Sulfide geochronology along the Endeavour Segment of the Juan de Fuca Ridge [PDF]

, 2013
Forty-nine hydrothermal sulfide-sulfate rock samples from the Endeavour Segment of the Juan de Fuca Ridge, northeastern Pacific Ocean, were dated by measuring the decay of 226Ra (half-life of 1600 years) in hydrothermal barite to provide a history of ...

Hydrothermal circulation within the Endeavour Segment, Juan de Fuca Ridge [PDF]

Geochemistry, Geophysics, Geosystems, 2010
Areas of the seafloor at mid‐ocean ridges where hydrothermal vents discharge are easily recognized by the dramatic biological, physical, and chemical processes that characterize such sites. Locations where seawater flows into the seafloor to recharge hydrothermal cells within the crustal reservoir are by contrast almost invisible but can be indirectly ...

Endeavour Segment of the Juan de Fuca Ridge: One of the Most Remarkable Places on Earth [PDF]

Oceanography, 2012
Endeavour Segment of the Juan de Fuca Ridge is one of three Integrated Study Sites for the Ridge 2000 Program. It is a remarkable, dynamic environment hosting five major hydrothermal fields, numerous smaller fields, and myriad diffuse-flow sites; magma ...

Near‐axis crustal structure and thickness of the Endeavour Segment, Juan de Fuca Ridge

Geophysical Research Letters, 2016
A model of crustal thickness and lower crustal velocities is obtained for crustal ages of 0.1–1.2 Ma on the Endeavour Segment of the Juan de Fuca Ridge by inverting travel times of crustal paths and non‐ridge‐crossing wide‐angle Moho reflections obtained

Changing Brine Inputs Into Hydrothermal Fluids: Southern Cleft Segment, Juan de Fuca Ridge

Geochemistry, Geophysics, Geosystems, 2020
In 2016, temperature recorders were recovered, temperatures were measured, and fluid samples were collected from Vent 1, a high temperature (338°C) hydrothermal discharge site on the southern Cleft Segment of the Juan de Fuca Ridge. Coupled with previous

Hydrothermal circulation at the Cleft-Vance overlapping spreading center : results of a magnetometric resistivity survey [PDF]

, 1998
We report on a magnetometric resistivity sounding carried out in the overlapping spreading center between the Cleft and Vance segments of the Juan de Fuca Ridge.

Seafloor Positioning Across Juan De Fuca Ridge

, 1994
Abstract : The results of an analysis of a complex data set acquired during the United States Geological Survey's Marine Crustal Deformation Study are presented. The experiment, which commenced in the spring of 1992 in a region of the Pacific known as the Juan de Fuca ridge, represents a first attempt to locally monitor plate dynamics in the marine ...

A 65 k.y. time series from sediment-hosted glasses reveals rapid transitions in ocean ridge magmas [PDF]

, 2017
Studies of ocean ridge magmatism have been hampered by the difficulty in constructing time-series data over more than a few thousand years. Sediment rapidly covers newly formed ocean crust, and older rocks, even when recovered from fault scarps, cannot ...
