The Caledonian highlands of southern New Brunswick are underlain mainly by volcanic, sedimentary, and plutonic rocks of Neoproterozoic age. This report presents results of field mapping, combined with petrologic and geochronological studies, of those Neoproterozoic rocks. It begins with a review of the regional geologic setting, then describes the lithological units. Field and stratigraphic relations among the volcanic and sedimentary rocks in the study area, as well as the distribution, field relations, petrochemistry, and age of the plutonic units, are interpreted. This is followed by interpretation of the tectonic setting and geological history of the area based on rock characteristics and a brief assessment of the area's mineral potential. Appendices include petrographic descriptions and results of geochemical analyses.

"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"--

Special Publication 503 celebrates the career of R. Damian Nance. It features 27 articles, with more than 110 authors based in 18 different countries. These articles include contributions on the processes responsible for the formation and breakup of supercontinents, the controversies concerning the status of Pannotia as a supercontinent, the generation and destruction of Paleozoic oceans, and the development of the Appalachian-Ouachitan-Caledonide-Variscan orogens. In addition to field work, the approaches to gain that understanding include examining the relationships between stratigraphy and structural geology, precise geochronology, geochemical and isotopic fingerprinting, geodynamic modelling, regional syntheses, palaeogeographic modelling, and good old-fashioned arm-waving! The wide range of topics mirrors the breadth and depth of Damian’s contributions, interests and expertise. Like Damian’s papers, the contributions range from the predominantly conceptual to detailed field work, but all are targeted at understanding important tectonic processes. Their scope not only varies in scale from global to regional to local, but also in the range of approaches required to gain that understanding.

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.

Structure and Tectonics of the Indian Continental Crust and Its Adjoining Region: Deep Seismic Studies, Second Edition, collates essential data from seismic studies of Earth's crust across India, offering an essential understanding of the tectonic development of the Indian subcontinent. Seismic studies have been carried out in various parts of India since 1972, recording crust-related seismic data for determination of velocity-depth configuration and determination of structural patterns. The book examines the details of these studies, including their synthesis and global applications. The book presents both background and applications in one cohesive volume for researchers and students of geophysics and geology. - Presents all the information and metadata of the Indian continental crust and its neighbouring regions in a cohesive way - Provides basic knowledge of the Indian subcontinent to support the discussion of seismic studies related to crustal structure - Includes all new chapter covering global applications and synthesis of the findings and observations
