Petrogenesis of Plagioclase Ultraphyric Basalts (PUB) From the Northeastern (NE) Pacific Ridge System: Evidence From Mineral Textures and Geochemical Characteristics

Geochemistry, Geophysics, Geosystems
Plagioclase crystals in plagioclase ultraphyric basalts (PUB) record changes in the major, trace, and isotopic compositions of evolving magmas. Those changes represent the record of specific processes in the crust and upper mantle that impart distinct ...

Measurements and Models of Heat Flux and Plumes from Hydrothermal Discharges Near the Deep Seafloor [PDF]

Oceanography, 2012
Deep-sea hydrothermal vents are conduits of heat and chemicals from the lithosphere to the hydrosphere. Their plumes rise hundreds of meters from the seafloor into the water column; during their ascent, they entrain ambient water and are subject to cross

Spotlight 1: Axial Seamount [PDF]

Oceanography, 2010
Axial Seamount is a hotspot volcano superimposed on the Juan de Fuca Ridge (JdFR) in the Northeast Pacific Ocean. Due to its robust magma supply, it rises ~ 800 m above the rest of JdFR and has a large elongate summit caldera with two rift zones that ...

Recent Seismic Studies at the East Pacific Rise 8°20'–10°10'N and Endeavour Segment: Insights into Mid-Ocean Ridge Hydrothermal and Magmatic Processes [PDF]

Oceanography, 2012
As part of the suite of multidisciplinary investigations undertaken by the Ridge 2000 Program, new multichannel seismic studies of crustal structure were conducted at the East Pacific Rise (EPR) 8°20'–10°10'N and Endeavour Segment of the Juan de Fuca ...

Voluminous Inflated Lobate Flows on the Distal Rift Zones of Axial Seamount, Juan de Fuca Spreading Ridge

Geochemistry, Geophysics, Geosystems
Three voluminous inflated lobate lava flow complexes on the distal rifts of Axial Seamount are much larger than other known flows in the global spreading system.
