TL;DR: In this article, the authors discuss the geological and geophysical data available on mid-ocean ridges with outcrops of serpentinized mantle peridotites, with the objective of better constraining the modes of emplacement of these rocks in the seafloor.

TL;DR: In this paper, the authors find a good correlation between domains of positive residual gravity anomalies (inferred to have a thin crust) and the distribution of ultramafic samples and also find that thin-crust domains have a rugged topography, thought to reflect strong tectonic disruption.

TL;DR: In this paper, the authors report on extensive off-axis bathymetry, gravity, and magnetic data that provide a 26m.y.d. record of axial tectonic and magmatic processes over a 660km-long and melt-poor portion of the ultralow Southwest Indian Ridge.

TL;DR: In this article, a geological model is proposed for the lithosphere created in these thick lithosphere/thin crust ridge regions, which suggests that crustal thicknesses measured in seismic surveys of these regions do not directly reflect the melt production in the asthenosphere beneath the ridge, and part of the crust is made of variably fractured and serpentinized residual ultramafics.

TL;DR: In this paper, it was shown that the magmatic crust is very thin and locally discontinuous in large areas of the central Atlantic Ocean and that these peculiar aspects of the present-day structure of a slow-spreading major ocean are found in the ophiolites of the western Alps as well as in the Ligurian ophilia of the Apennines.
