• Format: ePub

Produktbeschreibung

Sedimentology and Stratigraphy Comprehensive textbook on all aspects of sedimentology and stratigraphic principles Sedimentology and Stratigraphy introduces the reader to the subjects and provides tools for the interpretation of sediments and sedimentary rocks, covering the processes of formation, transport, and deposition of sediment and applying them to develop conceptual models for the full range of sedimentary environments, from deserts to deep seas and reefs to rivers. Different approaches to using stratigraphic principles to date and correlate strata are also considered to provide a comprehensive overview of all aspects of sedimentology and stratigraphy. The 3rd edition has been thoroughly revised and updated. The book is now divided into five sections, and the chapters on different depositional settings now provide distinct sections on modern processes and sedimentary rocks. The new edition also features a new set of diagrams and photographs in full colour. Key concepts introduced in Sedimentology and Stratigraphy include: * The importance of changes in plant and animal life through time and the effects on characteristics of both marine and continental sedimentary environments * The distinction between modern environments and what is preserved in the sedimentary record * The role of changing climate, tectonic events and sediment supply in determining the characteristics of deposits in the stratigraphic record Written by a highly qualified author with abundant experience in the field, Sedimentology and Stratigraphy serves as a highly accessible resource for students of geology and related subjects who seek to understand the formation, characteristics, and importance of sedimentary rocks.

Autorenporträt

Gary Nichols has taught sedimentology and stratigraphy at universities in the UK and Norway. His research interests in the analysis of facies and sedimentary basins have taken him to every continent, providing experience of a wide range of sedimentary rock types of different ages in a variety of depositional settings. He currently designs training programmes for geoscientists working in the energy industry.
