This book represents the third in the series on the Precambrian and Palaeozoic geolo- gy of Circum-Atlantic regions developed under the IGCP (International Geological Correlation Programme) Project # 233 on Terranes in the Circum-Atlantic Palaeo- zoic Orogens. The book is an up-to-date and comprehensive account of the Pre- Mesozoic Geology of France (Armorican and Central Massifs) and related areas (Aquitaine Basin, Vosges, Crystalline Provence, Pyrenees, western Alps, Corsica and Sardinia) that systematically reviews the geophysics, stratigraphy, palaeontology, structure, metamorphism, igneous activity and metallogeny. The need for such a book became apparent at the international copference held in Montpellier, France, in Au- gust, 1988, where a vast amount of new information was presented. The collection of papers presented at the conference and published in Tectonophysics, however, does not give the comprehensive treatment of the geology required for terrane analysis that is provided by this book. We sincerely appreciate the work ofthe reviewers whose comments have helped to ensure that this book has an international appeal. We also thank the authors whose diligent efforts have provided an excellent synthesis. Halifax, Nova Scotia, Canada 1993 J.
