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 …

Mid-ocean ridge basalts (MORB) provide fundamental information about the composition
and melting processes in the Earth's upper mantle. To use MORB to further our …

Convective circulation of the mantle causes deflections of the Earth's surface that vary as a
function of space and time. Accurate measurements of this dynamic topography are …

The oceanic crust is formed by a combination of magmatic and tectonic processes at mid‐
ocean spreading centers. Under ultraslow spreading environment, however, observations of …

The thermal state of mid-ocean ridges exerts a crucial modulation on seafloor spreading
processes that shape~ 2/3 of our planet's surface. Standard thermal models treat the ridge …

Since the late 1970s studies of the oceanic crust using airgun sources and towed
hydrophone arrays have been conducted in a wide range of ocean basin settings including …

Melt supply at the ultraslow‐spreading Southwest Indian Ridge (SWIR) has been shown to
vary from nearly amagmatic, leading to ultramafic seafloor, to magmatically robust …

Ultraslow-spreading ridges are a novel class of spreading centers symbolized by amagmatic
crustal accretion, exposing vast amounts of mantle-derived peridotites on the seafloor …

The crustal accretion along mid-ocean ridges is known to be spreading-rate dependent.
Along fast-spreading ridges, two-dimensional sheet-like mantle upwelling creates relatively …

Reaction between mid‐ocean ridge basalt (MORB) and crystal mush in the lower oceanic
crust has been invoked to explain chemical variations of both MORB and minerals in the …
