INFORMATION TO USERS This manuscript has been reproduced 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.

ACKNOWLEDGMENTS I would like to express my sincere thanks to members of my dissertation committee, Dr. Roy Dokka, Dr. Joseph Hazel, Dr. Richard Kesel, Dr. Juan Lorenzo, Dr. C. M. Molenaar, Dr. Jeffrey Nunn, and Dr. Andrew Schedl, and especially my advisor, Dr. Dag Nummedal for their interest, encouragement, and constructive criticism. Dr. Dag Nummedal's guidance was most instrumental to the completion of this dissertation. Many of the ideas presented in this dissertation came about as the result of discussions and arguments with him. Because of his careful reviewing and editing, the structure and clarity of the manuscript has been greatly improved. Discussions with Dr. Andrew Schedl on many aspects of foreland basins were very helpful in early stages of this dissertation. Dr. Joseph Hazel taught me the essence of biostratigraphy and generously provided me his own research results. Dr. Jeffrey Nunn's knowledge of sedimentary basin mechanisms led to many significant improvements in the approach taken in this study. Discussions with Dr. Roy Dokka on many occasions were very constructive to the analysis of the subsidence data. His insights on the tectonics of foreland basins resulted in improvements in this dissertation. "K" Molenaar helped me in many ways throughout my work. Much of the subsurface data used in this dissertation was obtained with his help and guidance at the USGS at Denver. More important, his expertise and knowledge of the Cretaceous stratigraphy proved most valuable to the compilation of the stratigraphic data base of my work. Discussions with fellow students at LSU have also been constructive to this dissertation. In particular, I recognize with appreciation Drs. Greg Riley, Mark Pasley, Mr. Xiaogong Xie, and Mr. Mingji Chu for their interest and support of my work. I would like to thank all those extremely helpful people at the Office of the Department of Geology and Geophysics, especially Liz Keller and Thea Burchell. I wish to thank Drs. R. Johnson, K. Franczyk, T. Fouch, and T. Dyman of the USGS at Denver, each of whom contributed to my dissertation by making available their ii Reproduced with permission of the copyright owner.
