Petrology Of Sedimentary Rocks

This page intentionally left blank PETROLOGY OF SEDIMENTARY ROCKS SECOND EDITION Petrology of Sedimentary Rocks is an advanced textbook describing the physical, chemical, and biologic properties of the major types of sedimentary rocks, as revealed by petrographic microscopy, geochemical techniques, and field study. It covers the mineralogy, chemistry, textures, and sedimentary structures that characterise sedimentary rocks, and relates these features to the depositional origin of the rocks and their subsequent alteration by diagenetic processes during burial. In addition to detailed sections on siliciclastic rocks (sandstones, shales, conglomerates) and carbonate rocks (limestones and dolomites), it also discusses evaporites, cherts, iron-rich sedimentary rocks, phosphorites, and carbonaceous sedimentary rocks such as oil shales. This Second Edition maintains the fundamental structure of the original book, and presents a comprehensive treatment of sedimentary petrography and petrology. It has been thoroughly updated to include new concepts and ideas, and cutting-edge techniques such as cathodoluminescence imaging of sedimentary rocks and backscattered electron microscopy. Numerous photographs and diagrams illustrate characteristic features while an extensive and up-to-date reference list provides a useful starting point for additional literature research. This textbook is designed for advanced undergraduate and graduate courses in sedimentary petrology. It is also a key reference for researchers and professional petroleum geoscientists wanting to develop an understanding of the petrologic characteristics of sedimentary rocks and their geological significance. SAM BOGGS, Jr. received his Ph.D. from the University of Colorado and worked in the petroleum industry for a number of years before joining the University of Oregon, where he taught sedimentology and related subjects for more than 30 years, and where he continues his research in sedimentary petrology as a Professor Emeritus. He has also worked part-time as a research geologist for the US Geological Survey. Professor Boggs is a member of the Society for Sedimentary Geology (SEPM), the American Association of Petroleum Geologists, and the Geological Society of America. He is the author of two other books for Cambridge University Press – Backscattered Scanning Electron Microscopy and Image Analysis of Sediments and Sedimentary Rocks (1998) and Application of Cathodoluminescence Imaging to Study of Sedimentary Rocks (2006), as well as the author of four other books.
