The Betts Cove area of the Baie Verte Peninsula, northern Newfoundland, is of interest for its mineral exploration history and for its ophiolitic complex formed through sea floor spreading. This study attempts to resolve some of the unresolved problems related to the area's stratigraphy, the magmatic affinity of its plutonic section, and the geologic controls on ore deposition. The report presents a revised stratigraphy for the area; a petrologic description of the rock units of the Betts Cove ophiolite, Snooks Arm Group, adjoining ophiolitic rocks, and post-Ordovician rocks; a history of structural deformation in the area; information on mineral chemistry, geochemistry, and petrogenesis; and tectonic models illustrating the evolution of the ophiolite and its cover rocks. The final section describes mineral deposits & occurrences in the area, including historic volcanogenic copper/sulphide mines, the currently producing Nugget Pond mine, and various gold occurrences.

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.

This volume focuses on the Canadian Appalachian region. The chapter on the East Greenland Caledonides stands alone and there is no attempt to integrate the geological accounts of the two far removed regions. Rocks of the Canadian Appalachian region are described under four broad temporal divisions: lower Paleozoic and older, middle Paleozoic, upper Paleozoic, and Mesozoic. The rocks of these temporal divisions define geographic zones, belts, basins, and graben, respectively. The area is of special interest because so many modern concepts of mountain building are based on Appalachian rocks & structures.
