TLDR
In this article, the authors study the dynamics of melting in the Hawaiian plume using a 3D variable-viscosity convection model outfitted with a melting parameterization that permits calculation of the local melting rate and the distribution of buoyant depleted residual material.About:

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.
Journal ArticleDOI
Iron corrosion by novel anaerobic microorganisms
TL;DR: Novel marine, corrosive types of SRB obtained via an isolation approach with metallic iron as the only electron donor are described, suggesting that the novel surface-attached cell type obtained electrons from metallic iron in a more direct manner than via free hydrogen.

Petrology of some oceanic island basalts: PRIMELT2.XLS software for primary magma calculation
Claude Herzberg,Paul D. Asimow +1 more
TL;DR: The PRIMELT2.XLS software as discussed by the authors is an upgrade over a previous version in that it includes garnet peridotite melting and it detects complexities that can lead to overestimates in mantle potential temperature by >100°C.

Mantle Convection and Plate Tectonics: Toward an Integrated Physical and Chemical Theory
TL;DR: There has been rapid progress on these two problems, with the emergence of the first self-consistent models of plate tectonics and mantle convection, along with new geochemical models that may be consistent with seismic and dynamical constraints on mantle structure.

Identification of Source Lithology in the Hawaiian and Canary Islands: Implications for Origins
TL;DR: In this article, an exploration of mantle source lithology for intraplate magmas using whole-rock and olivine phenocryst compositions was conducted using low and high-temperature reference frames.

New version of the generic mapping tools

TL;DR: GMT is a public domain collection of UNIX tools that contains programs to manipulate (x,y,z) data and to generate PostScript illustrations, including simple x-y diagrams, contour maps, color images, and artificially illuminated, perspective, shaded-relief plots using a variety of map projections.

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.
