Mantle anisotropy beneath the Earth's mid-ocean ridges [PDF]
Earth and Planetary Science Letters, 2012 Observations of seismic anisotropy at oceanic spreading centres offer insights into mid-ocean ridge processes and the formation of new plates. Here, remote observations of seismic anisotropy beneath mid-ocean ridges are made using measurements of source ...

The Structure Of Mid-Ocean Ridges
Annual Review of Earth and Planetary Sciences, 1992Recent research results on the structure of midocean ridges are reviewed. The new view of ridge-axis crustal structure obtained from high-resolution seismology is reviewed, emphasizing the variation of that structure with spreading rate and along-axis at a given spreading rate.

Crustal Processes of the Mid-Ocean Ridge
Science, 1981Independent geological and geophysical investigations of the Mid-Ocean Ridge system have begun to focus on the nature of the magma chamber system underlying its central axis. Thermal models predict the existence of a steady-state chamber beneath a thin crustal lid ranging in thickness from 2 to 13 kilometers.

Segmentation of mid-ocean ridges
Nature, 1985Studies of mid-ocean ridges in the Pacific and Atlantic oceans show that the volcanism that forms the oceanic crust along the spreading-plate boundaries is concentrated at regular intervals related to spreading rate. This observation and a new calculation for a Rayleigh–Taylor type of gravitational instability of a partially molten mantle region ...

Offshore Technology Conference, 1980
ABSTRACT Exploration of the Mid-Ocean Ridge in recent years has resulted in a better understanding of its complex geologic processes. This new insight was obtained through the use of a comprehensive mapping approach involving three major mapping systems: multi-narrow beam sonar, ANGUS photography, and manned ...

Iceland and mid-oceanic ridges
Marine Geophysical Researches, 1971Magnetic anomalies over Iceland, measured by Serson et al. (1968), are similar in shape and amplitude to those found over mid-oceanic ridges in general and over Reykjanes Ridge in particular. However, the geology of Iceland does not favour the simple model of sea floor spreading as formulated by Vine and Matthews.

Tectonophysics, 1974
Abstract Various simple models for the emplacement of new material at the mid-oceanic ridge are discussed. Ridges with median valleys and ones without such valleys are considered. The emplacement of both extrusive and intrusive material is taken into account.

On the dynamics of mid‐ocean ridges
Journal of Geophysical Research: Solid Earth, 1988Most extant flow models for ocean ridges suffer either from unrealistic geometry (vertical conduit models) or a stress singularity at the ridge axis (corner flow models). I present a model which avoids these difficulties by incorporating a weak “plate boundary zone” (PBZ) between diverging surface plates.
