Mantle melting and melt extraction processes beneath ocean ridges: evidence from abyssal peridotites

Y Niu - Journal of Petrology, 1997 - academic.oup.com
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 …

Emplacement of mantle rocks in the seafloor at mid‐ocean ridges

M Cannat - Journal of Geophysical Research: Solid Earth, 1993 - Wiley Online Library
This paper discusses the geological and geophysical data available on mid‐ocean ridges
with outcrops of serpentinized mantle peridotites, with the objective of better constraining the …

Solidification fronts and magmatic evolution

BD Marsh - Mineralogical Magazine, 1996 - cambridge.org
From GF Becker's and LV Pirsson's early enunciations linking the dynamics of magma
chambers to the rock records of sills and plutons to this day, two features stand at the centre …

The formation of SiO2-rich melts within the deep oceanic crust by hydrous partial melting of gabbros

J Koepke, J Berndt, ST Feig, F Holtz - Contributions to Mineralogy and …, 2007 - Springer
Small amounts of felsic, evolved plutonic rocks, often called oceanic plagiogranites, always

Seismic anisotropy of oceanic upper mantle: Shear wave splitting methodologies and observations

CJ Wolfe, PG Silver - Journal of Geophysical Research: Solid …, 1998 - Wiley Online Library
We develop methodologies to obtain accurate measurements of shear wave splitting and
apply these techniques to examine the pattern of oceanic upper mantle anisotropy. To …

The thermal state of the upper mantle; no role for mantle plumes

DL Anderson - Geophysical Research Letters, 2000 - Wiley Online Library
A variety of geophysical data indicates that long wavelength temperature variations of the
asthenosphere depart from the mean by±200° C, not the±20° C adopted by plume …

How thick is the magmatic crust at slow spreading oceanic ridges?

M Cannat - Journal of Geophysical Research: Solid Earth, 1996 - Wiley Online Library
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 …
