Determining the provenance of Triassic sedimentary rocks in northeastern British Columbia and western Alberta using detrital zircon geochronology, with implications for regional tectonics
Autor: F. Ferri, Michael J. Orchard, Martyn L. Golding, John-Paul Zonneveld, J. K. Mortensen
Publikováno v: Canadian Journal of Earth Sciences. 53:140-155
Triassic rocks of the Western Canada Sedimentary Basin (WCSB) have previously been interpreted as being deposited on the passive margin of North America. Recent detrital zircon provenance studies on equivalent Triassic rocks in the Yukon have suggest

Stratigraphic trends in detrital zircon geochronology of upper Neoproterozoic and Cambrian strata, Osgood Mountains, Nevada, and elsewhere in the Cordilleran miogeocline: Evidence for early Cambrian uplift of the Transcontinental Arch
Autor: Gwen M. Linde, William R. Dickinson, Patricia H. Cashman, James H. Trexler
Publikováno v: Geosphere. 10:1402-1410
U-Pb detrital zircon geochronology provides insight into the provenance of the upper Neoproterozoic–lower Cambrian Osgood Mountain Quartzite and the upper Cambrian–lower Ordovician Preble Formation in the Osgood Mountains of northern Nevada (USA)

Crustal growth and tectonic evolution of the Mojave crustal province: Insights from hafnium isotope systematics in zircons
Autor: Andrew P. Barth, Paul A. Mueller, J. L. Wooden
Publikováno v: Lithosphere. 5:17-28
Coupled U-Pb ages and Hf isotopic ratios in zircons from Proterozoic basement and three siliciclastic cover sequences in southern California provide important insights into the formation of the southern Mojave crustal province and its incorporation i

Continental-scale detrital zircon provenance signatures in Lower Cretaceous strata, western North America
Autor: George E. Gehrels, Andrew Leier
Publikováno v: Geology. 39:399-402
Lower Cretaceous strata and the underlying sub-Cretaceous unconformity in western North America record a profound, but poorly understood change in sedimentation patterns and basin dynamics in the Cordilleran foreland basin. To better understand the r

The Shuram and subsequent Ediacaran carbon isotope excursions from southwest Laurentia, and implications for environmental stability during the metazoan radiation
Autor: Samuel A. Bowring, Brian P. Wernicke, C. Verdel
Publikováno v: Geological Society of America Bulletin. 123:1539-1559
Current understanding of secular changes in the carbon isotopic composition of mid- to late Ediacaran carbonates suggests a relatively long, steady recovery of the global ocean from the Shuram negative excursion, followed by a smaller negative excurs

Chapter 40 The Kingston Peak Formation in the eastern Death Valley region
Autor: Martin J. Kennedy, David Mrofka
Publikováno v: Geological Society, London, Memoirs. 36:449-458
The late Neoproterozoic Kingston Peak Formation (Fm.) is a several-kilometre-thick sedimentary succession primarily influenced by syndepositional tectonism and located in the region around Death Valley, California (Fig. 40.1). Its distribution is div
