This second edition of 'The Geology of England and Wales' is considerably expanded from its predecessor, reflecting the increase in our knowledge of the region, and particularly of the offshore areas. Forty specialists have contributed to 18 chapters, which cover a time range from 700 million years ago to 200 million years into the future. A new format places all the chapters in approximately temporal order. Both offshore and economic geology now form an integral part of appropriate chapters.

Stratigraphy is the key to understanding the geological evolution of the earth. It provides the framework for our interpretation of the sequences of events which have shaped the earth throughout its 4600 million years of existence. It provides the timescale with which we can determine the relative order of these events, and it provides the means whereby we can calibrate this using absolute ages in years. Stratigraphy is therefore the most fundamental subject in the science of geology, and all geologists are practising stratigraphers. Traditionally, however, stratigraphy has been considered as a Victorian science, a ponderous process of the naming and cataloguing of innumerable geological units most of which are of limited interest outside of a given geographical region. This view has been challenged in recent years through the development of new techniques such as sequence stratigraphy, cyclostratigraphy and chemostratigraphy which have greatly enhanced our capability to interpret earth history. In this book many of the leading practitioners of modern stratigraphy have been gathered together to provide up-to-date and authoritative reviews of most of the important advances in the subject. As such it is the only volume to provide a comprehensive treatment of modern stratigraphy at an advanced undergraduate level.

This volume contains a compilation of 17 seminal papers, taken from various Geological Society Special Publications and the Journal of the Geological Society, on the use and application of stratigraphy in petroleum geology over the last 20 years. The volume focuses on case studies in fundamental stratigraphy, applied and integrated stratigraphy and alternative methods of stratigraphy. The book is introduced with an original scientific and historical review of the subject: all papers are set in context with both the benefits of the techniques and some of the short-comings highlighted. By compiling these papers, commercial stratigraphers John Gregory, Philip Copestake and Julian Pearce have created a volume intended for a wide readership. However, it is of particular relevance for the training of undergraduate students studying courses on petroleum geology, basin development and sequence stratigraphy as well as for all postgraduate students working in petroleum-related scientific fields. It is also intended as a volume of general use for geoscientists entering the petroleum industry, as well as current workers requiring an overview.

The purpose of this book is to inform geoscientists about the progress made in scientific continental deep drilling as a new method for studying the continental crust. The Seeheim symposium was the second meeting organized for experts of the various national programs to present and discuss the results and progress made in their respective programs since the first symposium in Tarrytown in 1984. Various contributors dealt with the present state of - and experience in - deep drilling techniques as well as with the development of logging tools for drilling at high temperatures. Special emphasis was laid on the Continental Deep Drilling Program of the Federal Republic of Germany and its scientific aims.

Since the 3rd edition of this publication, emphasis within the petroleum industry has shifted from exploration to appraisal and development of existing hydrocarbon resources. This change is reflected in this new 4th edition, which has been significantly expanded to accomodate additional material. The centrepiece of the book, however, remains a series of descriptions, in stratigraphic order, of the depositional history and hydrocarbon related rock units of the North Sea.
