The Key to Earth History

The Key to Earth History An Introduction to Stratigraphy Peter Doyle Matthew R. Bennett and Alistair N. Baxter School of Earth Sciences, University of Greenwich, UK The Key to Earth History is the first textbook on stratigraphy to introduce the student to the basic tools used by geologists to reconstruct Earth?s history, as well as showing how these can be utilised to chart the pattern of global environmental change which has taken place since the formation of the Earth some 4600 million years ago. Divided into two sections, the book discusses how stratigraphy is the key to understanding the history of the Earth, and how it can be used as a dynamic tool in unravelling ancient Earth environments. The first part examines the basic stratigraphical methods used to establish, date and interpret sequences of rocks as the products of a series of events in the Earth?s history. The second part of the book presents the results obtained by geologists, who have used these stratigraphical tools in order to build up a record of the way in which the Earth?s global environment has changed through geological time. The reader is introduced to these concepts through the use of boxes highlighting key points, together with international case histories, and this user-friendly approach will ensure that The Key to Earth History is essential first-year reading for geology, environmental science and geography undergraduates.
