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.

Download or read book Geology of the Clearwater Mountains and the Southern Boundary of the Alaska Range Suture Zone written by Philip Robert Mooney and published by . This book was released on 2010 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Talkeetna fault is located along the southern margin of the Mesozoic suture zone that juxtaposes an allochthonous island arc, the Wrangellia composite terrane, with the Mesozoic continental margin, the Yukon-Tanana terrane, in south-central Alaska. A discontinuous belt of Mesozoic siliciclastic strata were deposited in the Alaska Range suture zone, an ~150km wide zone of Mesozoic and Cenozoic basins that record the closing of an ocean basin and the collision of exotic terranes. These strata lie along almost the entire length of the margin of the Northern Cordillera, recording the history of the closing of this ocean basin. New geochronologic, structural, and mapping data from the Clearwater Mountains of south-central Alaska demonstrate that the Talkeetna fault is not a major thrust fault, but likely represents a normal fault overprinting a relict, deep-seated, strike slip terrane boundary. LA-ICPMS analysis of zircons from 5 detrital and 2 igneous samples collected from the Clearwater Mountains reveal a unique distribution of age peaks. Four detrital samples from fine-grained strata contain almost exclusively Mesozoic age zircons with single major peaks of ~150 Ma that represent the maximum depositional age of the strata. These strata contain none of the younger zircon signatures commonly found elsewhere in the Alaska Range suture zone. A detrital sample from a structurally unconformable boulder conglomerate juxtaposed against fine-grained siliciclastic strata contains Mesozoic, Paleozoic, and Precambrian grains with a maximum depositional age of ~85 Ma. Zircon ages from igneous rocks within the fine-grained siliciclastic strata, an intrusive gabbro (~142 Ma) and an interlayered volcanic flow (~149 Ma), provide additional constraints on the depositional age of the basin. Collectively, the U-Pb geochronologic data show that the sediments of the Clearwater Mountains were deposited in a location far from the continental margin with material shed from outboard terranes. With no potential sources in the immediate vicinity able to provide detritus of this age to the strata of the Clearwater Mountains, it is clear that these rocks must have been translated along the margin on a strike slip fault.
