Abyssal peridotites are ultramafic rocks collected from mid-ocean ridges that are the
residues of adiabatic decompression melting. Their compositions provide information on the …

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 …

A systematic study of rare earth and other trace elements in discrete diopsides from residual
abyssal peridotites sampled from 5000 km of ocean ridge demonstrates that they are the …

This paper presents the results of the first quantitative petrological modelling of abyssal
peridotites. The mantle beneath a ridge may be considered as two regions:(1) the melting …

Gravity data from the Mid-Atlantic Ridge between latitudes 27° 50′ N and 30° 40′ N show
that the accretion of magma at the ridge is focused at discrete centres along the spreading …

To decipher the distribution of mass anomalies near the earth's surface and their relation to
the major tectonic elements of a spreading plate boundary, we have analyzed shipboard …

Anisotropic inversions of surface wave data show that the variations in vertical shear
velocity, βv, and anisotropy of the oceanic upper mantle in the Pacific are much smoother …

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 …

Thermal models based on the geometry of axial segmentation, and mechanical models of
axial valley formation, suggest that the axial lithosphere of slow spreading ridges can be …

The contrast in geologic structure observed on opposing flanks of the Mid‐Atlantic Ridge,
where it is offset by the Atlantis transform fault, illustrates how significant differences in …
