Lithostratigraphic Correlation Of The Coconino Sandstone (Permian) And Its Equivalents, Western United States, John H. Whitmore

Science and Mathematics Faculty Publications

The purpose of this study was to correlate Upper Paleozoic sandstone bodies of Pennsylvanian and Permian ages across the western United States. The cross-bedded Coconino Sandstone (Arizona) is perhaps one of the best-known formations in this collection of sandstones, many of which contain large cross-beds and thus are often interpreted as eolian in origin (McKee and Bigarella 1979). The Coconino Sandstone (Leonardian) is found in northern Arizona in places like Sedona and Grand Canyon.

Stratigraphic columns were obtained from multiple sources including the AAPG’s COSUNA charts and data, the RMAG’s Geological Atlas of the Rocky Mountain Region, and published papers …

Intraformational Parabolic Recumbent Folds In The Coconino Sandstone (Permian) And Two Other Formations In Sedona, Arizona (Usa), John Whitmore, Guy Forsythe, Paul A. Garner

Science and Mathematics Faculty Publications

We report sedimentary structures that in all ways resemble parabolic recumbent folds (PRFs) in the cross-bedded portions of the Schnebly Hill Formation, the Coconino Sandstone and the Toroweap Formation (Arizona, USA). Field evidence suggests they are penecontemporaneous and intraformational. Intraformational refers to deformation that occurs between undeformed beds. Recumbent cross-bed sets occur over a wide area (>375 km2 [144 mi2]) at many different locations and horizons in the Sedona area, especially within the Coconino Sandstone. Deformation resulting from slumping dunes (dry or damp) is ruled out because of the nature of the deformation along cross-bed dip, the size and …

The Petrology Of The Coconino Sandstone (Permian), Arizona, Usa, John Whitmore, Raymond Strom, Stephen Cheung, Paul A. Garner

Science and Mathematics Faculty Publications

The purpose of this paper is to give a description of the overall petrology of the Permian Coconino Sandstone that outcrops prominently in Arizona, including the Grand Canyon. The Coconino is often regarded as something like a “type” of the many similar Permian cross-bedded sandstones that occur around the world. It is generally accepted that the Coconino is an eolian sandstone and that its sand grains are well-sorted and well-rounded. However, until now, no detailed petrographic work has ever been published to substantiate these assumptions. We widely sampled the thickness and lateral extent of the formation and then studied hundreds …

Initial Conditions For A Post-Flood Rapid Ice Age, Steven M. Gollmer

Science and Mathematics Faculty Publications

In the early years of the modern creationist movement questions were raised as to the role of ice ages in explaining geological data. Beginning with Whitcomb and Morris (1961) and formalized by Oard (1979), a proposed scenario of warm oceans and volcanic activity would provide the needed conditions to initiate a post-flood ice age. During the 1990’s Vardiman used the Community Climate Model (CCM) to study the impact of warm oceans on global air circulation and precipitation patterns. Following Vardiman’s lead this study uses the Goddard Institute of Space Studies (GISS) Model E climate model. The first part of the …

Estimates Of Maximum Past Overburden For The Pierre Shale, Hayes Area, South Dakota, Thomas L. Rice

Science and Mathematics Faculty Publications

The Pierre Shale of the Northern Great Plains area of the United State is an Upper Cretaceous shale which was deposited in a marine environment. Geotechnically, the shale has been classified as an overconsolidated clay-shale. In South Dakota the Pierre Shale crops out extensively in the central and western portions of the state.

In this study an investigation was conducted for the purpose of clarifying and examining the existence of a discrepancy between geotechnically and geologically derived estimates of maximum past overburden for the Pierre Shale at Hayes, South Dakota.

The geological determination involved examining the topographic high points of …
