Sedimentary Rocks in the Field

Ideas and concepts in sedimentology are changing rapidly but fundamental field work and data collection remain the basis of the science. This book is intended as a guide to the recognition and description of sedimentary rocks in the field. It aims to help the geologist know what to observe and record and how best to interpret this data.

The emphasis is on illustrating the principal types of sedimentary rocks and the book contains over 400 superb colour photos and drawings. The introductory chapter defines the main types of sedimentary rock and their initial recognition, followed by a section highlighting safety in the field. The author goes on to describe the main field techniques and provides a comprehensive summary of the principal characteristics of sedimentary rocks. There is a chapter on each of the main rock types and on how to interpret facies and their features in terms of depositional environments and economic significance.

This book is of value to students, amateur enthusiasts and professional geologists.
