This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Geological mapping combined with U-Pb (zircon) dating and petrological work have resulted in revised interpretations of Neoproterozoic plutonic rocks in the southern Cobequid Highlands. The Frog Lake, Debert River, and McCallum Settlement plutons, as well as the western part of the Gain Brook pluton, consist of the same three components in varying proportions: dioritic rocks, tonalitic to granodioritic rocks, and granitic rocks ranging from monzogranite to alkali-feldspar granite. Based on petrographic and chemical characteristics, the dioritic rocks are comagmatic low-potassium tholeiite suite showing Fe- and Ti-enrichment trends. The tonalitic, granodioritic, and granitic rocks display similar chemical trends and constitute a comagmatic calc-alkalic suite. Both the tholeiitic dioritic rocks and the calc-alkalic intermediate to felsic rocks formed in a volcanic-arc setting, but lack of chemical continuity between them indicates that they are not comagmatic. However, mingled relationships and previously published and new U-Pb (zircon) ages indicate that they are the same age and likely formed in the roots of the same volcanic arc at ca. 615-605 Ma. Hence it is suggested that they be collectively renamed the Bass River plutonic suite. In contrast, the Gunshot Brook pluton in the eastern Cobequid Highlands, although apparently of similar age, displays petrological differences and is not included in the suite. The older Economy River Orthogneiss is chemically distinct and likely part of the previously identified ca. 750-730 Ma Mount Ephraim Plutonic Suite. The Bass River plutonic suite is similar in age and chemical character to some plutons in the northern Cobequid Highlands, Antigonish Highlands, and southeastern New England, and these areas may have been originally together, forming a distinctive part of West Avalonia.
Book Synopsis Field Relations, Petrology, and Structure of Neoproterozoic Rocks in the Caledonian Highlands, Southern New Brunswick by : S. M. Barr
Download or read book Field Relations, Petrology, and Structure of Neoproterozoic Rocks in the Caledonian Highlands, Southern New Brunswick written by S. M. Barr and published by . This book was released on 1999 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Pannotia to Pangaea written by B. Murphy and published by Geological Society of London. This book was released on 2021-01-28 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis From Rodinia to Pangea by : Richard P. Tollo
Download or read book From Rodinia to Pangea written by Richard P. Tollo and published by Geological Society of America. This book was released on 2010 with total page 972 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

This book was released on 1997-01-01 with total page 892 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Stratigraphy, Tectonic Setting, and Geological History of Late Precambrian Volcanic-sedimentary-plutonic Belts in Southeastern Cape Breton Island, Nova Scotia by : Sandra M. Barr
Download or read book Stratigraphy, Tectonic Setting, and Geological History of Late Precambrian Volcanic-sedimentary-plutonic Belts in Southeastern Cape Breton Island, Nova Scotia written by Sandra M. Barr and published by . This book was released on 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This bulletin is the result of a systematic remapping of the Late Precambrian volcanic, sedimentary, and plutonic rocks of south-eastern Cape Breton Island, last mapped in the 1940s. The investigative work included precise uranium-lead dating from key units throughout the study area, showing the differences in ages in the volcanic and sedimentary rocks previously lumped together as a single unit. These rocks have been divided into three groups based on ages, and each group has been subdivided into lithofacies units. Petrological/geochemical data are used in combination with field observations to interpret the tectonic setting and geological evolution of the study area. Major units described in the bulletin include the Stirling belt, the East Bay Hills belt, the Coxheath Hills belt, the Sporting Mountain belt, the coastal belt, and Upper Precambrian to Lower Palaeozoic units.
