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

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 ...

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 ...

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 ...
