Marine Jurassic pelecypods from central and southern Utah

“…The positions of such geographic features may be found in the quadrangle maps of Utah and in the publications of Baker, Dane, and Reeside (1936); Gilluly (1929); Gregory (1950Gregory ( , 1951; Hardy (1952aHardy ( , 1962and Spieker (1946).…”

Geohydrology of the Navajo sandstone in western Kane, southwestern Garfield, and southeastern Iron counties, Utah

“…1). Displacement along the Sevier fault, in the western part of the study area, varies from less than 100 to as much as 2,000 ft (Gregory, 1951). Displacement generally decreases from south to north, and is 2,000 ft in Yellow Jacket Canyon, from 1,000 to 2,000 ft between Mt.…”

“…The hydrologic system of the Navajo Sandstone in the study area has been investigated by the State of Utah, the U.S. Geological Survey, coal company hydrologists, and private consultants, and several aspects of hydrologic properties and ground-water movement have been discussed in the reports resulting from these studies. Reports of particular interest to this investigation include those by Bingham Engineering (1973, 1974, 1979, 1981a, 1981b, and 1987); Blanchard (1986); ; Doelling and Graham (1972); Peltis (1966); Goode (1964; Gregory (1951); Hintze (1963); Sandberg (1979); and Todd (1987), because they contain most of the historic geologic and hydrologic data for the area. Hie reports by Bingham Engineering include descriptions of the hydrology, geology, and drilling program in the Navajo Sandstone conducted by the coal company.…”

“…Peltis (1966) and Goode (1964 provide earlier descriptions of the occurrence and movement of water in the Navajo Sandstone for this study area and for surrounding areas. Gregory (1951) and Hintze (1963) provide descriptions of the lithology, stratigraphy, and faulting that may affect the hydrology of the study area. Sandberg (1979) provides a hydrologic description of the area that is to be strip mined, and Todd (1987) documents the development of a three-dimensional ground-water flow model for the Kanab Creek drainage basin.…”

Isotopic ages and stratigraphy of Cenozoic rocks of the Marysvale volcanic field and adjacent areas, west-central Utah

“…The age of the Claron is poorly constrained, and because of the incidence of rare invertebrate fossils (Gregory, 1951) that suggested that lower parts are Eocene, we previously considered the formation to be Eocene and Oligocene . Goldstrand (1990), however, noted that palynomorph fossils in samples from basal Claron rocks from the eastern Pine Valley Mountains indicate a late Paleocene age for these rocks, whereas a fission-track date of 50±6 Ma that he determined from rocks collected just below the Claron contact in the Table Cliff Plateau indicates that there the basal Claron is Eocene.…”
