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. The vast store of new information.
