Principles of Sedimentology and Stratigraphy
This text is useful for intermediate/advanced level courses in Sedimentology, Stratigraphy, and Sedimentary Petrology. It presents a concise treatment of the fundamental principles of sedimentology and stratigraphy, including the processes that form sedimentary rocks, as well as describing the important physical, chemical, biological and stratigraphic characteristics of these rocks. The text emphasizes the ways in which the study of sedimentary rocks is used to interpret depositional environments, changes in ancient sea level, and other intriguing aspects of Earth history.

About Sam Boggs
In the early stages of his professional career, SAM BOGGS, JR., worked as a petroleum exploration geologist for Phillips Petroleum Company, searching for new oil fields in the Four-Corners region of the Rocky Mountains, prior to receiving his Ph.D. degree from the University of Colorado. He then worked for a time as a research geologist for Exxon Production Research Company before beginning an academic career. After joining the University of Oregon in 1965, he taught and carried out research in sedimentary petrology, stratigraphy, field geology, petroleum geology, and geological oceanography. During sabbatical leaves from the university, he served as a Scientist-in-Residence at the Argonne National Laboratory, University of Chicago, visiting professor at the Ocean Research Institute, University of Tokyo, and visiting professor at National Taiwan University's Institute of Oceanography. He was also employed part-time as a research geologist with the U.S. Geological Survey over a fifteen-year period. During his career, Dr. Boggs authored numerous scientific papers in sedimentary petrology, geological oceanography, stratigraphy, and low-temperature geochemistry. He is also author of four previous books. He currently lives in Eugene, Oregon, where he continues to do research as a Professor Emeritus at the University of Oregon.
