Shales and mudstones are the most poorly understood sedimentary rock type. They comprise approximately two thirds of the stratigraphic column and contain the bulk of recorded earth history. In the future, understanding shales will be crucial for a wide variety of studies. Yet, getting a balanced perspective of research on these fascinating rocks is difficult because it is dispersed over so many subdisciplines. The two volumes of this book present up to date research on a wide range of topics in shale geology, and were assembled with the goal to ease access to this engaging field of research. Chapter introductions were written by experts in their field, and are intended to define the state of the art, to provide access to pertinent literature, and to set the stage for the corresponding research papers. Volume I covers basin-scale analysis, sedimentology and paleontology of shales. Volume II supplements this perspective with detailed treatments of petrography, burial history, petrophysics, geochemistry, and economic aspects of shales. The broad coverage of topics should make this book a valuable source of information for those that want to keep informed about current developments in shale research, and a source of inspiration for those interested to enter this exciting field of study.

The Colorado Group is the thickest and most regionally extensive succession of Cretaceous rocks in the Western Canada Sedimentary Basin. Colorado Group shales contain proven source rocks and hydrocarbon reserves, yet the details of their origin, composition, distribution, and maturity are largely unknown. This report presents research undertaken to address this knowledge gap and to identify distinct shale units in the studied interval, evaluate the depositional & facies controls on shale composition, and provide quantitative mineralogy & bulk chemical properties that may be used for wireline calibration and source rock & reservoir characterization. The research consisted of a basin-scale multidisciplinary study that refines the Cretaceous shale stratigraphy and provides a regional basis for further detailed exploration & exploitation of Colorado Group hydrocarbon & mineral resources. The study integrates geochemical, biofacies, and sedimentological data to identify discrete shale formations within the previously undifferentiated Group. Detailed geochemical and facies analyses provide new information on source-rock distribution and maturity. Results are also presented from pyrolysis & mineralogical studies, paleoenvironmental reconstructions, and identification of diagenetic processes.

A Comprehensive review of modern stratigraphic methods. The stratigraphic record is the major repository of information about the geological history of Earth, a record stretching back for nearly 4 billion years. Stratigraphic studies fill out our planet’s plate-tectonic history with the details of paleogeography, past climates, and the record of evolution, and stratigraphy is at the heart of the effort to find and exploit fossil fuel resources. Modern stratigraphic methods are now able to provide insights into past geological events and processes on time scales with unprecedented accuracy and precision, and have added much to our understanding of global tectonic and climatic processes. It has taken 200 years and a modern revolution to bring all the necessary developments together to create the modern, dynamic science that this book sets out to describe. Stratigraphy now consists of a suite of integrated concepts and methods, several of which have considerable predictive and interpretive power. The new, integrated, dynamic science that Stratigraphy has become is now inseparable from what were its component parts, including sedimentology, chronostratigraphy, and the broader aspects of basin analysis.
