Geology Of Northeast Ellesmere Island Adjacent To Kane Basin And Kennedy Channel Nunavut

The 5-year Circum-Arctic Lithosphere Evolution (CALE) program developed new constraints on the tectonic history of the central Amerasia basin of the Arctic Ocean. This volume is the final synthesis of the CALE program, which brought together an international team of scientists to develop integrated, multi-disciplinary understanding of the region. This approach, based on the integration of much new geological and geophysical data from onshore and offshore , is necessary to advance our understanding of this basin. Regional onshore-to-offshore transects are central to the 18 papers in this volume. The diverse science supporting these crust-to-mantle regional transects includes structural, geochronological, isotopic, potential fields, and seismic reflection and refraction data. Four chapters present circum-Arctic investigations by the regional CALE teams. The final chapter addresses pan-Arctic themes. This unique collaboration, relying on new data and new syntheses of existing data sheds new light on the history of the Arctic Ocean.

"To recognize the 25th anniversary of the Circum-Arctic Structural Events program, an effort organized by the Bundesanstalt für Geowissenschaften und Rohstoffe, this volume presents results from 18 major field expeditions involving 100+ geoscientists from a spectrum of disciplines. The volume focuses on the Proterozoic to Cenozoic tectonic evolution of the circum-Arctic region with correlations to adjacent orogens"--

"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"--

The Ordovician was one of the longest of the geological periods, characterized by major magmatic and tectonic activity, an immense biodiversification, swings in climate and sea levels, and the first Phanerozoic mass extinction. ‘A Global Synthesis of the Ordovician System’ is presented in two volumes in The Geological Society, Special Publications. Whereas the first volume (SP532) concentrates on general aspects and a synthesis of the Ordovician geology of Europe, this volume (SP533) includes reviews of Ordovician successions of most other parts of the world. The classic successions of the Ordovician basins of North America are presented, as well as those of China where several of the Ordovician Global Boundary Stratotype Sections and Points are defined. The volume also includes syntheses of the Ordovician geology of Africa, South America, most regions of Asia from the Near to the Far East along with Central Asia, as well as Australia, New Zealand and Antarctica.
