drainage basins: Starling basin, Lafferty Gulch basin, and East Boundary basin. Ground water is most prevalent in Lafferty Gulch basin but Starling basin contributes...
Stratigraphy and geologic history of the Montana group and equivalent rocks, Montana, Wyoming, and North and South Dakota
James R. Gill, William Aubrey Cobban
1973, Professional Paper 776
During Late Cretaceous time a broad north-trending epicontinental sea covered much of the western interior of North America and extended from the Gulf of Mexico to the Arctic Ocean. The sea was bounded on the west by a narrow, unstable, and constantly rising cordillera which extended from Central America to...
Glacial and postglacial geologic history of Isle Royale National Park, Michigan
N. King Huber
1973, Professional Paper 754-A
Isle Royale was overridden by glacial ice during each of the four major glaciations of the Pleistocene Epoch, and each successive glaciation essentially obliterated all direct evidence of preceding glaciations on the island. In the waning phase of the last major glaciation, the Wisconsin Glaciation, the frontal ice margin retreated...

1973, Massachusetts Hydrologic - Data Report 14
The Neponset, Weymouth Fore, and Weymouth Back River basins occupy an area of 183 square miles in eastern Massachusetts south of Boston and Braintree, Brockton, Canton, Dedham, Dover, Foxborough, Hingham, Holbrook, Medfield, Milton, Norwood, Quincy, Randolph, Rockland, Sharon, Stoughton, Walpole, Westwood, and Weymouth. Hydrologic data presented in this report were collected...
Chemical variation related to the stratigraphy of the Columbia River basalt
Thomas L. Wright, Maurice J. Grolier, Don Swanson
1973, GSA Bulletin (84) 371-386
Study of major element chemical analyses of Columbia River basalt leads to a grouping of most of the analyses into 11 chemical types which are distinguished with little overlap on a SiO2-MgO variation diagram. Other diagnostic variation diagrams are total iron (‘FeO’)-MgO, K2O-MgO, and TiO2-MgO.A four-unit informal stratigraphy has been...
Variations in Sr, Rb, K, Na, and Initial Sr87/Sr86 in Mesozoic Granitic Rocks and Intruded Wall Rocks in Central California
Ronald Wayne Kistler, Zell E. Peterman
1973, Geological Society of America Bulletin (84) 3489-3512
Initial Sr87/Sr86 of granitic rocks which are exposed north of the Garlock fault in California, and which represent the entire 130-m.y. time span of emplacement during the Mesozoic, ranges mainly from 0.7031 to 0.7082, with one value of 0.7094. A systematic areal variation, independent of age, exists for initial Sr87/Sr86 in these...
Nodal tidal cycle of 18.6 yr.: Its importance in sea-level curves of the east coast of the United States and its value in explaining long-term sea-level changes
Clifford A. Kaye, Gary W. Stuckey
1973, Geology (1) 141-144
The 18.6-yr cycle of the Moon's nodes dominates the annual means of high water, low water, and range at Boston and at other East Coast harbors. The maxima and minima of the high-water and range curves agree closely with the 180° and 0° long. yr, respectively, of the Moon's ascending...
Revised volcanic history of the San Juan, Uncompahgre, Silverton, and Lake City calderas in the western San Juan Mountains, Colorado
Peter W. Lipman, Thomas A. Steven, Robert G. Luedke, Wilbur Burbank
1973, Journal of Research of the U.S. Geological Survey (1) 627-642
The sequence of mid-Cenozoic volcanic events in the western San Juan Mountains is closely analogous to that elsewhere in the San Juan volcanic field. The Lake Fork, Picayune, and San Juan Formations were erupted from a cluster of central volcanoes from 35 to 30 m.y. ago, when dominant activity shifted to more silicic ash-flow eruptions...
Glauconites from New Jersey-Maryland coastal plain: Their K-Ar ages and application in stratigraphic studies
James P. Owens, Norman F. Sohl
1973, Geological Society of America Bulletin (84) 2811-2838
Glauconite samples from various stratigraphic levels in the northern Atlantic Coastal Plain were dated by the K-Ar method. Twenty-eight samples were collected from glauconite-bearing sands in four traverses across the outcrop belt of Upper Cretaceous–lower Tertiary formations from northern New Jersey to eastern Maryland, thus providing a framework on which...
