Download or read book Yukon written by Melody Webb and published by UBC Press. This book was released on 1993 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering vast distances in time and space, Yukon: The Last Frontier begins with the early Russian fur trade on the Aleutian Islands and closes with what Melody Webb calls 'the technological frontier'. Colourful and impeccably researched, her history of the Yukon Basin of Canada and Alaska shows how much and how little has changed there in the last two centuries. Successive waves of traders, trappers, miners, explorers, soldiers, missionaries, settlers, steamboat pilots, road builders, and aviators have come to the Yukon, bringing economic and social changes, but the immense land 'remains virtually untouched by permanent intrusions.'

Download or read book Tectonic Growth of a Collisional Continental Margin written by Kenneth D. Ridgway and published by Geological Society of America. This book was released on 2007 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The convergent margin of southern Alaska is considered one of the type areas for understanding the growth of continental margins through collisional tectonic processes. Collisional processes that formed this margin were responsible for multiple episodes of sedimentary basin development, subduction complex growth, magmatism, and deformation. Two main collisional episodes shaped this Mesozoic-Cenozoic continental margin. The first event was the Mesozoic collision of the allochthonous Wrangellia composite terrane. This event represents the largest addition of juvenile crust to western North America in the past 100 m.y. The second event is the ongoing collision of the Yakutat terrane along the southeastern margin of Alaska. This Cenozoic event has produced the highest coast mountain range on Earth (Saint Elias Mountains), the Wrangell continental arc, and sedimentary basins throughout southern Alaska. Active collisional processes continue to shape the southern margin of Alaska, mainly through crustal shortening and strike-slip deformation, large-magnitude earthquakes, and rapid uplift and exhumation of mountain belts and high sedimentation rates in adjacent sedimentary basins. This volume contains 24 articles that integrate new geophysical and geologic data, including many field-based studies, to better link the sedimentary, structural, geochemical, and magmatic processes that are important for understanding the development of collisional continental margins."--Publisher's website.
