Journal ArticleDOI
Role of the deep mantle in generating the compositional asymmetry of the Hawaiian mantle plume
TL;DR: In this paper, the authors show that the anomalous low-velocity zones at the core-mantle boundary are storing geochemical anomalies that are enriched in recycled material and sampled by strong mantle plumes and conclude that the geochemical differences between the Kea and Loa trends reflect preferential sampling of these two distinct sources of deep mantle material.
Book ChapterDOI
Olivine‐Rich Submarine Basalts from the Southwest Rift Zone of Mauna Loa Volcano: Implications for Magmatic Processes and Geochemical Evolution
TL;DR: In this article, the authors made a multibeam survey of the southwest rift zone of Mauna Loa and found that olivine-rich basalts are extremely abundant along the submarine portion of the south side of the volcano and their abundance decreases significantly in the upper parts of the two sections examined.
Journal ArticleDOI
Degassing-induced crystallization of basaltic magma and effects on lava rheology
TL;DR: In this article, the microphenocryst contents of erupted lava increased from 0.5 to 30% without concurrent change in either bulk magma composition or eruption temperature (1,140 ± 3 °C).
Journal ArticleDOI
Spatial and temporal evolution of magmatic systems beneath the endeavour segment, Juan de Fuca Ridge: Tectonic and petrologic constraints
TL;DR: In this article, major and trace element data for a suite of lavas from fifty-six dredges and ALVEN dives on the ridge axis and adjacent abyssal hills have been used to investigate the geometry and evolution of magmatic systems beneath the Endeavour Segment, Juan de Fuca Ridge.
Book ChapterDOI
Isotopic Evolution of Mauna Loa Volcano: A View From the Submarine Southwest Rift Zone
TL;DR: In this article, isotopic and trace element measurements on lavas from the submarine southwest rift zone (SWR) of Mauna Loa continue the temporal trends of subaerial Maun Loa flows, extending the known compositional range for this volcano, and suggesting that many of the SWR lavas are older than any exposed on land.
