Water in the oceanic upper mantle: implications for rheology, melt extraction and the evolution of the lithosphere
Greg Hirth,David L. Kohlstedt +1 more
TLDR
In this paper, the influence of water on the dynamics of the oceanic upper mantle is re-evaluated based on recent experimental constraints on the solubility of water in mantle minerals and earlier experimental studies of olivine rheology.About:

Major and trace element composition of the depleted MORB mantle (DMM)
R. Workman,Stanley R. Hart +1 more
TL;DR: Asimow et al. as mentioned in this paper derived an estimate for the chemical composition of the depleted MORB mantle (DMM), the source reservoir to mid-ocean ridge basalts (MORBs), which represents at least 30% the mass of the whole silicate Earth.

Rheology of the Upper Mantle and the Mantle Wedge: A View from the Experimentalists
Greg Hirth,David L. Kohlstedt +1 more
TL;DR: In this paper, the authors provide a critical review of flow law parameters for olivine aggregates and single crystals deformed in the diffusion creep and dislocation creep regimes under both wet and dry conditions.
Journal ArticleDOI
The mean composition of ocean ridge basalts
TL;DR: In this article, the mean composition of mid-ocean ridge basalts (MORB) is determined using a global data set of major elements, trace elements, and isotopes compiled from new and previously published data.
Journal ArticleDOI
The global range of subduction zone thermal models
TL;DR: In this article, a suite of thermal models for the global subduction system is presented, where the authors model 56 segments of subduction zones using kinematically defined slabs based on updated geometries from Syracuse and Abers (2006).

An olivine-free mantle source of Hawaiian shield basalts
Alexander V. Sobolev,Albrecht W. Hofmann,Stephan V. Sobolev,Igor K. Nikogosian,Igor K. Nikogosian +4 more
TL;DR: Modelling shows that more than half of Hawaiian magmas formed during the past 1 Myr came from a deep olivine-bearing source, and the proportion of recycled (oceanic) crust varies from 30 per cent near the plume centre to insignificant levels at the plumes edge.

An analysis of the variation of ocean floor bathymetry and heat flow with age
Barry Parsons,John G. Sclater +1 more
TL;DR: In this paper, a simple cooling model and the plate model were proposed to account for the variation in depth and heat flow with increasing age of the ocean floor. But the results were limited to the North Pacific and North Atlantic basins.

Trace element fractionation during anatexis
TL;DR: The theoretical basis of trace element fractionation presented in a paper by P. W. Gast (1968) can be developed in a more flexible algebraic form, which is described and illustrated in this article.

Rheology of the Upper Mantle: A Synthesis
Shun-ichiro Karato,Patrick Wu +1 more
TL;DR: A synthesis of laboratory studies and geophysical and geological observations shows that transitions between diffusion and dislocation creep likely occur in the Earth's upper mantle.

Global correlations of ocean ridge basalt chemistry with axial depth and crustal thickness
TL;DR: In this paper, the global major element variations can be explained by ∼8-20% melting of the mantle at associated mean pressures of 5-16 kbar, and the lowest extents of melting occur at shallowest depths in the mantle and are associated with the deepest ocean ridges.
