During the past two to three decades, the scanning electron microscope (SEM) has become established as an essential tool in the study of sedimentary rocks, sediments, and soils. It provides a useful complement to the traditional role of the petrographic microscope, which became popular after the pioneering work of Henry Clifton Sorby in the second half of the nineteenth century (Sorby, 1877a,b, 1878).

The process sedimentology of tills is crucial to the understanding of the glacier ice–bed interface as a complex depositional, erosional and shear boundary layer. Consequently, it also plays a central role in deciphering the genesis of enigmatic subglacial bedforms such as drumlins, flutings and ribbed terrain. Yet, unlike the study of other boundary layers such as those that operate at the bed of fluvial, aeolian and deep water systems, our knowledge of subglacial process–formrelationships is relatively impoverished, largely due to the inaccessibility of glacier and ice sheet beds.

Geology today demands the knowledge of a large number of fundamental ideas which are provided by neighboring sciences. The student, or the geologist at the beginning of his career, runs the risk of losing himself in a multitude of details and complications, which will seldom be useful to him. To guide him, we have endeavored to prepare a work which is easy to read, not overburdened with tables and graphs, and which avoids swamping the reader with all the details of many specialized disciplines. Our aim is to stress the general facts and to bring out the conclusions which will enable the reader to reconstruct the great events that have taken place in the past on the surface of the earth. <...>

This book is an outgrowth of my interest in the chemistry of sedimentary rocks. In teaching geochemistry, I realized that the best examples for many chemical processes are drawn from the study of ore deposits. Consequently, we initiated a course at The University of Cincinnati entitled "Sedimentary Ore Deposits," which serves as the final quarter course for both our sedimentary petrology and our ore deposits sequence, and this book is based on that teaching experience. Because of my orientation, the treatment given is perhaps more sedimentological than is usually found in books on ore deposits, but I hope that this proves to be an advantage. It will also be obvious that I have drawn heavily on the ideas and techniques of Robert Garrels.

Contourites are sediments deposited or substantially reworked by bottom currents. The study of contourites is nowadays crucial for several fields of fundamental and applied research:
1. palaeoclimatology and palaeoceanography, since these fairly continuous and relatively high-resolution sediments hold the key for priceless information on the variability in ocean circulation patterns, current velocities, oceanographic history and basin interconnectivity;

In October 1985, SEPM sponsored a four-day conference entitled "Sea-Level Changes—An Integrated Approach." The conference was organized by Everest Geotech, Inc., and hosted by Transco Exploration Company in Houston, Texas. Co-conveners of the conference were Dr. Cheryl Wilgus of Everest Geotech, Inc., Dr. Walter C. Pitman of Lamont-Dougherty Oceanographic Institute, and Dr. Christopher G. St. C. Kendall of the University of South Carolina.

Быть - может, многим из читателей случалось видеть море, то спокойное и блещущее торжественной красой, то бурное, мрачное и угрожающее, и иногда .задуматься о том, что скрывает под собою эта необъятная масса вод. Зто выражение — необъятная, вовсе не преувеличено.

The first edition of this book was conceived in 1974 to provide a comprehensive text, covering modern and ancient environments, suitable for advanced university students, research workers and professional geologists. To cover all environments and facies with the authority of an active research worker, we formed a group of authors who knew each other well and shared a similar philosophical view. We could criticize, amend and integrate each other's contributions, while retaining individual styles and responsibility for each chapter.
