Geochemical expression of volcanism in an on-axis and intraplate hotspot : Cobb and Marquesas

Creator:

Desonie, Dana L.

Abstract:

The Pacific Ocean basin is home to a set of hotspots diverse in their eruption rate, duration of volcanism, and basalt chemistry. Pacific hotspots are found in a spectrum of distinct plate tectonic settings, from near a spreading ridge to intraplate. Cobb hotspot, which resulted in formation of the Cobb-Eickelberg...

Diffuse deformation patterns along the North American plate boundary zone, offshore western United States

Creator:

Chaytor, Jason D.

Abstract:

Plate boundaries are commonly regions of complex, diffuse deformation with the motion across the boundary accommodated by numerous structural systems, rather than being narrow, discrete zones of deformation. One such boundary occurs where the North American plate makes contact with Juan de Fuca, Gorda, and Pacific plates along the west...

The petrology, geochemistry, and geochronology of hotspot seamounts in the North Pacific and arc/backarc volcanism on the northern Antarctic Peninsula

Creator:

Keller, Randall A.

Abstract:

Volcanic rocks from hotspots and island arcs/backarcs typically have enriched trace element and isotopic compositions that contain a contribution from subducted oceanic crust. Isotopic and trace element data suggest that the enriched components in hotspot volcanism are ancient subducted sediment and crust, and the enriched components in arc/backarc volcanism are...
