Abstract:: An interlaboratory study of Mg/Ca and Sr/Ca ratios in three commercially available carbonate reference materials (BAM RS3, CMSI 1767, and ECRM 752-1) was performed with the participation of 25 laboratories that determine foraminiferal Mg/Ca ratios worldwide. These reference materials containing Mg/Ca in the range of foraminiferal calcite (0.8 mmol/mol to...

Temporal and crustal effects on differentiation of tholeiite to calcalkaline and ferro-trachytic suites, High Lava Plains, Oregon, USA

Creator:: Streck, Martin J. and Grunder, Anita L.
Abstract:: Strongly bimodal, basalt-rhyolite volcanism of the High Lava Plains Province of Oregon followed the Middle Miocene flood basalts of the Pacific Northwest and extends to recent time. During the 8 m.y. of volcanism recorded in the central High Lava Plains, in western Harney Basin, three distinct mafic magmatic trends originate...

Spatial and temporal distribution of a C-like asthenoshpheric component in the Rano Rahi Seamount Field, East Pacific Rise, 15°-19°S

Creator:: Hall, L. S., Mahoney, J. J., Sinton, J. M., and Duncan, Robert A.
Abstract:: Lavas of the Rano Rahi seamount field define a Nd-Pb-Sr isotopic array that connects, and substantially overlaps, the arrays of the nearby East Pacific Rise axis and 5.6–28 Ma lavas of the Pukapuka ridge system, situated between the seamount field and French Polynesia. Dating of Rano Rahi samples by ⁴⁰Ar-³⁹Ar...

Short-lived and discontinuous intraplate volcanism in the South Pacific: Hot spots or extensional volcanism?

Creator:: Koppers, Anthony A. P., Staudigel, Hubert, Pringle, Malcolm S., and Wijbrans, Jan R.
Abstract:: South Pacific intraplate volcanoes have been active since the Early Cretaceous. Their HIMU-EMI-EMII mantle sources can be traced back into the West Pacific Seamount Province (WPSP) using plate tectonic reconstructions, implying that these distinctive components are enduring features within the Earth's mantle for, at least, the last 120 Myr. These...

Late Pleistocene stratigraphy of IODP Site U1396 and compiled chronology offshore of south and south west Montserrat, Lesser Antilles

S. V., Tamura, Yoshihiko, Villemant, Benoit, and Wang, Fei
Abstract:: Marine sediments around volcanic islands contain an archive of volcaniclastic deposits, which can be used to reconstruct the volcanic history of an area. Such records hold many advantages over often incomplete terrestrial data sets. This includes the potential for precise and continuous dating of intervening sediment packages, which allow a...

Submarine record of volcanic island construction and collapse in the Lesser Antilles arc: First scientific drilling of submarine volcanic island landslides by IODP Expedition 340

V., Tamura, Y., Trofimovs, J., Voight, B., Wall-Palmer, D., Wang, F., and Watt, S. F. L.
Abstract:: IODP Expedition 340 successfully drilled a series of sites offshore Montserrat, Martinique and Dominica in the Lesser Antilles from March to April 2012. These are among the few drill sites gathered around volcanic islands, and the first scientific drilling of large and likely tsunamigenic volcanic island-arc landslide deposits. These cores...

Seamount morphology in the Bowie and Cobb hot spot trails, Gulf of Alaska

Creator:: Chaytor, Jason D., Keller, Randall A., Duncan, Robert A., and Dziak, Robert P.
Abstract:: Full-coverage multibeam bathymetric mapping of twelve seamounts in the Gulf of Alaska reveals that they are characterized by flat-topped summits (rarely with summit craters) and by terraced, or step-bench, flanks. These summit plateaus contain relict volcanic features (e.g., flow levees, late-stage cones, and collapse craters) and as such must have...

New ⁴⁰Ar/³⁹Ar age progression for the Louisville hot spot trail and implications for inter–hot spot motion

Creator:: Koppers, Anthony A. P., Gowen, Molly D., Colwell, Lauren E., Gee, Jeffrey S., Lonsdale, Peter F., Mahoney, John J., and Duncan, Robert A.
Abstract:: In this study we present 42 new ⁴⁰Ar/³⁹Ar incremental heating age determinations updated age progression for the Louisville seamount trail. Louisville is the South Hawaiian‐Emperor seamount trail, both trails representing intraplate volcanism (~80 Ma to present) and being examples of primary hot spot lineaments. Our age‐progressive trend from 71 to...

Correlated geophysical, geochemical, and volcanological manifestations of plume-ridge interaction along the Galápagos Spreading Center

Creator:: Detrick, R. S., Sinton, J. M., Ito, G., Canales, J. P., Behn, M., Blacic, T., Cushman, B., Dixon, J. E., Graham, David W., and Mahoney, J. J.
Abstract:: As the Galápagos hot spot is approached from the west along the Galápagos Spreading Center there are systematic increases in crustal thickness and in the K/Ti, Nb/Zr, ³He/⁴He, H₂O, and Na₂O content of lavas recovered from the spreading axis. These increases correlate with progressive transitions from rift valley to axial...

Age systematics of two young en echelon Samoan volcanic trails

Creator:: Koppers, Anthony A. P., Russell, Jamie A., Roberts, Jed, Jackson, Matthew G., Konter, Jasper G., Wright, Dawn J., Staudigel, Hubert, and Hart, Stanley R.
Abstract:: The volcanic origin of the Samoan archipelago can be explained by one of three models, specifically, by a hot spot forming over a mantle plume, by lithospheric extension resulting from complex subduction tectonics in the region, or by a combination of these two processes, either acting sequentially or synchronously. In...
