HILMES Dr. Robert L. Bauer, Thesis Supervisor MAY 2014 The undersigned appointed by the Dean of the Graduate School, have examined the thesis entitled 2D AND 3D MODELING OF THE LARAMIDE FOLD GEOMETRY OF DERBY DOME AND ITS EN ECHELON INTERCHANGE WITH DALLAS DOME, SOUTHERN WIND RIVER BASIN, WYOMING Presented by Michael J. Hilmes A Candidate for the degree of Master of Science, And hereby certify that in their opinion it is worthy of acceptance. _______________________________________________________ Professor Robert L. Bauer _______________________________________________________ Professor Eric Sandvol _______________________________________________________ Professor Erik J. Loehr Acknowledgements First and foremost I would like to thank my advisor Dr. Robert Bauer for all of his support, patience, insight, and encouragement to help me through my research project. I’ve learned a great deal from him and the knowledge he’s provided me is invaluable. I would like to thank Dr. Eric Sandvol for his encouragement and advice, and for his help with the setup and completion of the seismic reflection experiment. I would also like to extend my thanks to Dr. Erik Loehr for agreeing to be on my defense committee. I would like to thank the University of Missouri-Columbia Department of Geological Sciences for the education, the teaching assistantship that funded my education, and for welcoming me into the department (even though I’m from Kansas). Funding for the field work completed during summer 2013 was provided by a grant from the Geological Society of America (GSA) Graduate Student Research Grants Program. These funds were instrumental in offsetting the cost of various necessities associated with the field work. A very special thanks goes out to Dr. Miriam Barquero-Molina for always being a positive force in the department and extending her passion for geology to her students. I would like to thank her and the rest of the University of Missouri Branson Field Laboratory for the living accommodations as I completed my field work. I also owe a great deal of thanks to the students at the Branson Field Laboratory for their assistance in setting up and conducting the seismic reflection experiment. Thanks to Mark Sutcliffe and Newfield Exploration for providing the well data for the modeling portion of the study, and thanks to Chris Brocka for his assistance with his research materials. I would also like to thank Jenny Ellis and especially Oskar Vidal ii Royo from Midland Valley for their advice and technical support with the Move® software. Finally, I would like to thank my friends and family. Without them, none of this would be possible. iii TABLE OF CONTENTS ACKNOWLEDGEMENTS……………………………………………….….............…ii LIST OF FIGURES…………………………………………………………….….....…vii LIST OF

Principal component analysis of the data suggests that the smaller footprints from the Valtos Sandstone and Kilmaluag formations are indistinguishable from the footprints of the Sundance Formation. The single footprint from the Lealt Shale Formation is similar to the larger footprints from the Valtos Sandstone Formation. The footprints from the Duntulm and Gypsum Springs formations form distinct groupings from all other footprints. Four different groupings of dinosaur footprints can be recognized from the principal component analysis that may represent at least four different types of dinosaur.

  • TIES, MONTANA. by CF BOWEN. Previo
    ANTICLINES IN A PART OF THE MUSSELSHELL VALLEY, MUSSELSHELL, MEAGHER, AND SWEETGRASS COUN­ TIES, MONTANA. By C. F. BOWEN. INTRODUCTION. Previous investigations had shown that the Musselshell Valley, Mont, is an area in which the rocks have undergone considerable folding. On the basis of this information work was begun in June, 1916, to determine the nature and extent of the folds and to make examination as to the possible occurrence of accumulations of oil and gas in them. The work has demonstrated the existence within the area studied of several well-developed anticlines and domes, which seem to offer structurally favorable places for the accumulation of oil and gas. The demonstration of the presence or absence of commercial accumulations of these fluids in the folds has been less conclusive, owing largely to the undeveloped condition of the area. No direct surface indications of oil were observed, but hydrogen sulphide gas escapes from several water seeps in one part of the area. It is also reported that gas was encountered in several wells dug for water. None of these reports could be verified. At the time of the examination drilling operations within the area were confined to two wells. One of these wells, on the Big Elk dome, had reached the Kootenai formation; the other, in the Woman's Pocket anticline, was probably somewhat more than halfway through the Colorado shale. In neither place had oil been discovered. Two other wells, one about 15 miles east of the area and the other about 12 miles south of the central portion of it, had previously been drilled through the Colo­ rado shale without any discovery of oil.
