Evidence for littoral convergence and sediment delivery to Mattole submarine canyon, Northern California

Autor: Sarah T. Joerger, M. Elliot Smith, Daniel Buscombe, Erich R. Mueller

Publikováno v: Frontiers in Earth Science, Vol 12 (2024)

At geologic timescales, a significant proportion of the sediment eroded from continents is transferred from rivers to littoral cells, then through submarine canyons to deep ocean basins. Accumulation and occasional discharge of sediment from canyon h

Geochemical Evolution of Eocene Lakes in the Nevada Hinterland of the North American Cordillera

Autor: Andrew S. Canada, Elizabeth J. Cassel, M. Elliot Smith

Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 22, Iss 10, Pp n/a-n/a (2021)

Abstract Eocene strata of the Elko Formation record lacustrine deposition within the Nevada hinterland of the North American Cordillera. We present a detailed geochemical stratigraphy enabled by high‐sampling‐resolution geochronology from lacus t

Recurring lacustrine depositional successions in the Wilkins Peak Member, Green River Formation

Autor: Elizabeth Klonowski, Tim Lowenstein, Alan Carroll, M. Elliot Smith, Matteo Paperini, Jeffrey Pietras

Publikováno v: Geosites. 50:1-23

Mineralogy, petrographic textures, and sedimentary structures from the world’s largest trona deposit, the Wilkins Peak Member (WPM) of the early Eocene Green River Formation (GRF), Bridger subbasin, Wyoming, provide key data about depositional cond

Mixed eolian–longshore sediment transport in the late Paleozoic Arizona shelf and Pedregosa basin, U.S.A.: A case study in grain-size analysis of detrital-zircon datasets

Autor: Ryan J. Leary, M. Elliot Smith, Paul Umhoefer

Publikováno v: Journal of Sedimentary Research. 92:676-694

Detrital-zircon U–Pb geochronology has revolutionized sediment provenance studies over the last two decades, and zircon has been successfully analyzed from nearly all sedimentary lithologies, depositional environments, and sediment grain sizes. How

Photogrammetry of sequence and bioherm morphology in the Paradox Formation, Utah, U.S.A.: A test of the coherence of Pennsylvanian (Moscovian) glacio-eustatic sea-level change

Autor: Gary L. Gianniny, M. Elliot Smith, Paul J. Umhoefer, Elizabeth A. Johnson

Publikováno v: Journal of Sedimentary Research. 91:833-846

Despite long-standing recognition of high-amplitude, high-frequency sea-level variation resulting from repeated glaciations of Gondwanaland, recorded as “cyclothems” in late Paleozoic strata worldwide, major questions remain concerning their prec

High-resolution late Paleozoic cyclostratigraphy and tectonic evolution of the Keeler Basin, California, southwest Laurentia

Autor: Patrick J. Gannon, M. Elliot Smith, Ryan J. Leary, Paul J. Umhoefer

Publikováno v: GSA Bulletin. 134:1065-1078

Cyclic strata exposed in the Inyo Mountains of eastern California contain a continuous 6 m.y. record of deep marine deposition that spans the Pennsylvanian–Permian boundary. To better understand the geologic evolution of southwest Laurentia and the

The Permian Monos Formation: Stratigraphic and detrital zircon evidence for Permian Cordilleran arc development along the southwestern margin of Laurentia (northwestern Sonora, Mexico)

Autor: Nancy R. Riggs, Kathleen M. Marsaglia, M. Elliot Smith, Carlos M. González-León, Stephen C. Dobbs, M. Robinson Cecil

Publikováno v: Geosphere. 17:520-537

The southwestern margin of Laurentia transitioned from a left-lateral transform margin to a convergent margin by middle Permian time, which initiated the development of a subduction zone and subsequent Cordilleran arc along western Laurentia. The dis

Estimating the contribution of tributary sand inputs to controlled flood deposits for sandbar restoration using elemental tracers, Colorado River, Grand Canyon National Park, Arizona

Autor: Paul E. Grams, M. Elliot Smith, Rebecca J. Best, Katherine A. Chapman, Erich R. Mueller, Roderic A. Parnell

Publikováno v: GSA Bulletin. 133:1141-1156

Completion of Glen Canyon Dam in 1963 resulted in complete elimination of sediment delivery from the upstream Colorado River basin to Grand Canyon and nearly complete control of spring snowmelt floods responsible for creating channel and bar morpholo
