Metagabbros with a transitional greenschist-amphibolite-facies mineralogy are exposed on the lower slopes of the eastern wall of the axial valley of the Mid-Atlantic Ridge at 06°N. These metagabbros ...

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

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 ...

A former NASA employee has released a fascinating animation which shows how the look of the planet would change if all the oceans—which cover three fifths of the surface—gradually drained away.

Ocean scientists have discovered a number of mysterious holes in the seafloor that look human-made despite being located 2,540 meters (8,333 feet), or 1.6 mile underwater. The holes were discovered ...

Along submarine mountain ranges, the mid-ocean ridges, forces from the Earth's interior push tectonic plates apart, forming new ocean floor and thus moving continents about. However, many features of ...

Oceanography, Vol. 20, No. 1, SPECIAL ISSUE ON InterRidge (MARCH 2007), pp. 78-89 (12 pages) Allegre, C., and D.L. Turcotte. 1986. Implications of a two component ...

An upsurge of hot rock from deep beneath the Atlantic Ocean may be driving the continents on either side apart. The Americas are moving away from Europe and Africa by a few centimeters each year, as ...

Generally speaking, "ridge subduction" involves subduction of spreading oceanic ridges, aseismic ridges or oceanic plateaus and inactive arc ridges, and this common and important geological process ...

Mid-ocean ridge basalts (MORBs), located far from subduction zones, are typically thought to be unaffected by subduction processes. However, some MORBs display arc-like geochemical ...

Scientists from the Woods Hole Oceanographic Institution (WHOI) have identified a new type of ocean ridge that is spreading so slowly that Earth's mantle is exposed over large regions of the sea floor ...
