Download or read book Uppermost Proterozoic Formations in Central Mackenzie Mountains Northwest Territories written by James D. Aitken and published by Geological Survey of Canada. This book was released on 1989 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This bulletin provides a full description of the characteristics and stratigraphic relationships of the Sheepbed and younger formations of the central Mackenzie Mountains, and establishes new nomenclature for the Proterozoic post-Sheepbed formations. The earliest occurrences of fossils are placed in a clear relationship both to the youngest of the Proterozoic glacigenic deposits and the oldest Cambrian strata of the region. Four definitions of formations are proposed (Gametrail, Blueflower, Risky, and Ingta formations), with information on origin of name, type & reference sections, boundaries, dimensions, age, correlation, and origin.

Available in PDF, EPUB and Kindle. Book excerpt: The early chapters of the volume present data and interpretations of the geophysics of the craton and summarise, with sequential maps, the tectonic evolution of the craton. The main body of the text and accompanying plates and figures present the stratigraphy, structural history, and economic geology of specific sedimentary basins and regions. The volume concludes with a summary chapter in which the currently popular theories of cratonal tectonics are discussed and the unresolved questions are identified.

Book excerpt: "This Memoir focuses on 7 'turning points' that had specific and lasting impacts on Laurentian evolution: The Neoarchean, characterized by cratonization; the Paleoproterozoic and the initial assembly of Laurentia; the Mesoproterozoic southern margin of Laurentia; the Midcontinent rift and the Grenville orogeny; (5) the Neoproterozoic breakup of Rodinia; the mid-Paleozoic phases of the Appalachian-Caledonian orogen; and the Jurassic-Paleogene assembly of the North American Cordillerar"--

Download or read book Late Proterozoic and Cambrian Tectonics Sedimentation and Record of Metazoan Radiation in the Western United States written by Nickolas Christie-Blick and published by American Geophysical Union. This book was released on 1989 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Field Trip Guidebooks Series, Volume 331. The articles and guide which follows them have been prepared for an eight-day field excursion organized in conjunction with the 28th International Geological Congress in Washington, D.C., in July, 1989. The purpose of the excursion is to review the results of recent research concerning the tectonic, stratigraphic and sedimentological development of the western United States in Late Proterozoic and Cambrian time, and the paleoenvironmental context of the latest Proterozoic and Early Cambrian metazoan radiation event. The location and tectonic setting of stops are shown in the Frontispiece. Our studies build on those of many other geologists, whose contributions are acknowledged in the list of references. In particular, we draw attention to the fundamental contributions over many years of C.A. Nelson, J.H. Stewart and L.A. Wright, and the late M.D. Crittenden, Jr. and S.S. Oriel. Without the basic observations and insights of these individuals, it is unlikely that the present level of understanding would have been achieved. At the same time, we recognize that interpretations and ideas summarized here are subject to revision as research continues.

This book was released on 2000 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The area described in this report is located in the area of the Selwyn Valley, between the Selwyn and Mackenzie mountains on the Yukon-Northwest Territories border. The main section details the stratigraphy of the area and describes 27 mappable units, from the Upper Proterozoic to Carboniferous & recent volcanics, in four different facies zones, including ten new formations. This is followed by description of the area's three main structural domains, plus brief descriptions of intrusive rocks and regional metamorphism. The final section describes mineral occurrences and assesses the potential for economic deposits. The appendix contains paleontological identifications of specimens collected.
