Opis

This volume puts the Geological Conservation Review sites of south west England into their geological context. Details are given of the lavas, granites and associated rocks of Devon and Cornwall, which were formed throughout a major mountain-building episode, between 450-270 million years ago, and have shaped the economic growth of the region.

Recenzje

The authors have done an excellent job of describing the sites and explaining their significance. They provide an up-to-date bibliography for the specialist reader and a glossary for the non-specialist. This volume is beautifully produced and very well illustrated... This review will be of lasting value and many geologists who know the region will want to own a copy... - Mineralogical Magazine; Detailed description of the sites is straightforward and didactically presented: high-lights, introduction, description, interpretation and conclusion. This scheme, followed throughout the book, is an excellent and useful idea...straightforward and clear explanations of sites and geologic problems presented make this book an excellent companion for field use - Lithos; a detailed listing of the most 'significant' igneous localities in Devon and Cornwall...excellently presented...of the highest quality. Serious libraries of geology will want copies - Geological Magazine; provides a wealth of geological data in an easily accessible format...highly readable accounts of the geology at a locality and regional level which would act as a starting point for deeper research...I would strongly recommend that all tertiary teaching institutions in Great Britain with a geology course consider purchase of the volume for their libraries - Lithos; this volume constitutes a good background for all the visitors of the south-west England who desire a general view of the Hercynian history of this area or to prepare a geological field-trip in this region - Earth-Science Reviews
