Major-element data for oceanic basalts are important because they can be quantitatively linked to mantle temperatures, axial depth of oceanic ridges, crustal thickness and seismic tomography 6,7,8,9.

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 ...

The oceanic lithosphere covers two-thirds of our planet: understanding how it forms and evolves is a major challenge in the Earth sciences. It is generally agreed that the oceanic lithosphere forms ...

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 ...

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 ...

Europa’s surface as seen by NASA’s Galileo probe, with a prominent double-ridge system running from the lower left to the upper right. The feature could function similarly to a mid-oceanic ridge on ...

This is a preview. Log in through your library . Abstract The offsets of the axis of the Mid-Atlantic Ridge in equatorial fracture zones are characterized by the existence of transverse ridges running ...

The oceanic crust at North Pond is relatively young (8 million years old) and its circulating fluids are cold (<20 degrees C). By comparison, the temperature of crustal fluids can reach 400 degrees C ...
