Depositional Environments and Diagenesis of the Tensleep Sandstone, Eastern Big Horn Basin, Wyoming

Synthesis of late Paleozoic and Mesozoic eolian deposits of the Western Interior of the United States

“…Pennsylvanian eolian deposition is widespread and has been documented from the lower Casper Formation (Steidtmann, 1974), lower Tensleep Sandstone (Mankiewicz and Steidtmann, 1979;Kerr, this volume) and Quadrant Sandstone (Saperstone and Ethridge, 1984) in Wyoming and adjacent Montana and Colorado, in the lower Weber Sandstone of Utah, Wyoming and Colorado (Bissell and Childs, 1958;Driese and Dott, 1984), and from the Honaker Trail Formation of the Hermosa Group of southeastern Utah (Loope, 1984). In addition, eolian sandstone is present in the Manakacha and Wescogame Formations of the Supai Group in northern Arizona but has yet to be documented in the literature.…”

“…Figure 7A, B and C shows the Tensleep and related units in cross-section. Although the unit is renowned for exposures of large-scale, high-angle sand-flow strata that dip to the south and southeast (Steidtmann, 1974;Mankiewicz and Steidtmann, 1979), detailed sedimentologic studies have documented a broad variety of eolian stratification styles including small-scale trough and planar-tabular wind-ripple cross strata, horizontal to gently inclined wind-ripple strata, and wet and dry interdune deposits (Mankiewicz and Steidtmann, 1979;Driese and Dott, 1984;Saperstone and Ethridge, 1984;Kerr, this volume;J. Haslett, pets.…”

Impact of continental motion and dynamic glaciations on low-latitude climate during the Carboniferous: The record of the Wyoming Shelf (Western United States)

“…= Ranchester Limestone Member. Mankiewicz and Steidtmann, 1979;Moore, 1984;Kerr et al, 1986;Kerr and Dott, 1988;Carr-Crabaugh and Dunn, 1996;Hurley et al, 2003). A middle Pennsylvanian (Desmoinesian) age is well documented (Agatston, 1954;Henbest, 1954Henbest, , 1956 based notably on the fusulinids Wedekindellina sp.…”

Diagenesis of Paleozoic playa-lake and ephemeral-stream deposits from the Pimenta Bueno Formation, Siluro–Devonian (?) of the Parecis Basin, central Brazil

“…Playa-lake dolosparite was replaced by several phases of silica (microquartz, length-slow chalcedony and megaquartz). Silica is likely to have derived from the dissolution of silicate grains and clay minerals by high pH fluids, rather than as the result of local pressure dissolution, as indicated by the absence of sutured intergranular boundaries (Mankiewicz and Steidtmann, 1979;Moussavi-Harami and Brenner, 1993 …”

“…The Juruá Formation and other sandstones associated to sabkha deposits are important hydrocarbon reservoirs in several basins throughout the world (e.g. Glennie et al, 1978;Mankiewicz and Steidtmann, 1979;McBride, 1981;Pye and Krinsley, 1986;Dixon et al, 1989;Lee et al, 1989;Purvis, 1992;Gaupp et al, 1993;Gluyas et al, 1997;Amthor and Okkerman, 1998).…”
