&Quot;This Report is revised and expanded from the 1972 publication, providing an up-to-the-minute account of the British Ordovician formations and their correlation nationally and internationally. It also includes the most comprehensive treatment of Ireland ever attempted. The reference list is a comprehensive bibliography of papers on the subject published since 1970.". "This Special Report will be a valuable reference for research and applied geoscientists working with rocks of Ordovician age. It will be of particular interest to those working in, or visiting, the Welsh mountains and the English Lake District."--BOOK JACKET.

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.

The Ordovician was one of the longest of the geological periods, characterized by major magmatic and tectonic activity, an immense biodiversification, swings in climate and sea levels and the first Phanerozoic mass extinction. ‘A Global Synthesis of the Ordovician System’ is presented in two volumes in The Geological Society, Special Publications. This first volume (SP532) charts the history of the Ordovician System and explores significant advances in our understanding of its biostratigraphy, including more precise calibration of its timescale with tephra chronology and regional alignments using astrochronology and cyclostratigraphy. Changes in the world’s oceans, their shifting currents and sea levels, the biogeography of their biotas and the ambient climate are described and discussed against a background of changing palaeogeography. This first volume also includes syntheses of the Ordovician geology for most European countries, including historical key areas, such as Great Britain, Baltoscandia and Bohemia. The second volume (SP533) provides synthetic aspects of the Ordovician geology of most other parts of the world.

This text brings together multidisciplinary research and review papers on the Lower Palaeozoic geology of the Sierras Pampeanas and the Precordillera of central west Argentina. It deals with the final stages of assembly of the supercontinent of Gondwana and its tectonic interaction with Laurentia (the North American continent of today).
