      The book contains 45 extensively illustrated articles. It starts with papers on the Mesozoic source rocks, and oceanic natural gas clatrates in the Arctic, respectively. Then follow articles on the regional and petroleum geology of the main regions; Greenland, North American Arctic, Soviet Arctic and the Barents Sea. Particular emphasis is. @article{osti_, title = {Evolution of the Arctic-North Atlantic and western Tethys}, author = {}, abstractNote = {A broad, multi-disciplinary overview of the late Paleozoic to recent geological evolution of much of northeastern North America, Greenland, all of Europe, and the northern parts of North Africa.

Most Quaternary sediments in North America north of 45 ON post-date the last deglaciation. This volume looks at those extensive deposits from the standpoints of timing, cause, and mechanism of the wastage of North American ice during the last deglaciation and the accompanying environmental changes in the nonglaciated and deglaciated areas.

oceanic regions and the surrounding continental margins: Nairn et al. () and Grantz et al. (), with the latter including reviews of the history of investigation and of the resources. The 27th IGC published a report on arctic geology (Gramberg et al.

The last Arctic Cited by:   The vast Arctic region contains nine proven petroleum provinces with giant resources but over half of the sedimentary basins are completely undrilled, making the region the last major frontier for conventional oil and gas exploration.

This book provides a comprehensive overview of the geology and the petroleum potential of the Arctic. Similarly, warm ocean conditions in Cambrian to Devonian time produced widespread carbonate platforms over the St. Lawrence Lowlands, the Western Interior, Mackenzie Corridor, Hudson Bay and the southern Arctic.

Events of the Mesozoic are prominently represented by the accretion of continental fragments to the western margin of North America. Arctic - Arctic - Greenland: Erik the Red founded a small Norse colony on Greenland in adalthough the Norse and the Thule people seem not to have interacted until the 13th century.

The Norse colony was abandoned in the early 15th century, a time when a general climatic cooling trend probably made subsistence farming unsustainable there. Physical geography. North America—the continent and associated islands of the Northern Hemisphere and (chiefly) Western Hemisphere.

It lies northwest of South America and is bounded by the Atlantic, Arctic, and Pacific Oceans. Middle America—the territory between the southern Rocky Mountains and the northern tip of the isthmus marks the transition between North and South America.

Arctic - Arctic - Terrain: Although the detail of the terrain in many parts of the Arctic is directly attributable to the Pleistocene glaciations, the major physiographic divisions reveal close correlation with geologic structure. The two largest shield areas, the Canadian and the Baltic, have developed similar landscapes.

West of Hudson Bay, in southwestern Baffin Island, and in Karelia the. The Arctic Ocean is the smallest and shallowest of the world's five major oceans It is also known as the coldest of all the oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic is sometimes classified as an estuary of the Atlantic Ocean, and it is also seen as the northernmost part of the all-encompassing.

The North Pole is the northernmost point on Earth. It is the precise point of the intersection of the Earth's axis and the Earth's surface.

From the North Pole, all directions are south. Its latitude is 90 degrees north, and all lines of longitude meet there (as well as at the South Pole, on the opposite end of the Earth). Polaris, the current North Star, sits almost motionless in the sky.

J., Ed. Welcome to the website of Arctic Geology. “Arctic Geology” is a thematic network within the University of the Arctic. It is a research and educational collaboration between different universities from Arctic countries (Norway, Sweden, Finland, Russia, Iceland, Greenland and Canada) focusing mainly on minerals and hydrocarbure ressources in the Arctic.

The Arctic Ocean seafloor is divided by three large mountain ranges that run parallel between Siberia and Greenland: the Nansen-Gakkel Ridge, which runs across the northern basin of western Russia to Greenland; Lomonosov Ridge, which sits on average ab ft high above the abyssal plain; and the Alpha Ridge.

Encyclopedia of Geology, Second Edition presents state-of-the-art reviews on the various aspects of geologic research, all of which have moved on considerably since the writing of the first edition. New areas of discussion include extinctions, origins of life, plate tectonics and its influence on faunal provinces, new types of mineral and hydrocarbon deposits, new methods of dating rocks, and.

The contiguous United States (the 'Lower 48') are divided into physiographic provinces according to their geomorphology. Geomorphology refers to the physical features and processes of landforms, and their relation to geologic structures.

The climate, underlying geology, and the geologic history of an area affect the modern topography. The Arctic region of our planet consists of a deep, largely ice-covered ocean surrounded by the land masses of Eurasia and North-America.

The physical geography of the region encompasses the moun-tainous regions of Alaska, the ice masses of Greenland and Arctic Canada and the flat plains and tundras of Siberia.

Greenland, the world's largest island, is a high plateau covered by a vast ice sheet except in the coastal regions; smaller ice caps are found on other Arctic islands.

Because ice is a significant component of arctic lands and shores, sometimes alone and sometimes as a component of frozen soils, coastal erosion due to global warming is much. Previous compilations on Arctic geology Symposia dedicated to charting the state of knowledge of Arctic geology, especially from the point of view of petroleum, were held in North America at.

Physiography The Arctic may briefly be described as a per- ennially ice-covered, deep ocean, surrounded by islands, continental coastal areas, and of peri- pheral, seasonally ice-covered seas. The land- masses mostly consist of lowland. High moun- tain ranges are found only in Alaska, eastern- most Siberia and Canada, and in Greenland.
