CAMBRIAN-EARLY ORDOVICIAN SEQUENCE STRATIGRAPHY AND MOUNT SIMON SANDSTONE PETROLOGY-MICHIGAN BASIN by Jeffrey T. Cottingham A Thesis Submitted to the Faculty of The Graduate College in partial fulfillment of the requirements for the Degree of Master of Science Department of Geology Western Michigan University Kalamazoo, Michigan December 1990 Reproduced with permission of the copyright owner. Further reproduction prohibited without permission. CAMBRIAN-EARLY ORDOVICIAN SEQUENCE STRATIGRAPHY AND MOUNT SIMON SANDSTONE PETROLOGY-MICHIGAN BASIN leffrey T. Cottingham, M.S. Western Michigan University, 1990 Michigan subsurface correlation is complicated in the Cambrian-Early Ordovician section due to limited availability of rock data. Core and cuttings examination demonstrate that similar stratigraphic sequences exist between the Michigan Basin and surrounding regions. Lithofacies in Wisconsin outcrop are similar to their basinal counterparts, and are correlated on the basis of sediment types, sedimentary structures, and the sequence stratigraphic concept. The Mount Simon Sandstone in Michigan correlates with that observed in Illinois, Wisconsin, and Iowa. Isopach data throughout the Midwest indicate a single depocenter in Northeastern Illinois. Sedimentary structures and lithology indicate a subtidal environment that may be a progradational transition from a lower (shoreward) aeolian environment. Observed diagenetic patterns are influenced primarily by depth of burial. The deep pattern (below 14,250’) exhibits extreme compaction. The shallow pattern (above 8900’) exhibits pervasive carbonate and quartz cements, and authigenic clays. Secondary porosity developed from dissolution of carbonate, feldspar, and quartz.

ACKNOWLEDGEMENTS The author is deeply indebted to the following people for support and guidance throughout the work on this project: My advisor, Dr. William B. Harrison HI, who has remarkable insight into subsurface stratigraphy; Dr. David A. Barnes and Dr. W. Thomas Straw of Western Michigan University, and Dr. Richard Anderson of Augustana College, Rock Island, Illinois, all of whom served on the thesis committee; Dr. Charles Byers of the University of Wisconsin-Madison, Michael Sargent and Joan Crockett of the Illinois State Geological Survey in Urbana, who provided significant insight into the regional perspective; Randall L. Milstein of the Michigan Department of Natural Resources- Geological Survey in Lansing, who provided well data that aided in the compilation of wells and formation tops presented here; and John Fowler, who dropped by the Core Lab from time to time, and always provided input and insight.

INFORMATION TO USERS The most advanced technology has been used to photograph and reproduce this manuscript from the microfilm master. UMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer. The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction. In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand corner and continuing from left to right in equal sections with small overlaps. Each original is also photographed in one exposure and is included in reduced form at the back of the book. Photographs included in the original manuscript have been reproduced xerographically in this copy. Higher quality 6" x 9" black and white photographic prints are available for any photographs or illustrations appearing in this copy for an additional charge. Contact UMI directly to order.
