Sulfur K-edge XANES analysis of natural and synthetic basaltic glasses: Implications for S speciation and S content as function of oxygen fugacity
TL;DR: XANES analyses at the sulfur K-edge were used to determine the oxidation state of S species in natural and synthetic basaltic glasses and to constrain the fO2 conditions for the transition from sulfide (S 2� ) to sulfate (S 6+ ) in silicate melts as mentioned in this paper.

The fate of sulfide during decompression melting of peridotite - implications for sulfur inventory of the MORB-source depleted upper mantle
Shuo Ding,Rajdeep Dasgupta +1 more
TL;DR: In this article, the authors developed a model to describe the behavior of sulfide and Cu during decompression melting by combining the pMELTS thermodynamic model and empirical sulfur contents at sulfide concentration (SCSS) models, taking into account the effect of the presence of Ni and Cu in sulfides on SCSS of mantle-derived melts.

TL;DR: The 2014-2015 Holuhraun fissure eruption provided a rare opportunity to study in detail the magmatic processes and magma plumbing system dynamics during a 6-month-long, moderate-to large-volume basaltic fissures eruption.

Sulphur isotopes of alkaline magmas unlock long-term records of crustal recycling on Earth.
William Hutchison,Ranier Babiel,Adrian A. Finch,Michael A.W. Marks,Gregor Markl,Adrian J. Boyce,Eva E. Stüeken,Henrik Friis,A. Borst,Nicola J. Horsburgh +9 more
TL;DR: A billion-year-old alkaline province in Greenland is investigated and an enriched subduction-influenced source (δ34S of +1 to +5‰) can be reconstructed, thus alkaline rocks can be used to reveal crustal recycling through geological time.

The composition of the Earth
William F. McDonough,Shen-Su Sun +1 more
TL;DR: In this paper, the authors compared the relative abundances of the refractory elements in carbonaceous, ordinary, and enstatite chondritic meteorites and found that the most consistent composition of the Earth's core is derived from the seismic profile and its interpretation, compared with primitive meteorites, and chemical and petrological models of peridotite-basalt melting relationships.

Current plate motions
TL;DR: A global plate motion model, named NUVEL-1, which describes current plate motions between 12 rigid plates is described, with special attention given to the method, data, and assumptions used as discussed by the authors.
Current plate motions
TL;DR: In this paper, a new global model (NUVEL-1) was proposed to describe the geologically current motion between 12 assumed-rigid plates by inverting plate motion data.

TL;DR: In this article, a regular solution-type thermodynamic model for twelve-component silicate liquids in the system SiO2-TiO 2-Al 2O3-Fe2O 3-Cr2O3 -FeO-MgO-CaO-Na2O-K 2O-P2O5-H2O is calibrated.

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.
