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.

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 excerpt: "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"--

Download or read book Geology of the Appalachian Caledonian Orogen in Canada and Greenland written by Harold Williams and published by Geological Society of America. This book was released on 1995 with total page 951 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the Canadian Appalachian region. The chapter on the East Greenland Caledonides stands alone and there is no attempt to integrate the geological accounts of the two far removed regions. Rocks of the Canadian Appalachian region are described under four broad temporal divisions: lower Paleozoic and older, middle Paleozoic, upper Paleozoic, and Mesozoic. The rocks of these temporal divisions define geographic zones, belts, basins, and graben, respectively. The area is of special interest because so many modern concepts of mountain building are based on Appalachian rocks & structures.
Download or read book The Nature of Magmatism in the Appalachian Orogen written by A. Krishna Sinha and published by Geological Society of America. 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. 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
