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.

Regional Studies is a collection of papers that deals with strata-bound mineral deposits in the Eastern Alps, in the Canadian Cordillera, in north-central, and southwest England. Other papers describe southern African stratiform ore deposits and the genesis of Irish base-metal deposits. One paper compares the various types of volcanogenic mineral deposits and their depositional environments characterized by distinct assemblages of volcanic rocks, which formed in the Northern Appalachians during certain episodes of the tectonic evolution. The paper notes that the youngest volcanogenic deposits of economic interest are tungsten—molybdenum—tin—bismuth base metal deposits in highly altered rhyolitic sub-volcanic complexes at Mount Pleasant, New Brunswick. Another paper reviews the mineral occurrences in southern Africa that include stratiform, non-magmatic, ore deposits, The paper considers a subdivision of deposits formed from surficial chemical processes during previous (or current) cycles of weathering and erosion. Many ore bodies have a dual origin: for example, the iron in the high-grade hematite deposits is partly syngenetic and partly epigenetic. The paper also illustrates the time-dependence of some stratiform ore deposits in southern Africa in a schematic diagram. Geologists, researchers, or engineers whose works are related with ore deposits and mining will benefit tremendously from the collection.

This edited work contains the most recent advances related to the study of layered intrusions and cumulate rocks formation. The first part of this book presents reviews and new views of processes producing the textural, mineralogical and geochemical characteristics of layered igneous rocks. The second part summarizes progress in the study of selected layered intrusions and their ore deposits from different parts of the world including Canada, Southwest China, Greenland and South Africa. Thirty experts have contributed to this update on recent research on Layered Intrusions. This highly informative book will provide insight for researchers with an interest in geology, igneous petrology, geochemistry and mineral resources.

"In Sight of the Suture is the first overview of the pre-Carboniferous geology of the Isle of Man since the 1960s. It will be of prime interest to research workers in the geology of the Caledonian/Appalachian orogenic belt, to sedimentologists interested in deep marine processes and to petroleum geologists focusing on exploration in the Irish Sea."--BOOK JACKET.
