After 19th-century controversy and an absence of 100 years, the work of remapping this area of Snowdonia was begun by the Geological Survey who gave special attention to the volcanic rocks of the Ordovician succession. Using the stratigraphy established by the detailed 1:10,000 mapping as a basis, a major geochemical study of the volcanic rocks has been accomplished alongside multi-disciplinary studies of sedimentology, physical volcanology, palaeontology, structure and metamorphism. The great age of this volcanic province, subsequent tectonic events, uplift and erosion have allowed the study to encompass all stages from its birth, through its maturity into its lingering death, in a way that is denied those analyzing younger activity. This book represents an advance in our understanding of volcanic processes in marine environments, acidic ash-flow tuffs in subaerial and subaqueous settings, tectonic controls on volcanism and sedimentation and petrogenetic modelling.

Stratigraphers and sedimentologists who are presently describing and interpreting the infill of sedimentary basins are generally agreed that it is difficult to disentangle the signatures of tectonic processes from those of climate and eustatic sea level change in the resultant rock succession. Until better criteria are developed to distinguish between the roles played by the major variables, it is still most useful to document and interpret basin-fill architectures where we know, from independent evidence, that one of the main controls is likely to have been a major contributor. This book contains a collection of papers describing situations where the tectonic setting is fairly well established, and it can be assumed that at least the tectonic factor has contributed to the resultant signatures.

This book presents the geomorphological diversity of England and Wales. These regions are characterised by an extraordinary range of landforms and landscapes, reflecting both the occurrence of many different rock types and drastic climatic changes over the last few million years, including ice sheet expansion and decay. The book begins by providing the geological and geomorphological context needed in order to understand this diversity in a relatively small area. In turn, it presents nearly thirty case studies on specific landscapes and landforms, all of which are landmarks in the territory discussed. These include the famous coastal cliffs and landslides, granite tors of Dartmoor, formerly glaciated mountains of Snowdonia and the Lake District, karst of Yorkshire, and many others. The geomorphology of London and the Thames is also included. Providing a unique reference guide to the geomorphology of England and Wales, the book is lavishly illustrated with diagrams, colour maps and photos, and written in an easy-to-read style. The contributing authors are distinguished geomorphologists with extensive experience in research, writing and communicating science to the public. The book will not only be of interest to geoscientists, but will also benefit specialists in landscape research, geoconservation, tourism and environmental protection.

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 book explains to the hillwalker, in easy to understand but accurate terms, how geology has shaped the landscape of Snowdonia. A selection of thirteen guided walks are used to illustrate this in terms of what can be seen on the ground. Divided into two parts, it is intended to help those who love Snowdonia's mountain scenery to understand how this haunting landscape came about. The first half narrates the story of colliding continents, volcanoes, mountain-building and glaciation in creating Snowdonia, explaining why volcanoes occurred, the rocks they created and how to interpret signs of mountain-building and glaciation on the ground. The second half describes several recommended walks, of differing levels of difficulty, but all with a wide variety of geological features to be seen and, most important, enjoying consistently fantastic views of the very best of Snowdonia's wonderful scenery. The author has concentrated on what you can see as you walk around the hills, pointing to conspicuous, easily seen features in rocks and the overall shape of the terrain in accounting for the present day landscape.

In June 1965, a small group of European economic geologists gathered in Heidelberg, Germany, at the invitation of Professor G. C. Amstutz and decided to establish the Society for Geology Applied to Mineral Deposits (SGA) and to start a journal to be called Mineralium Deposita. The first issue of the journal came out in May 1966, and has now matured to a leading journal in economic geology The first Biennial SGA Meeting was held successfully in Nancy, France, in 1991, with subsequent meetings in Grenada (Spain; 1993), Prague (Czech Republic; 1995), Turku (Finland; 1997), London (United Kingdom; 1999), Krakov (Poland; 2001) and Athens (Greece; 2003). In 2002, th the SGA Council decided that its 8 Biennial Meeting in 2005 should be held in Beijing, China, making this the first Biennial Meeting to be convened outside - th rope. Significantly, 2005 also marks the 40 anniversary of the SGA. The decision to host this year’s premier meeting in Beijing reflects the Society’s successful transition from its traditional European focus to a truly global organization, with 24% of SGA members situated in North America, 13% in Australia and Oceania, and 5% in Asia. Over the last 27 years China has made dramatic progress towards political and economic reform, and opening the nation to the outside world. China’s rapid e- nomic development demands increasing amounts of minerals, fuels and materials, and this is currently a major driver for the global economic markets.

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.

Sedimentary Environments is one of the most distinguished and influential textbooks in the earth sciences published in the last 20 years. The first and second editions both won universal praise and became classic works in sedimentology. Since the publication of the last edition, the study of sedimentary environments and facies has made great strides, with major advances in facies modelling, sequence stratigraphy and basin modelling. The 3rd edition of this classic text will likely set the benchmark even higher, and needless to say, will continue being the textbook of choice for sedimentology students. The latest edition of a classic text. Incorporates all the latest advances in dynamic stratigraphy. Will remain the textbook of choice for upper level undergraduate and graduate students in sedimentology.
