The thermal evolution of mountain belts is recorded inthe distribution, origin and ages of magnatism. In this volume, petrologic, isotopic and geochemical evidence is presented to highlight the contribution of igneous rocks to the evolution of the Appalachian Orogen in both Canada and the United States. These papers emphasize the use of modern geochemical and petrologic data to discriminate the sources yielding magmas, and thus the nature of the crust and mantle.

"This volume provides a comprehensive overview of our understanding of the evolution of the Appalachian-Caledonian-Variscan orogen. It takes the reader along a clockwise path around the North Atlantic Ocean from the U.S. and Canadian Appalachians; to the Caledonides of Spitsbergen, Scandinavia, Scotland and Ireland; and thence south to the Variscides of Morocco"--

"The Appalachians constitute one of Earth's major tectonic features and have served as a springboard for innovative geologic thought for more than 170 years. This volume contains 36 original papers reporting the results of research performed throughout nearly the entire length and breadth of the Appalachian region, including all major provinces and geographical areas. Memoir 206 was designed to commemorate the (near-)fortieth anniversary of the publication of the classic Studies of Appalachian Geology volumes that appeared just prior to the application of plate tectonic concepts to the region. Contributions concerning structural evolution, sedimentation, stratigraphy, magmatic processes, metamorphism, tectonics, and terrane accretion illustrate the wide range of ongoing research in the area and collectively serve to mark the considerable progress in scientific thought that has occurred during the past four decades."--pub. desc.

The 19 original papers on the tectonic evolution of mountain systems were collected to mark the 50th anniversary of Price's description of the Canadian Cordillera. A sampling of topics turns up the driving mechanism and three-dimensional circulation of plate tectonics, the Belt-Purcell Basic as the keystone of the Rocky Mountain fold-and-thrust belt in the US and Canada, Silurian-Devonian orogenic events in the central Appalachians and the crystalline southern Appalachians, and defining the eastern boundary of the North Asian craton from structural and subsidence history studies of the Verkhoyansk fold-and-thrust belt. A fold-out sheet of color maps and diagrams is tucked into a pocket inside the back cover.

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.
