Available in PDF, EPUB and Kindle. Book excerpt: As a final product of the International Geological Correlation Program (IGCP) Project 217, this volume brings together significant advances in the understanding of Proterozoic crustal evolution. This IGCP Project focussed on nine research objectives: 1) Comparison of Archean and Proterozoic supracrustal assemblages to more fully understand differences between Archean and post-Archean tectonic regimes; 2) To more fully understand the geochemical differences between Archean and post-Archean sediments and to evaluate the various factors that control sediment composition; 3) From combined U/Pb zircon and whole-rock Sm/Nd studies, to see if the apparent 2.4-2.0 continental crust "generation gap" is real; 4) To employ new techniques in the dating of individual zircons to more fully understand Proterozoic tectonic history and the role of crustal reworking; 5) From trace element ratios and Nd isotopic data from basalts, to better understand Proterozoic mantle evolution; 6) To encourage more detailed studies of the anorogenic granite-anorthosite association to better understand its origin and significance in terms of crustal evolution; 7) From combined Nd, Pb, and Sr isotopic data, to more precisely estimate the amount of new continental crust formed during the Proterozoic; 8) To encourage joint P-T and geochronological studies of Proterozoic and high-grade terranes to better understand Proterozoic orogenesis: and 9) To try and understand why hydrothermal precious metal deposits are relatively rare in the Proterozoic compared to both the Archean and the Phanerozoic. The book should be of interest to professionals in the geosciences (especially geochemists, petrologists and structural geologists) and graduate students in the same fields.

Book excerpt: Later Proterozoic Stratigraphy of the Northern Atlantic stimulating and their prompt submission of text and illustrative material has enabled rapid production of Regions aims to produce a concise and up-to-date synthesis of the later Proterozoic geology of those lands the book. Funding for this research has come from many bordering the North Atlantic that were once situated sources, including the Natural Environment Research north of the Iapetus Suture and the Tornquist Line. Council, the British Geological Survey, the Geological Proterozoic rocks deposited between 1150 and 650 Ma Surveys of Greenland and Newfoundland and many (the latter date marked by the Varanger glaciation) are universities. the main subject of the book, although reference is also Many of the chapters use differing and interesting made to deposits laid down at the end of the Proterozoic methods of approach, including structural analysis, in Scandinavia, Newfoundland and Greenland. The sedimentology, whole-rock trace element geochemistry, need for such a comprehensive review has become geophysics, and isotopic age dating. The scope of the increasingly apparent in recent years, because the original research was extended to include formerly introduction of many new methods of resolving pro adjacent areas and, as a result, a number of useful blems in complex metamorphic terrains has unlocked a correlations between these regions can be made.

This book was released on 2012-12-06 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Proterozoic terrains of South Scandinavia and the Grenville Province in North-America have many common features : Regional high grade metamorphism (Granulite-facies), anorthosites, etc. They are separated by the Caledonian orogeny and, above all, by the Atlantic Ocean. During the time of the great continental drift controversy, few people were ready to admit that both sides on the Atlantic were once an unique province. Now everybody agrees on the Post-paleozoic age of the Atlantic and, consequently, on the intrinsic homogeneity of the much older. rocks which occur around it. But a detailed comparison is not easy. The Grenville Province is much larger than South Scandinavia, both regions have been investigated by a great number of different schools, using various methods, approaches and concepts. After several attempts, and long discussion, it was felt by a small group of individuals, that literature study would not be enough and that nothing could re place the direct contact, in the field, of specialists who had a first hand knowledge of all involved regions. The formula of a NATO Advanced Study Institute, which gives a unique opportunity to meet and mix people of various origin and levels, came almost by itself. Much work was needed, much help has been obtained, as detailed in the "Acknowledgements".

Book excerpt: This book provides a synthesis of Archaean and Proterozoic crustal evolution in the North Atlantic Region. There is particular reference to Proterozoic collisional tectonics.
