Book Description
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.

Book Description
"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.

Book Description
Consisting of papers that have appeared recently in International Geology Review, Middle American Terranes, Potential Correlatives, and Orogenic Processes focuses on Middle American terranes in which tectonic processes, including flat-slab subduction, for orogenic development are examined at various times since the late Mesoproterozoi

Book Description
"This book includes petrology, geochronology, and regional aspects of individual plutons, as well as evolution of the Peninsular Ranges batholith. Several chapters deal with geophysical, chemical, and isotopic based interpretations of the genesis and evolution of the batholith. An accompanying DVD contains detailed colored maps and chemical, isotopic, mineralogic, and physical properties data"--Provided by publisher.

Book Description
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.
