Lithostratigraphic Correlation Of Upper Paleozoic Sandstone Bodies In The Western United States With Special Emphasis On The Coconino Sandstone, John H. Whitmore
Lithostratigraphic Correlation Of Upper Paleozoic Sandstone Bodies In The Western United States With Special Emphasis On The Coconino Sandstone, John H. Whitmore
The Research and Scholarship Symposium (2013-2019)
The purpose of this project was to correlate Upper Paleozoic sandstone bodies of Pennsylvanian and Permian age across the western United States. The lateral extent of the Coconino Sandstone (Leonardian) was of particular interest; it is found in northern Arizona in places like Grand Canyon. Data was 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 from a variety of books and journals. About 60 generalized stratigraphic columns were collected, drawn and then correlated across the western United States. Some of the more well-known sandstones and …
Preliminary Correlation And Isopach Map Of Pennsylvanian And Permian Sandstones Of The Western United States, John H. Whitmore
Preliminary Correlation And Isopach Map Of Pennsylvanian And Permian Sandstones Of The Western United States, John H. Whitmore
The Research and Scholarship Symposium (2013-2019)
Using the COSUNA data compiled by the AAPG in the 1980’s, Permian and Pennsylvanian sandstones were correlated across western North America. Stratigraphic sections and thickness information were obtained from charts and spreadsheets available from that data set. An isopach map was constructed from the thickness data of sandstones usually found below a Guadalupian Limestone. In particular, this project was concerned with sandstones that could be lithostratigraphically correlated with the Leonardian Coconino Sandstone of the Grand Canyon region of northern Arizona. These sandstones are mostly Lower Permian (Leonardian and Wolfcampian) but some are Upper Pennsylvanian, especially in the northern part of …
