A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the ...

A new study published in the Proceedings of the National Academy of Sciences provides scientists with a powerful new tool for ...

Scientists have discovered a new "ultra-slow" class of ocean ridge involved in seafloor spreading. Investigations in the remote regions of the planet--in the far south Atlantic and Indian Oceans and ...

Preface / W. Roger Buck...[et al] -- Global systematics of mid-ocean ridge morphology / Christopher Small -- Linkages between faulting, volcanism, hydrothermal activity and segmentation on fast ...

Ken Sims, a professor in UW’s Department of Geology and Geophysics, recently received a $325,841 National Science Foundation grant to look at understanding the processes and timescales of basalt ...

THE theory of ocean floor spreading requires that oceanic crust be generated at mid-ocean ridges. Evidence from a variety of sources suggests that the new crust is made largely of basalt and gabbro, ...

Sometimes in science, even a successful prediction isn’t enough. Earlier this year, we covered some research suggesting that ice age fluctuations in sea level influenced the volcanism at mid-ocean ...

Image: Tiny crystals called zircons are used to date oceanic crust. A newly developed method that detects tiny bits of zircon in rock reliably predicts the age of ocean crust more than 99 percent of ...
