The Geology of Continental Margins


Book Description

The continental margins of the world constitute the most impressive and largest physiographic feature of the earth's surface, and one of fundamentally great geological significance. Continental margins have been the subject of increasing attention in recent years, an interest focused by a body of new data that has provided new insights into their character. This interest was further stimulated by the realization that, in addition to the abundant living resources, continental margins contain petroleum and mineral resources that are accessible with existing technology. This realization, along with their basic geological importance, has provoked further research into the nature of continental margins throughout the world. A summary of these findings, as related to both recent and ancient continental margins, is the subject of this book. At various times in the past we had been approached individually to prepare a basic reference to continental margins; we then proposed to do such a volume jointly. However, the stimulus for the present volume eventually arose from a Penrose Conference arranged through the Geological Society of America. This conference was attended by specialists of numerous disciplines and from throughout the world, many of whom insisted that such a volume would be both timely and useful. Consequently, we agreed to undertake the task of assembling this book, with the objectives of making it available as soon and as inexpensively as possible.




Geology of the Continental Margin of Eastern Canada


Book Description

The continental margin of eastern Canada extends from Georges Bank at 41 degrees North to Nares Strait at 80 degrees North, almost half the distance from the Pole the equator. It is a classical example of a passive or 'Atlantic" type of continental margin with a geological history reflecting at least two 'Wilson Cycles". The first gave birth to the Iapetus Ocean, and the second to the modern Atlantic and its neighbors. The margin ties the glacial history of the Canadian landmass to the adjacent ocean basins, and so to the world's oceans. Two of the basins offshore eastern Canada, the Jeanne d'Arc Basin off Newfoundland and the Scotian Basin off Nova Scotia, contain substantial resources of oil and gas. An understanding of the geology of the margin bears directly on the evolution of the whole of the North Atlantic and the Arctic, and on the generation of hydrocarbons.







The Sedimentary Basins of the United States and Canada


Book Description

The Sedimentary Basins of the United States and Canada, Second Edition, focuses on the large, regional, sedimentary accumulations in Canada and the United States. Each chapter provides a succinct summary of the tectonic setting and structural and paleogeographic evolution of the basin it covers, with details on structure and stratigraphy. The book features four new chapters that cover the sedimentary basins of Alaska and the Canadian Arctic. In addition to sedimentary geologists, this updated reference is relevant for basin analysis, regional geology, stratigraphy, and for those working in the hydrocarbon exploration industry. - Features updates to existing chapters, along with new chapters on sedimentary basins in Alaska and Arctic Canada - Includes nearly 300 detailed, full-color paleogeographic maps - Written for general geological audiences and individuals working in the resources sector, particularly those in the fossil fuel industry

Non-volcanic Rifting of Continental Margins


Book Description

Non-continental margins lack thick lavas that are generated as continental crust thins immediately prior to the onset of seafloor spreading. They may form up to 30 per cent of passive margins around the world. This volume contains papers examining an active margin, fossil margins that border present day oceans, and remnants of margins exposed today in the Alps. The papers present evidence across a range of scales, from individual mineral grains, through borelide cores and outcrop, to whole margins at the crustal scale.




Regional Geology and Tectonics: Phanerozoic Passive Margins, Cratonic Basins and Global Tectonic Maps


Book Description

Expert petroleum geologists David Roberts and Albert Bally bring you Regional Geology and Tectonics: Principles of Geologic Analysis, volume one in a three-volume series covering Phanerozoic regional geology and tectonics. It has been written to provide you with a detailed overview of geologic rift systems, passive margins, and cratonic basins, it features the basic principles necessary to grasping the conceptual approaches to hydrocarbon exploration in a broad range of geological settings globally. A "how-to" regional geology primer that provides a detailed overview of tectonics, rift systems.




Geology of the Appalachian—Caledonian Orogen in Canada and Greenland


Book Description

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.
