We present a new synthesis of oceanic crustal structure from two‐dimensional seismic
profiles to explore differences related to spreading rate and age. Primary results are as …

The title" Geophysical constraints on mantle flow and melt generation beneath mid-ocean
ridges" can be interpreted in two ways: either as observational constraints on models, or as …

Three approaches are used to reduce the error in the satellite‐derived marine gravity
anomalies. First, we have retracked the raw waveforms from the ERS‐1 and Geosat/GM …

New investigations of the Southwest Indian and Arctic ridges reveal an ultraslow-spreading
class of ocean ridge that is characterized by intermittent volcanism and a lack of transform …

The subducting oceanic lithosphere may carry a large amount of chemically bound water
into the deep Earth interior, returning water to the mantle, facilitating melting, and hence …

In this study we construct a thermal and mechanical model for the genesis of oceanic crust.
Magma is halted in its ascent within the oceanic crust when it reaches a freezing horizon …

A high-resolution mapping and sampling study of the Gakkel ridge was accomplished during
an international ice-breaker expedition to the high Arctic and North Pole in summer 2001 …

Away from the influence of fracture zones, hotspots and marginal basins, oceanic crust
exhibits remarkably uniform crustal thickness, rare earth element concentrations and bulk …

First‐order (transform) and second‐order ridge‐axis discontinuities create a fundamental
segmentation of the lithosphere along mid‐ocean ridges, and in slow spreading crust they …

The boundary between Earth's crust and mantle is commonly modelled as a discontinuity
surface, the so-called Moho. Although in some regions of the world this model may be too …
