Simultaneous Middle Pleistocene eruption of three widespread tholeiitic basalts in northern California (USA): Insights into crustal magma transport in an actively extending back arc

Autor: Robert L. Christiansen, Michael A. Clynne, L. J. Patrick Muffler, D. T. Downs, Andrew T. Calvert, Duane E. Champion

Publikováno v: Geology. 48:1216-1220

Mapping and chronology are central to understanding spatiotemporal volcanic trends in diverse tectonic settings. The Cascades back arc in northern California (USA) hosts abundant lava flows and normal faults, but tholeiitic basalts older than 200 ka

The remarkable volcanism of Shastina, a stratocone segment of Mount Shasta, California

Autor: C.A. Gardner, Robert L. Christiansen, Andrew T. Calvert, Jorge A. Vazquez, Duane E. Champion, Judith Fierstein

Publikováno v: Geosphere. 16:1153-1178

Mount Shasta, a 400 km3 volcano in northern California (United States), is the most voluminous stratocone of the Cascade arc. Most Mount Shasta lavas vented at or near the present summit; relatively smaller volumes erupted from scattered vents on the

Tectonomagmatic evolution of Cenozoic extension in the North American Cordillera

Autor: Brian P. Wernicke, Philip England, Leslie J. Sonder, Robert L. Christiansen

The spatial and temporal distributions of Cenozoic extension and magmatism in the Cordillera suggest that the onset of major crustal extension at a particular latitude was confined to a relatively narrow belt (

The Yellowstone 'hot spot' track results from migrating basin-range extension

Autor: Don L. Anderson, Gillian R. Foulger, Robert L. Christiansen

Whether the volcanism of the Columbia River Plateau, eastern Snake River Plain, and Yellowstone (western U.S.) is related to a mantle plume or to plate tectonic processes is a long-standing controversy. There are many geological mismatches with the b

What makes hydromagmatic eruptions violent? Some insights from the Keanakāko'i Ash, Kı̄lauea Volcano, Hawai'i

Autor: Carl R. Thornber, Melvin H. Beeson, Larry G. Mastin, Jacob B. Lowenstern, Robert L. Christiansen

Publikováno v: Journal of Volcanology and Geothermal Research. 137:15-31

Volcanic eruptions at the summit of Kilauea volcano, Hawai'i, are of two dramatically contrasting types: (1) benign lava flows and lava fountains; and (2) violent, mostly prehistoric eruptions that dispersed tephra over hundreds of square kilometers.
