Diversity of Hydrothermal Systems on Slow Spreading Ocean Ridges
Slow Spreading Ocean Ridges Hydrothermal Systems
2015/7/16
The global mid-ocean ridge system spreads over a spectrum of rates, and oceanic crust formed at slow and ultra-slow spreading ridges (< 40 mm yr–1) differs from the more "ideal" layered structure form...

Long-Lived Faults Emerging Slow-Spreading Mid-Ocean Ridges
2015/7/14
In the classic mid-ocean ridge model, new seafloor is generated through a combination of magmatic diking feeding lava flows at the spreading axis, and the formation of short-offset, high-angle normal ...
The Prediction,Verification,and Significance of Flank Jets at Mid-Ocean Ridges
Prediction Verification Significance Flank Jets Mid-Ocean Ridges
2015/7/14
One aspect of ocean flow over mid-ocean ridges that has escaped much attention is the capacity of a ridge to convert oscillatory flows into unidirectional flows. Those unidirectional flows take the fo...
Diffuse Flow On and Around Hydrothermal Vents at Mid-Ocean Ridges
Around Hydrothermal Vents Mid-Ocean Ridges
2015/7/14
Black smokers are the dramatic result of seawater being heated to high temperatures (generally 250° to 350°C) by magmatic systems, then discharging at the seafloor. However, not all seawater that circ...
Future accreted terranes: a compilation of island arcs, oceanic plateaus, submarine ridges, seamounts, and continental fragments

2015/1/6
Allochthonous accreted terranes are exotic geologic units that originated from anomalous crustal regions on a subducting oceanic plate and were transferred to the overriding plate by accretionary proc...

Seismic structure the lithosphere and upper mantle beneath ocean islands near mid-oceanic ridges
2015/1/6
Deciphering the seismic character of the young lithosphere near mid-oceanic ridges (MORs) is a challenging endeavor. In this study, we determine the seismic structure of the oceanic plate near the MOR...
