Synopsis Proterozoic Crustal Evolution by : K.C. Condie
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.

Synopsis Dyke Swarms - Time Markers of Crustal Evolution by : E. Hanski
Dyke swarms are remnants of large igneous provinces, and are pointers of continental break-up events, as well as indicators for ancient continental reconstructions. These global geodynamic aspects are of crucial significance in tectonics, and with recent developments in high-precision age, dating it has become possible to enter these short-lived ma

Synopsis Precambrian Geology of Finland by : Martti Lehtinen
Focusing on the Precambrian in the central part of the Fennoscandian Shield, the book combines the results from modern geological and geophysical research into a detailed petrologic, lithologic, and structural synthesis and interpretation of the Archean and Proterozoic of Finland. It will be of value to anyone interested in the evolution of the shield in particular and in Precambrian geology in general.

Synopsis The Deep Proterozoic Crust in the North Atlantic Provinces by : Alex C. Tobi
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".

Synopsis Proterozoic East Gondwana by : Masaru Yoshida
This volume focuses on Late Mesoproterozoic to early Cambrian events related to Gondwana assembly and break up. The nineteen papers provide a comprehensive review including advanced knowledge and new data from all critical areas of East Gondwana. The recent knowledge of the evolution of East Gondwana, which was regarded as an integral part of the Mesoproterozoic supercontinent Rodinia, is the major theme of the volume, which is reinforced by highlighting this radical and new understanding of the evolution of this region.
