LangeAmyCEOASPetrogenesisPlagioclase-Phyric.pdf

Creator:: Lange, Amy E., Nielsen, Roger L., Tepley, Frank J., III, and Kent, Adam J. R.
Abstract:: Plagioclase ultraphyric basalts (PUBs) have been sampled along most mid-ocean ridges with ultraslow to intermediate spreading rates. Over the past 40 years, the prevalent models for their origin assume positive buoyancy of plagioclase in basaltic liquids resulting in selective concentration of plagioclase phenocrysts by floatation. However, when the global population...

PisiasNicklasCEOASMultivariateStatisticalAnalysis.pdf

Creator:: Pisias, Nicklas G., Murray, Richard W., and Scudder, Rachel P.
Abstract:: Multivariate statistical treatments of large data sets in sedimentary geochemical and other fields are rapidly becoming more popular as analytical and computational capabilities expand. Because geochemical data sets present a unique set of conditions (e.g., the closed array), application of generic off-the-shelf applications is not straightforward and can yield misleading...

Creator:: Stoner, Joseph S., Channell, James E. T., Mazaud, Alain, Strano, Sarah E., and Xuan, Chuang
Abstract:: Paleomagnetic analysis and radiocarbon dating of an expanded Holocene deep-sea sediment sequence recovered by Integrated Ocean Drilling Program (IODP) Expedition 303 from Labrador Sea Site U1305 (Lat.: 57°28.5 N, Long.: 48°31.8 W, water depth 3459 m) provides insights into mechanisms that drive both paleomagnetic secular variation (PSV) and magnetization acquisition...

Creator:: Chadwick, William W., Jr., Clague, D. A., Embley, R. W., Perfit, M. R., Butterfield, D. A., Caress, D. W., Paduan, J. B., Martin, J. F., Sasnett, P., Merle, S. G., and Bobbitt, A. M.
Abstract:: Axial Seamount, an active submarine volcano on the Juan de Fuca Ridge at 46°N, 130°W, erupted in January 1998 along 11 km of its upper south rift zone. We use ship-based multibeam sonar, high-resolution (1 m) bathymetry, sidescan sonar imagery, and submersible dive observations to map four separate 1998 lava...

Creator:: Cromwell, G., Tauxe, L., Staudigel, H., Constable, C. G., Koppers, A. A. P., and Pedersen, R. -B.
Abstract:: Investigations of the behavior of the geomagnetic field on geological timescales rely on globally distributed data sets from dated lava flows. We present the first suitable data from the Arctic region, comprising 37 paleomagnetic directions from Jan Mayen (71°N, 0.2–461 ka) and Spitsbergen (79°N, 1–9.2 Ma) and five paleointensity results....

Abstract:: Estimates of the relative motion between the Hawaiian and Louisville hot spots have consequences for understanding the role and character of deep Pacific-mantle return flow. The relative motion between these primary hot spots can be inferred by comparing the age records for their seamount trails. We report ⁴⁰Ar/³⁹Ar ages for...

Creator:: Loewen, Matthew W., Duncan, Robert A., Kent, Adam J. R., and Krawl, Kyle
Abstract:: We present 36 new ⁴⁰Ar-³⁹Ar incremental heating age determinations from the Caribbean Large Igneous Province (CLIP) providing evidence for extended periods of volcanic activity and suggest a new tectonomagmatic model for the province’s timing and construction. These new ⁴⁰Ar-³⁹Ar ages for the Curaçao Lava Formation (CLF) and Haiti’s Dumisseau Formation...

Convergent crater circulations on Mars: Influence on the surface pressure cycle and the depth of the convective boundary layer

Creator:: Tyler, Daniel Jr and Barnes, Jeffrey R.
Abstract:: Modeling of slope flow circulations in idealized axisymmetric craters is used to understand (1) the large surface pressure amplitude observed in Gale Crater by the Rover Environmental Monitoring Station and (2) the shallow convective boundary layer (CBL) suggested by Curiosity imagery. Air temperatures vary within craters with greater amplitudes than...

Abstract:: Multibeam (1 m resolution) and side scan data collected from an autonomous underwater vehicle, and lava samples, radiocarbon-dated sediment cores, and observations of flow contacts collected by remotely operated vehicle were combined to reconstruct the geologic history and flow emplacement processes on Axial Seamount’s summit and upper rift zones. The...

Deeply dredged submarine HIMU glasses from the Tuvalu Islands, Polynesia: Implications for volatile budgets of recycled oceanic crust

Creator:: Jackson, M. G., Koga, K. T., Price, A., Koppers, A. A. P., Finlayson, V. A., Konrad, K., Hauri, E. H., Kylander-Clark, A., Kelley, K. A., and Kendrick, M. A.
Abstract:: Ocean island basalts (OIB) with extremely radiogenic Pb-isotopic signatures are melts of a mantle component called HIMU (high µ, high ²³⁸U/²⁰⁴Pb). Until now, deeply dredged submarine HIMU glasses have not been available, which has inhibited complete geochemical (in particular, volatile element) characterization of the HIMU mantle. We report major, trace...
