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 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 …

The chemical composition of the bulk silicate Earth (BSE) indicates that the present‐day
thermal budget of Earth is likely to be characterized by a significant excess of surface heat …

ODP/IODP Hole 1256D penetrates an in situ section of ocean crust formed at the East
Pacific Rise, through lavas and sheeted dikes and∼ 100 m into plutonic rocks. We use …

In ophiolites and in present-day oceanic crust formed at fast spreading ridges, oceanic
plagiogranites are commonly observed at, or close to the base of the sheeted dike complex …

The brittle to ductile transition (BDT) in rocks may strongly influence their transport properties
(ie, permeability, porosity topology…) and the maximum depth and temperature where …

Whereas the majority of eruptions at oceanic spreading centers produce lavas with relatively
homogeneous mid-ocean ridge basalt (MORB) compositions, the formation of tholeiitic …

Nitrogen contents and isotope compositions together with major and trace element
concentrations were determined in a sequence of metagabbros from the western Alps …

The formation of oceanic plagiogranite has been attributed primarily to either 1) extreme
fractional crystallization of a mantle melt, or 2) partial melting of hydrated mafic crust, with …

This paper presents the first detailed geologic map of in situ lower ocean crust; the product
of six surveys of Atlantis Bank on the SW Indian Ridge. This combined with major and trace …
