Ridge Migration and Plate Boundary Readjustments at the Rodriguez Triple Junction

Geophysical Research Letters
The Rodriguez Triple Junction (RTJ) marks the intersection of the Indian Ocean's three principal mid‐ocean ridges and is a type locality for Ridge‐Ridge‐Ridge triple junctions.

Chemical Variations in the 1998, 2011, and 2015 Lava Flows From Axial Seamount, Juan de Fuca Ridge: Cooling During Ascent, Lateral Transport, and Flow

Geochemistry, Geophysics, Geosystems, 2018
Lava flows erupted at Axial Seamount in 1998, 2011, and 2015 are chemically heterogeneous and display decreases in MgO content in their glass rinds with increasing distance from the summit.

Hydrothermal Discharge During Submarine Eruptions: The Importance of Detection, Response, and New Technology [PDF]

Oceanography, 2012
Submarine volcanic eruptions and intrusions construct new oceanic crust and build long chains of volcanic islands and vast submarine plateaus. Magmatic events are a primary agent for the transfer of heat, chemicals, and even microbes from the crust to ...

The Effects of a Microplate on Plume‐Ridge Interactions: Constraints From Comparing Easter and Juan Fernandez Microplates in the Eastern Pacific Ocean

Geochemistry, Geophysics, Geosystems
This study investigates the nature of plume‐ridge interactions near a tectonic microplate using mantle Bouguer anomaly (MBA) gravity calculations. The focus of this investigation is a comparison of the Easter and Juan Fernandez microplates, which are ...

Persistent Heterogeneities in the Oceanic Lithosphere Due To Differential Freezing Beneath Ridges

Geophysical Research Letters
Oceanic lithosphere, which forms two‐thirds of Earth's surface, is generated at mid‐ocean ridge spreading centers. Yet the internal structure of the lithosphere is not well characterized and often considered to be homogeneous relative to the structure of

Large-scale groundwater flow and sedimentary diagenesis in continental shelves influence marine chemical budgets

Nature Communications
The major ion chemistry of the ocean has been assumed to be controlled by river input, hydrothermal circulation at mid-ocean ridges, carbonate production, and low-temperature alteration of seafloor basalt, but marine chemical budgets remain difficult to ...

The geodynamics of plume-influenced mid-ocean ridges: insights from the Foundation Segment of the Pacific-Antarctic Ridge

Frontiers in Earth Science
The intersection of the Foundation Plume with the Pacific-Antarctic Ridge is a key location in global geodynamics where a mantle plume is approached by and interacting with a fast-spreading mid-ocean ridge.
